Radiology program director's perspective on a novel hands-on advanced elective.

With the advent of the USMLE Step 1 exam moving to a pass/fail status, Radiology Program Directors (PDs) and Associate Program Directors (APDs) need alternative methods of identifying interested and engaged medical students who are applying to their program. Additionally, undergraduate radiology medical education in the United States varies widely from institution to institution with no universal mandatory radiology component. To address these problems, we implemented an advanced fourth year hands-on radiology elective where the students were treated as first year radiology residents (R1s), giving them resident-level access to the Picture Archive and Communication System (PACS) and dictation software, and allowing them to perform entry-level procedures with appropriate supervision. After implementation of the elective, a 5-question online survey was sent to two hundred and ninety-eight PDs and APDs via the Association of Program Directors in Radiology (APDR) listserv, of which seventy-two responses were compiled, yielding a response rate of 24%. The survey focused on how a hands-on medical student elective would help in assessing prospective candidates and predicting R1 performance. Most respondents felt interest in radiology, motivation, and interpersonal skills would be better assessed after such an elective and the vast majority felt hands-on Advanced Elective would be at least slightly predictive of first year resident performance. Based on this information, we believe implementing a hands-on advanced radiology elective would significantly help address the passive nature of traditional radiology electives, providing valuable information to PDs and APDs and giving the best possible radiology experience to our medical students.

Radiology podcasting as a model for asynchronous remote learning in the COVID-19 era.

RATIONALE AND OBJECTIVES: We aimed to create an open access online radiology podcast to educate listeners at any time, from anywhere. To meet learner needs and improve the likelihood of successful implementation and utilization, we assessed radiology trainee attitudes and experiences of podcasts. MATERIALS AND METHODS: We developed an educational podcast, From the Viewbox, focused on evergreen themes and practical approaches to radiology. Content categories included Diagnostic Approach, Specific Imaging Diagnoses, Noninterpretive Skills, and Special Topics. We released and promoted episodes on multiple digital platforms. Radiology trainees were surveyed and data were analyzed to assess listener preferences and usage trends. RESULTS: Only 19% of our trainees had previously listened to a radiology podcast, yet 81% expressed interest in listening routinely. After initial release, 86% of trainees listened to the podcast and 62% listened routinely. Episodes gained the most plays immediately following release but retained and continued to attract more listeners. The most popular episode discussing COVID-19 diagnosis and imaging, emphasized the importance of selecting high yield content to match listener needs. Most trainees felt the podcast had "very high" or "high" value in educational value, accessibility, and time efficiency. CONCLUSIONS: From the Viewbox offers efficient and accessible audio-only learning modules that can be used independently or effectively paired with traditional resources to decrease barriers in radiology education and enhance learner productivity. Podcasting is an underutilized asynchronous remote learning tool that can help overcome current challenges of social distancing, and more importantly address the diverse preferences and needs of our learners.

Implementation of a Novel Hands-on Advanced Radiology Elective.

Despite the use of imaging in many medical and surgical practices, no universal mandatory radiology component is required by the Liaison Committee on Medical Education. In contrast, United States medical students are required to complete at least one core subinternship during their final year of medical school in medicine, surgery, pediatrics, or family medicine, regardless of their chosen field of interest. Students are expected to perform just below the level of an intern, performing functions such as assisting in writing notes, placing orders, and arranging for appropriate follow-up. To our knowledge, there are few institutions that offer a comparable clinical experience in radiology. In order to address this, we successfully designed and implemented a hands-on medical student advanced radiology elective, which allowed for experiential learning through independent dictation of radiographic examinations and procedure-based practice. Here, we describe the process of developing such an elective, how to implement it at other institutions, and some insight into troubleshooting any potential pitfalls should they arise. Overall, our novel hands-on elective enables a more student-centered, active learning approach, allowing for more in-depth, accurate evaluation of specialty choice while also equipping faculty and residency programs with the skills to best assess student interest, motivation, knowledge, and communication skills.

Abbreviated MRI of the foot in patients with suspected osteomyelitis.

PURPOSE: To determine the diagnostic accuracy of an abbreviated magnetic resonance imaging (MRI) protocol of the foot for the diagnosis of osteomyelitis in patients with acute foot infection. METHODS: This retrospective study evaluated adult patients (age 18 and over) visiting an academic medical center from 1 January 2013 to 31 December 2015 who were imaged with MRI for suspected acute pedal osteomyelitis. Examinations were performed utilizing the departmental standard protocol. All examinations were retrospectively interpreted by five radiologists under two protocols: a reference standard protocol consisting of all non-contrast sequences obtained at initial acquisition and an abbreviated protocol consisting of only coronal T1-weighted and sagittal T2-weighted fast multiplanar inversion-recovery (FMPIR) sequences. Interpretation of the two imaging subsets was separated in time by at least 6 weeks for each reader. Each examination was assigned a score to represent one of four diagnostic categories: normal; soft tissue infection without bone changes or bone changes specific to a non-infectious etiology; nonspecific bone marrow changes; or bone changes specific for osteomyelitis. Diagnostic accuracy of both protocols was determined based on clinical diagnosis and treatment of osteomyelitis, and histopathology when available. RESULTS: One hundred and two MRI examinations met inclusion criteria; participants ranged in age from 26 to 91 years, with a mean age of 59 years. Seventy examinations were performed for male participants (69%) and 32 for female participants (31%). Thirty-five had a confirmed diagnosis of osteomyelitis, while the remainder (n = 67) did not. An average of 6 non-contrast sequences was performed during each examination. The most common protocol (53/102 examinations) was comprised of the following 6 sequences: axial T1-weighted, axial fat-saturated proton density, sagittal T1-weighted, sagittal T2-weighted FMPIR, coronal T1-weighted, and coronal fat-saturated proton density. After patient positioning, the abbreviated protocol sequences (sagittal T2-weighted FMPIR and coronal T1-weighted) were performed in an average total of 8 min. The reference standard protocol required an average of 22 min to complete 6 sequences. Averaged across all readers, the AUC for the reference standard full protocol and the abbreviated protocols were 0.843 and 0.873, respectively. The difference in AUC between protocols was not statistically significant (p = 0.1297), with the abbreviated protocol showing a non-significantly greater AUC. CONCLUSIONS: An abbreviated MRI protocol, including only coronal T1-weighted and sagittal T2-weighted FMPIR images, is non-inferior to standard MRI protocol for the diagnosis of acute pedal osteomyelitis. It should be considered as a diagnostic alternative for reducing imaging time and improving patient access to MRI.

Soft Tissue Injuries of the Finger and Thumb.

Soft tissue digital injury of the hand is a common presenting complaint in the emergency setting. Although initial work-up requires physical examination and radiographs, many of these entities may be radiographically occult and solely appreciated on ultrasound (US) or magnetic resonance imaging (MRI). If undiagnosed, these conditions may lead to sequela of untreated disease including early osteoarthritis, pain, permanent deformity, and immobility. Soft tissue finger injuries that may not be readily apparent without the use of MRI or US are discussed. The key imaging features of radiolucent foreign bodies in addition to tendon, collateral ligament, sagittal band, and pulley injuries on MRI and US are discussed.
