Abstract: Objectives. To assess the level of dental radiographers’ compliance with infection control measures and to evaluate the factors affecting their compliance. Methods. The study included 175 dental radiographers. Compliance with infection control was evaluated with a self-administered questionnaire consisting of 33 questions related to vaccination, hand hygiene (HH), personal protective equipment (PPE), disinfection and sterilization, and use of surface barriers. Pearson’s chi-square test was used to compare compliance between subgroups of radiographers. Results. 64.6% of participants were females, and 62.9% was younger than 30 years. 13.0% of the s le population had years of experience and 28.0% take radiographs for patients/day. 66.9% of participants wash their hands before/after taking radiographs. 26.3% of participants had vaccination against hepatitis B, tetanus, and tuberculosis. 12.6% fully use PPE, 10.9% perform complete disinfection and sterilization, and 16.0% apply all kinds of surfaces barriers. Vaccination was significantly affected by age, gender, and practice type. HH was affected by years of experience and number of patients radiographed per day. PPE was influenced by number of hours worked per week and patients radiographed daily. Disinfection and sterilization was affected by practice type and years of experience. The use of surface barriers was affected by age, practice type, and number of patients radiographed/day. Conclusions. The current study indicated poor compliance with infection control practices among dental radiographers. We recommend continuing educational programs and training courses to increase dental radiographers’ awareness of local and international infection control guidelines and to enhance their implementation of these guidelines.

Abstract: AIM: The purpose of the study was to evaluate the knowledge of referring physicians of general practitioners, residents, and medical specialists in Jordan and the Middle East on radiation dose and its impact on vulnerable patients. MATERIALS AND METHODS: The Institutional Review Board approved this study before data collection. A cross-sectional study employed questionnaire that was distributed to respondents (n = 293) of general practitioners, residents, specialists, and therapists. The questionnaire consisted of 29 questions. Nine questions concerned with demographics and the remaining 20 questions were ided into five sections: Radiation dose, ionizing radiation, pediatric radiation, pregnant women radiation, and radiation risks. The mean score was computed out of 20. Chi-squared test of independence was utilized to analyze each question. To compare the responses between the demographic variables groups, Kruskal–Wallis and Mann–Whitney tests were used. RESULTS: Out of the 293 respondents, 128 (43.7%) were aware of radiation. The average score of the questionnaire was 9.5 out of 20 (47.5%). Within each section, the level of knowledge varied. Physicians had the highest level of knowledge in radiation risk (85.7%) followed by ionizing radiation (62.1%). The questionnaire revealed lower levels of knowledge in the areas of pediatric radiation, pregnant women radiation, and radiation dose. The percentages of respondents, (with fair to good level of knowledge), were 47.1%, 34.5%, and 24.6%, respectively. CONCLUSION: The results of this study were consistent with previous studies that demonstrated a poor level of general knowledge in referring physicians regarding radiation dose, ionizing radiation, pediatric radiation, pregnant women radiation, and radiation risks.

Abstract: To determine the impact of mammographic breast density on the visual search process of radiologists when reading digital mammograms. Institutional review board approval was obtained. A set of 149 craniocaudal digital mammograms were read by seven radiologists, and observer search patterns were recorded. Total time examining each case, time to first hit the lesion, dwell time, and number of hits per area were calculated. The nonparametric Mann-Whitney U test was used for statistical evaluation. In both low- and high-mammographic density cases, significant increases were observed in the time to first hit lesions when they were located outside, compared to overlying fibroglandular dense tissue (P = .001). Significantly longer dwell time (P = .003) and greater number of fixations (P = .0003) were observed when the lesions were situated within--rather than outside--the dense fibroglandular tissue. Increased mammographic breast density changes radiologists' visual search patterns. Dense areas of the parenchyma attracted greater visual attention in both high- and low-mammographic density cases, resulting in faster detection of lesions overlying the fibroglandular dense tissue, along with longer dwell times and greater number of fixations, as compared to lesions located outside the dense fibroglandular regions.

Abstract: Previous research on job satisfaction (JS) and burnout has focused on physicians and nurses. However, limited work has evaluated radiographers' JS and burnout, factors affecting them and the correlation between them. The aim of this study is to assess the level and specific factors affecting burnout and JS among radiographers and to examine the correlation between them. A questionnaire consisting of socio-demographic information and two validated instruments (Maslach Burnout Inventory-Human Services Survey for Medical Personnel (MBI-HSS (MP)) and JS Survey (JSS)) was distributed to radiographers. The MBI included 22 questions and JSS consisted of 36 questions. Mean scores were used to compare responses between participants according to demographic characteristics. Correlation between JS and burnout was examined using Pearson correlation test, with P 25 patients per day. Total emotional exhaustion, depersonalization and personal accomplishment scores were 28.7, 11.3 and 35.8 respectively. Most participants felt dissatisfied with pay (n = 221, 71.8%), opportunities for promotion (n = 202, 65.6%), fringe benefits (n = 239, 77.6%), contingent rewards (n = 231, 75.0%), operating procedures (n = 190, 61.7%) and communication (n = 162, 52.6%). Burnout was associated with work experience and caseload and JS was associated with section of work. Most of the JS domains were significantly inversely related to emotional exhaustion and depersonalisation domains. Emotional exhaustion and depersonalization drew a significant positive correlation. Emotional exhaustion and depersonalization drew a significant positive correlation. Participating radiographers are mostly dissatisfied about their jobs and they suffer a high level of emotional exhaustion. To avoid the consequences of burnout and decreased JS on in iduals and organizations, efforts should be done in alleviating the main factors affecting them.

Abstract: Nosocomial infections add health-related and financial burdens on health systems. This study aims to evaluate the radiographers' knowledge of nosocomial infection control practices in Jordan. A cross-sectional questionnaire-based assessment was conducted. The main domains of the knowledge based test were the nature of nosocomial infections, standard precautions, and infection control practices specific to the radiology department. Comparison of knowledge among radiographers was assessed using the Student t-test and ANOVA. Multiple linear regression was used to find predictors of the knowledge score. The final analysis included 100 radiographers from educational, private, and public hospitals. Mean knowledge score was 66.2% (SD: 20.3%, range: 25.0-100%). Questions with the lowest correctly scored were about the main source of infections (17%), recapping used needles (27%), gloves use (27%), the necessity of using overshoes (26%) and a cap (26%) when there is a risk of biological fluid splashes, the necessity of using sterile gloves (7%) and protective masks (5%) during all invasive procedures, the manoeuvrability around a sterile field (54%), and the safety of passing the imaging plate to the scrub nurse in order to place it under the radiographer's direction (37%). Predictors of knowledge score were the academic degree and training status (R Knowledge of infection control practices among Jordanian radiographers was moderate. Future training should focus on handling used needles, the use of protective barriers, and the manoeuvrability around sterile fields. Improved academic curriculum and on-site training could enhance knowledge in infection control practices.

Abstract: Patient positioning is an essential consideration for the optimisation of radiation dose during CT examinations. The study objectives seek to explore the effects of vertical off-centring, localiser direction (0° and 180°), and phantom positioning (supine and prone) on radiation dose, using three different tube voltages in multidetector computed tomography (MDCT) imaging. The trunk of a PBU-60 anthropomorphic phantom was imaged using a Discovery CT750 HD - 128 slice (GE Healthcare). Images employing 0° and 180° localisers were acquired in supine and prone orientation for each combination of vertical off-centring (±100, ±60 and ±30 mm) and different tube voltages (80, 120 and 140 kVp), using the system's automatic tube current modulation (ATCM) function. The displayed volume CT dose index (CTDI With incremental table off-centring of ±100 mm, the dose at 120 kVp in the supine position ranged from 63% to 196% (0° localiser) and from 66% to 191% (180° localiser) as compared to iso-centre. While in the prone position, the dose ranged from 62% to 195% (0° localiser) and 62% to 193% (180° localiser), with a notable dose increase at higher tube voltages. Dose variation and vertical off-centring showed a significant relationship for both 0° and 180° localisers (r = 0.94 and 0.96, respectively, P < 0.001). The CTDI Phantom off-centring and localiser direction evidenced large dose variation. It is recommended that the 0° localiser is employed during CT examinations, in order to minimise the potential additional radiation dose which may result from off-centring and the use of lower tube voltages where clinically appropriate.

Abstract: This study aimed to evaluate the level of knowledge and attitude towards quality control in dental radiography amongst students of dentistry, allied dental sciences and radiologic technology programmes. A cross‐sectional survey was conducted using self‐administered questionnaire on a convenience s le of 580 students from three universities in Jordan. The questionnaire was ided into sections that include personal sociodemographic variables, knowledge about quality assurance in dental radiography and attitude towards quality assurance in dental radiography. A total of 286 students completed the questionnaire (response rate = 49.3%), of whom 70% were women. The respondents’ knowledge scores ranged from 12.2% ( n = 35) to 35.2% ( n = 100). The mean of the quality assurance knowledge scores for the whole study s le was 20.3% ± 14.5%, with no significant difference between men and women ( p = .643). Allied dental sciences students showed significantly higher knowledge scores (25.0 ± 13.0) than dentistry (17.8 ± 14.40) or radiologic technology students (20.9 ± 14.8). The average attitude scores towards quality assurance in dental radiography were fairly good (69.5 ± 26.4) with no statistically significant differences by study programme. Knowledge of students about quality assurance in the three programmes is inadequate. The participants' attitude towards quality assurance was fairly good. The study provides feedback to dental schools to improve their curriculum by including quality assurance into student clinical practices. Further studies are requested to investigate the reasons behind this low level of knowledge.

Abstract: To document the mammographic breast density (MBD) distribution of Jordanian women and the relationship with MBD with age. Correlation between breast cancer diagnosis and density was also explored. A retrospective review of 660 screening mammograms from King Abdullah University Hospital was conducted. Mammograms were classified into 2 groups: normal (return to routine screening) and breast cancer and rated using the American College of Radiology (ACR) Breast Imaging-Reporting and Data System (BI-RADS) 5th edition for MBD. The association between MBD and age was assessed by descriptive analyses and Kruskal-Wallis test. To compare between normal and breast cancer groups, chi-square post hoc tests with Bonferroni adjustment was used. Groups consisted of 73.9% (n = 488) normal group and 26.1% (n = 172) breast cancer group. A significant inverse relationship was demonstrated between age and MBD among the normal ( r = −.319, P .01) and breast cancer group ( r = −.569, P .01). In total, 69% (n = 336) of women in the normal group and 71% (n = 122) in the breast cancer group and 79.1% (n = 159) of the normal group and 100% (n = 48) of the breast cancer group aged 40 to 49 years reported high MBD (ACR BI-RADS c or d). Most of women in both the normal and breast cancer groups evidenced increased MBD. Increased MBD was inversely proportional to age. As MBD has a known link to increased breast cancer risk and the decreased sensitivity of mammography and it is vital that future screening guidelines for Jordanian women consider the unique breast density distribution of this population.

Abstract: A high demand has been placed on radiologists to perform screen reads due to higher number of women undergoing mammography. This study aims to examine radiographer performance in reporting low compared with high-mammographic density (MD) images and to assess the influence of key demographics of Jordanian radiographers on their performance. Thirty mammograms with varied MD were reported by 12 radiographers using the Breast Imaging-Reporting and Data System (BI-RADS). Radiographer performance was measured using sensitivity, specificity, positive (PPV) and negative predictive values (NPV), and area under the receiver operating characteristic curve (ROC AUC). Performance measures were compared between cases with low- and high-MD and between subgroups of radiographers according to key demographics. All performance measures were significantly higher in low- compared to high-MD cases (P value < 0.0). The mean sensitivity, specificity, PPV, NPV and ROC AUC were 0.58, 0.68, 0.67, 0.63 and 0.69 respectively. PPV was significantly different for readers who had different years of experience in mammography, hours and cases per week P value = 0.023, 0.01, 0.017 respectively. ROC AUC was significantly different for radiographers with different number of hours and cases performed per week (P value = 0.001 and 0.004 respectively). The results of this pilot study are encouraging however a more extensive study is required to determine if Jordanian radiographers are capable of successfully taking part in breast screen reading. The lack of skills and knowledge required for correct and consistent reporting of high-MD images highlights the need for any formal training in mammographic interpretation to focus on the dense breast.

Abstract: Background: Radiologists are at higher risk of adverse health effects due to their occupational radiation exposure therefore, applying protection techniques is imperative. Studies on radiologists’ compliance in this regard are scarce. We aimed to assess compliance with radiation safety practices among radiologists. Methods: Questionnaires were distributed to radiologists in tertiary hospitals. The questionnaire was designed to assess compliance in three domains: using personal protective devices, using exposure-reduction techniques during fluoroscopic exposures, and using personal dose-monitoring devices. Descriptive analysis of the compliance was performed. Results: Sixty-two radiologists were included in the analysis. Use of leaded aprons and thyroid shields was commonplace, whereas only 3.2% ever use leaded eyeglasses. About half of the radiologists always considered reducing the time of exposure and avoided exposure by the primary beam, and the other half did that sometimes. Most of the radiologists (66.1%) always complied with reducing the number of unnecessary exposures, and the rest only complied sometimes. Most of the radiologists (93.5%) always used single personal dose-monitoring devices, most commonly at the neck level over the collar. There was no difference in compliance between different sexes, position descriptions, hospital types, hospital sizes, or years of experience. Conclusion: Future compliance improvement strategies for radiologists should focus on use of thyroid shields and leaded eyeglasses and use of exposure-reduction techniques during fluoroscopic operations.

Abstract: To investigate the impact of breast density on the performance of radiologists when mammograms are digitally acquired and displayed. A total of 150 craniocaudal digital mammograms including 75 cases with cancer were examined by 14 radiologists ided into two groups: those who read more (six) and less (eight) than 2000 mammograms per year. Cases were classified as low or high mammographic density. For both types of cases, detection of cancers within and outside the dense fibroglandular tissue was investigated. The performance of radiologist was measured using jack-knife free-response receiver operating characteristic (JAFROC) figure of merit (FOM). Radiologists with over 2000 annual reads had significantly higher JAFROC FOM (P = .03) for high (0.76) mammographic density compared to low (0.70) mammographic density cases. When lesions overlaid the fibroglandular tissue, cases with high mammographic density compared to low mammographic density displayed increased location sensitivity for all radiologists (P = .03) and for those radiologists reading more than 2000 mammograms annually (P = .04), whereas JAFROC FOMs increased for all radiologists (P = .05). No significant changes were observed when the lesion was outside the fibroglandular region. Increased mammographic density improves the performance of experienced radiologists when using digital mammograms. This finding, which does not align with those previously reported for film screen systems, may be because of windowing/leveling opportunities available with digital images.

Abstract: The low subject contrast between cancerous and fibroglandular tissue could obscure breast abnormalities. To investigate radiologists’ performance for detection of breast cancer in low and high mammographic density (MD) when cases are digitally acquired. A test set of 60 digital mammography cases, of which 20 were cancerous, were examined by 17 radiologists. Mammograms were categorized as low (≤50%) or high ( %) MD and rated for suspicion of malignancy using the Royal Australian and New Zealand College of Radiology (RANZCR) classification system. Radiologist demographics including cases read per year, age, subspecialty, and years of reporting were recorded. Radiologist performance was analyzed by the following metrics: sensitivity specificity area under the receiver operating characteristic (ROC) curve (AUC), location sensitivity, and jackknife free-response ROC (JAFROC) figure of merit (FOM). Comparing high to low MD cases, radiologists showed a significantly higher sensitivity ( P = 0.015), AUC ( P = 0.003), location sensitivity ( P = 0.002), and JAFROC FOM ( P = 0.001). In high compared to low MD cases, radiologists with annual reads and radiologists with no mammographic subspecialty had significantly higher AUC, location sensitivity, and JAFROC FOM. Radiologists with ≥1000 annual reads and radiologists with mammography subspecialty demonstrated a significant increase in location sensitivity in high compared to low MD cases. In this experimental situation, radiologists’ performance was higher when reading cases with high compared to low MD. Experienced radiologists were able to precisely localize lesions in breasts with higher MD. Further studies in unselected screening materials are needed to verify the results.

Abstract: Effective detection of breast cancer using mammography is an important public health issue worldwide. Breasts that contain higher levels of fibroglandular compared with fatty tissue increase breast radio-opacity making it more difficult to differentiate between normal and abnormal findings. The higher prevalence of breast cancer amongst women with denser breasts demands the origination of effective solutions to manage this common radiographic appearance. This brief review considers the impact of higher levels of density on cancer detection and the importance of digital technology in possibly reducing the negative effects of increased density.
