Well-crafted multiple-choice questions are one proven method of testing a learner's understanding of a specific topic. The authors provide readers with rules that must be followed to create high-quality multiple-choice questions. Common question writing mistakes are also addressed to assist readers in improving their item-writing skills.

Just as importantly, radiology educators benefit academically and professionally when they demonstrate a portfolio of published scholarship to promotion committees and department leaders. The principles and techniques used in the design of medical education research are not well understood by many radiology educators because educational scholarship methodologies have received little attention in our literature. Lack of familiarity and inexperience with research methodologies, particularly qualitative research, are barriers that education researchers can address with knowledge acquisition and practice. This overview surveys the landscape and offers suggested medical education research resources to help researchers explore topics to increase understanding of quantitative, qualitative, mixedmethods, survey, and educational design methodologies.

Methods: In 2013 and 2014, medical students attended a dedicated 1-week radiology clerkship course. In 2015, the block clerkship model for radiology transitioned to a vertically integrated curriculum. By 2019, radiology content was integrated into many of the health illness and disease course blocks. Pre-and postcourse multiple-choice question tests as well as anonymous surveys were administered for both clerkship and integrated curriculum blocks. The student survey questions assessed perceptions regarding interpretation skills, imaging modality knowledge, and radiologists' roles. Results: Among 197 total students in the clerkship block, surveys were completed by 170 respondents, yielding a response rate of 86.3%. Among 106 students in the longitudinal course, surveys were completed by 71 respondents, yielding a response rate of 67%. For both clerkship and longitudinally integrated courses, the average number of correct responses after completion of the courses was significantly greater than the average number of correct precourse responses. Compared with students in the clerkship block curriculum, students in the longitudinal curriculum demonstrated a significantly greater frequency of agreement in response to survey questions regarding significant exposure to radiology, feeling comfortable interpreting CT images, and being familiar with how to use the ACR Appropriateness Criteria. Conclusions: Transitioning from a single clerkship block to a more integrated format allows a more effective patient-centered clinical approach to medical imaging.

Despite established needs for increased quality and quantity of radiology physics resources, there is little information regarding the most effective method of engaging learners and delivering this content. Methods: To assess trainee perceptions of currently available MRI physics learning resources, a needs assessment survey was distributed to current members and recent graduates of our diagnostic radiology residency program. Based on the results of the needs assessment, we created three different types of media illustrating the fundamentals of MRI physics: text with images, text with animations, and a narrated video. Formal evaluation of the media via an institutional review board-approved, experimentally designed study helped us better understand the impact that media format had on deep structure learning, efficiency, and engagement. Results: Respondents to the needs assessment indicated a desire for physics resources that were visually appealing with simplified details and associated practice questions. Participants demonstrated significant learning across all media formats but rated video as the most engaging media type. Conclusion: Knowledge of media attributes that positively impact trainee performance may inform content creators and educators alike when designing and distributing educational materials related to MRI physics.

Inferior vena cava filters (IVCFs) are considered for patients with absolute contraindications or failures of anticoagulation. However, studies examining the population-based disparities of IVCF placement and retrieval are limited. The association between patient and clinical characteristics in the likelihood of and time to IVCF placement and retrievals in a nationally representative cohort was examined. Methods: Medicare patients aged > 65 years with index VTE claims between 2015 and 2018 were followed through 2019 to identify IVCF placements and retrievals. Rates were compared using survival analysis methods. Results: Of the 516,978 patients with VTE diagnoses, 5,864 (1.1%) had IVCFs placed, and 1,884 (32.1%) of those underwent retrieval procedures. Placement and retrieval rates varied significantly by demographics, comorbidity burden, and geographic region. From Cox regression, older age (hazard ratio [HR], 1.26; P < .0001), higher baseline comorbidity (Elixhauser) score (HR, 1.07; P < .0001), and outpatient (vs inpatient) site of VTE service (HR, 2.11; P < .0001) were associated with increased frequency of IVCF placement. The rate of retrieval was significantly lower for men (HR, 0.83; P = .0393), patients with higher comorbidity scores (HR, 0.95; P = .0037), and those with outpatient (vs inpatient) VTE sites of service (HR, 0.77; P = .0173). Neither facility-nor county-level characteristics were significantly associated with placements or retrievals. Conclusions: This large cohort of Medicare beneficiaries with newly diagnosed VTE demonstrated inequities in IVCF placement and retrieval.

Methods: The in-hospital costs of PAE and TURP in the United States were obtained from a recent cost analysis. Clinical outcomes including nature and rate of adverse events for TURP and PAE along with rates of retreatment because of complications or clinical failure were obtained from peer-reviewed literature. A decision tree-based Markov model was created, analyzing long-term cost-effectiveness for TURP and PAE from a US health care sector perspective. Cost-effectiveness over a time frame of 5 years was estimated while assuming a willingness to pay of $50,000 per quality-adjusted life-year (QALY). The primary outcome was incremental cost-effectiveness ratio. Results: PAE resulted in overall cost of $6,464.92 and an expected outcome of 4.566 QALYs. In comparison, TURP cost $9,221.09 and resulted in expected outcome of 4.577 QALYs per treatment. The incremental cost-effectiveness ratio for TURP was $247,732.65 per QALY. On the basis of the willingness-to-pay threshold, PAE is cost effective compared with TURP. Conclusions: On the basis of our model, PAE in comparison with TURP can be regarded as a cost-effective treatment option for patients with lower urinary tract symptoms within the US health care system.
