Abstract
OBJECTIVE To determine the rate of lymphoproliferative disease (LPD) in women undergoing routine breast cancer screening (BCS). BCS can reveal pathologies other than carcinoma that involve the breast and lymph tissue. The few studies that have described cases in which BCS led to the diagnosis of LPD were based on small series and focused on imaging rather than clinical characteristics. SETTING AND METHODS A multi-center retrospective study in Israel, investigating LPD rate and characteristics among women diagnosed with LPD via BCS. RESULTS Thirty-four patients out of 14,400 consecutive women undergoing BCS at Tel Aviv Sourasky Medical Center during the study period were diagnosed with LPD, suggesting a diagnosis rate of 0.24%. The enlarged cohort (n = 45), including 11 patients that were retrieved from the databases of three other centers, demonstrates a predominant histological diagnosis of non-aggressive LPD (n = 33). Thirty-four (76%) had a suspicious axillary lymph node, and 11 had a breast lesion. The median maximal lesion size was 1.95 cm (range 0.8-6.5). Disease was localized in 60% of patients (stage 1 and 1E). Univariate analysis revealed that lymphocyte count was inversely associated with aggressive histology. At median follow-up of 39 months, all but three patients were alive. These three had been diagnosed with non-aggressive LPD which had never been treated and died from unrelated causes. CONCLUSIONS The LPD detection rate via BCS was 2.36 per 1000 screens. The majority of LPDs were non-aggressive. Nearly a third were aggressive, most detected at an early stage, and the clinical outcome was generally favorable.

Abstract
Background: Variations in the performance of radiologists reading mammographic images are well reported, but key parameters explaining such variations in different countries are not fully explored. The main aim of this study is to investigate performances of Chinese (Hong Kong SAR and Guangdong Province) and Australian radiologists in interpreting dense breast mammographic images. Methods: A test set, contained 60 mammographic examinations with high breast density, was used to assess radiologists’ performance. Twelve Chinese and thirteen Australian radiologists read all the cases independently and were asked to identify all lesions and provide a grade from 1 to 5 to each lesion. Case sensitivity, specificity, lesion sensitivity, AUC and JAFROC were used to assess radiologists’ performances. Demographic information and reading experience were also collected from the readers. Performance scores were compared between the two populations and the relationships between performance scores and their reading experience were discovered. Results: For radiologists who were less than 40-year-old, lesion sensitivity, AUC and JAFROC were significantly lower in Chinese radiologists than those in Australian (52.10% vs 71.45%, p=0.043; 0.76 vs 0.84, p=0.031; 0.59 vs 0.72, p=0.045; respectively). Australian radiologists with less than 10 years of reading experience had higher AUC and JAFROC scores compared with their Chinese counterparts (0.83 vs 0.76, p=0.039; 0.70 vs 0.56, p=0.020, respectively). Conclusions: We found that younger Australian radiologists performed better at reading dense breast cases which is likely to be linked to intensive fellowship training, immersion in a screening program and exposure to the benefits of a performance-measuring education tool.

J Am Coll Radiol 2019; 16:1528-1546. [PMID: 31247156 DOI: 10.1016/j.jacr.2019.04.016] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2018] [Revised: 04/23/2019] [Accepted: 04/23/2019] [Indexed: 10/26/2022]
Abstract
PURPOSE The authors evaluate whether supplemental training for radiologists improves their breast screening performance and how this is measured. METHODS A systematic search was conducted in PubMed on August 3, 2017. Articles were included if they described supplemental training for radiologists reading mammograms to improve their breast screening performance and at least one outcome measure was reported. Study quality was assessed using the Medical Education Research Study Quality Instrument. RESULTS Of 2,199 identified articles, 18 were included, of which 17 showed improvement on at least one of the outcome measures, for at least one training activity or subgroup. Two measurement approaches were found. For the first approach, measuring performance on test sets, sensitivity, and specificity were the most reported outcomes (8 of 11 studies). Recall rate is the most reported outcome (6 of 7 studies) for the second approach, which measures performance in actual screening practice. The studies were mainly of moderate quality (Medical Education Research Study Quality Instrument score 11.7 ± 1.7), caused by small sample sizes and the lack of a control group. CONCLUSIONS Supplemental training helps radiologists improve their screening performance, despite the mainly moderate quality of the studies. There is a need for better designed studies. Future studies should focus on performance in actual screening practice and should look for methods to isolate the training effect. If test sets are used, focus should be on knowledge about correlation between performance on test sets and actual screening practice.

Abstract
Background: Breast cancer, is increasing in prevalence amongst South East (SE) Asian women, highlighting the
need for high quality, early diagnoses. This study investigated radiologists’ detection efficacy in a developing (DC)
and developed (DDC) SE Asian country, as compared to Australian radiologists. Methods: Using a test-set of 60
mammographic cases, 20 containing cancer, JAFROC figures of merit (FOM) and ROC area under the curves (AUC)
were calculated as well as location sensitivity, sensitivity and specificity. The test set was examined by 35, 15, and
53 radiologists from DC, a DDC and Australia, respectively. Results: DC radiologists, compared to both groups of
counterparts, demonstrated significantly lower JAFROC FOM, ROC AUC and specificity scores. DC radiologists had
a significantly lower location sensitivity than Australian radiologists. DC radiologists also demonstrated significantly
lower values for age, hours of reading per week, and years of mammography experience when compared with other
radiologists. Conclusion: Significant differences in breast cancer detection parameters can be attributed to the experience
of DC radiologists. The development of inexpensive, innovative, interactive training programs are discussed. This nonuniform
level of breast cancer detection between countries must be addressed to achieve the World Health Organisation
goal of health equity.

Performance of an Interactive Upper Extremity Peripheral Nerve Training Module Among Medical Students, Radiology Residents, and Fellows: A Multi-institutional Study. Curr Probl Diagn Radiol 2019; 49:7-11. [PMID: 30639073 DOI: 10.1067/j.cpradiol.2018.12.011] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2018] [Revised: 12/27/2018] [Accepted: 12/31/2018] [Indexed: 12/27/2022]
Abstract
BACKGROUND AND PURPOSE Chronic pain is a common problem and imaging is becoming increasingly utilized in the characterization of peripheral neuropathy, although this topic is not emphasized during medical training. We hypothesized that an electronic module and nerve atlas would be effective in improving comprehension among trainees. MATERIALS AND METHODS In this IRB-approved study, a training module was created that included a side-by-side comparison of normal upper extremity nerves on magnetic resonance imaging and ultrasound (US), with embedded questions and cases, followed by a brief hands-on US scanning session. Thirty volunteers with variable training were enrolled in 1 institution, while 14 volunteers were enrolled in another. Pre- and post-test scores were collected and compared. RESULTS There was a response rate of 100% at both institutions. At the first institution, subjects were divided into 2 groups: group 1 (16 medical students) and group 2 (14 residents/fellows). There was a baseline deficit of knowledge among both groups, with a mean pretest score of 37.5% and 47.5% for group 1 and group 2, respectively (P = 0.017). After module completion, both groups improved with a mean post-test score of 67.2% for group 1 and 76.1% for group 2. At the second institution, there was similar improvement even if the scanning session was not done. CONCLUSIONS Use of an electronic module helps trainees to become more familiar with peripheral nerve imaging, regardless of level of training. Use of the module, even in the absence of hands-on US scanning, results in an improved understanding of this topic.

Abstract
The millennial generation consists of today's medical students, radiology residents, fellows, and junior staff. Millennials' comfort with immersive technology, high expectations for success, and desire for constant feedback differentiate them from previous generations. Drawing from an author's experiences through radiology residency and fellowship as a millennial, from published literature, and from the mentorship of a long-time radiology educator, this article explores educational strategies that embrace these characteristics to engage today's youngest generation both in and out of the reading room.

Abstract
RATIONALE AND OBJECTIVES Despite their increasing prevalence, online textbooks, question banks, and digital references focus primarily on explicit knowledge. Implicit skills such as abnormality detection require repeated practice on clinical service and have few digital substitutes. Using mechanics traditionally deployed in video games such as clearly defined goals, rapid-fire levels, and narrow time constraints may be an effective way to teach implicit skills. MATERIALS AND METHODS We created a freely available, online module to evaluate the ability of individuals to differentiate between normal and abnormal chest radiographs by implementing mechanics, including instantaneous feedback, rapid-fire cases, and 15-second timers. Volunteer subjects completed the modules and were separated based on formal experience with chest radiography. Performance between training and testing sets were measured for each group, and a survey was administered after each session. RESULTS The module contained 74 cases and took approximately 20 minutes to complete. Thirty-two cases were normal radiographs and 56 cases were abnormal. Of the 60 volunteers recruited, 25 were "never trained" and 35 were "previously trained." "Never trained" users scored 21.9 out of 37 during training and 24.0 out of 37 during testing (59.1% vs 64.9%, P value <.001). "Previously trained" users scored 28.0 out of 37 during training and 28.3 out of 37 during testing phases (75.6% vs 76.4%, P value = .56). Survey results showed that 87% of all subjects agreed the module is an efficient way of learning, and 83% agreed the rapid-fire module is valuable for medical students. CONCLUSIONS A gamified online module may improve the abnormality detection rates of novice interpreters of chest radiography, although experienced interpreters are less likely to derive similar benefits. Users reviewed the educational module favorably.

Abstract
PURPOSE To establish the effect on diagnostic confidence of a simulation setting, in which radiologists re-interpret anonymized pediatric MRI cases. MATERIALS In this IRB-approved study, participants completed surveys rating confidence before and after interpreting 10 MRI cases for suspected appendicitis in children. RESULTS 18 radiologists (4 faculty, 5 fellows, and 9 residents) correctly identified an average of 7.44 cases (range 5-9). Self-described confidence regarding technique and interpretation increased from 2.0 (SD 0.77) and 2.33 (SD 0.69) to 2.83 (SD 0.71) and 2.94 (SD 0.73), respectively. CONCLUSION Simulated interpretation of pediatric MRI in suspected appendicitis results in increased self-describe confidence without requiring additional capital/equipment expenses.
