The Big Squeeze: Factors Contributing to Moral Distress Among Radiologist Clinician-Educators.

Moral distress is a term used to describe the cognitive-emotional dissonance that is experienced when one is compelled to act contrary to one's moral requirements. This occurs as a result of systemic constraints that prevent an individual from taking actions that they perceive as morally right, resulting in a perceived violation of one's core values and duties. There has been a growing interest in the prevalence of moral distress in healthcare, particularly as a root cause of burnout. A recent national survey on moral distress in radiology found that 98% of respondents experienced at least some degree of moral distress with 18% of respondents having left a position due to moral distress. One of the scenarios associated with the highest degree of moral distress related to the conflict that arises when one feels unable to fulfill teaching responsibilities due to high clinical demands. Now more than ever, clinician-educators are asked to do more with less time, fewer resources, and in an increasingly demanding work environment that is often discordant with providing quality education to their learners. In this manuscript, we aim to discuss the factors contributing to moral distress in radiologist clinician-educators as a framework to better understand the implications of these drivers, and to offer our perspective on potential mitigating measures.

Imaging assessment of spine infection.

This article comprehensively reviews current imaging concepts in spinal infection with primary focus on infectious spondylodiscitis (IS) as well as the less common entity of facet joint septic arthritis (FSA). This review encompasses the multimodality imaging appearances (radiographs, CT, MRI, and nuclear imaging) of spinal infection-both at initial presentation and during treatment-to aid the radiologist in guiding diagnosis and successful management. We discuss the pathophysiology of spinal infection in various patient populations (including the non-instrumented and postoperative spine) as well as the role of imaging-guided biopsy. We also highlight several non-infectious entities that can mimic IS (both clinically and radiologically) that should be considered during image interpretation to avoid misdiagnosis. These potential mimics include the following: Modic type 1 degenerative changes, acute Schmorl's node, neuropathic spondyloarthropathy, radiation osteitis, and inflammatory spondyloarthropathy (SAPHO syndrome).

Using Rubrics to Evaluate E-Learning Tools in Radiology Education.

Recent trends in medical education with an emphasis on active learning strategies and blended learning techniques have resulted in a growing volume and utilization of online educational resources. Integration of online learning tools into medical curricula has been further necessitated during the COVID-19 pandemic. With access to abundant digital radiology education resources, it has become increasingly important for educators to be able to evaluate the efficacy of e-learning tools for use in radiology education. In this manuscript, the authors describe their successful search for a vetted method to evaluate e-learning tools in radiology education. The selected rubric was designed by educational developers supporting technology to be used as a formative tool in higher education. The rubric was applied in condensed and noncondensed formats to 2 existing popular highly subscribed radiology e-learning resources and results were displayed in narrative and visual formats. More widespread application of this rubric would be beneficial to the content creators and learners alike.

ACR Appropriateness Criteria® Chronic Elbow Pain.

Chronic elbow pain can be osseous, soft tissue, cartilaginous, and nerve related in etiology. Imaging plays an important role in differentiating between these causes of chronic elbow pain. This document provides recommendations for imaging of chronic elbow pain in adult patients. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer-reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances in which peer-reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.

ACR Appropriateness Criteria® Osteonecrosis: 2022 Update.

Osteonecrosis is defined as bone death due to inadequate vascular supply. It is sometimes also called "avascular necrosis" and "aseptic necrosis" when involving epiphysis, or "bone infarct" when involving metadiaphysis. Common sites include femoral head, humeral head, tibial metadiaphysis, femoral metadiaphysis, scaphoid, lunate, and talus. Osteonecrosis is thought to be a common condition most commonly affecting adults in third to fifth decades of life. Risk factors for osteonecrosis are numerous and include trauma, corticosteroid therapy, alcohol use, HIV, lymphoma/leukemia, blood dyscrasias, chemotherapy, radiation therapy, Gaucher disease, and Caisson disease. Epiphyseal osteonecrosis can lead to subchondral fracture and secondary osteoarthritis whereas metadiaphyseal cases do not, likely explaining their lack of long-term sequelae. Early diagnosis of osteonecrosis is important: 1) to exclude other causes of patient's pain and 2) to allow for possible early surgical prevention to prevent articular collapse and need for joint replacements. Imaging is also important for preoperative planning. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer-reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence.

Current Imaging Concepts in Shoulder and Hip Arthroplasty.

Primary joint replacements are increasingly being performed, likely owing to our aging population and improved techniques. Advances have been made in shoulder joint replacements including development of cuff tear arthroplasty hemiarthroplasty, improvements to reverse total shoulder arthroplasty designs, and more detailed preoperative imaging. The importance of spinopelvic kinematics has been brought to light in hip joint replacements. Appropriate preoperative measurement and subsequent compensation for the malalignment are critical.

Medical student education in the time of COVID-19: A virtual solution to the introductory radiology elective.

RATIONALE AND OBJECTIVES: During the COVID-19 pandemic, medical educators and students are facing unprecedented challenges while navigating the new virtual landscape that social-distancing policies mandate. In response to these challenges, a new virtual introduction to radiology elective was established with unique online resources and curriculum. MATERIALS AND METHODS: A previously in-person 2-week introductory radiology elective was converted into a completely virtual experience using an internally developed, open-source, peer-reviewed, web-based teaching modules combined with virtual lectures, interdisciplinary conferences, and readout sessions of de-identified cases loaded to a DICOM viewer. Students from the first four months of course enrollment completed a multiple choice pre- and post-course knowledge assessments and a 5-point Likert Scale survey as part of their educational experience. RESULTS: In total, 26 4th-year medical students participated over 4 separate 2-week sessions from July to October of 2020. This included 12 students from the home intuition and 14 visiting students. On average, students scored 62.2% on the 55-question pre-test and 89.0% on the same test upon completion of the course, a statistically significant increase (p < 0.001). All 26 students felt engaged throughout the course. All 26 agreed (23 "strongly agreed") that they were more comfortable looking at imaging studies following the course. All 26 also agreed (21 "strongly agreed") that the course helped them prepare for their future clinical rotations and careers. CONCLUSION: Initial pilot program using unique web-based resources and student encounters during a two-week virtual introductory radiology elective proved to be a positive educational experience for the first 26 students enrolled.

ACR Appropriateness Criteria® Acute Trauma to the Ankle.

Acute injuries to the ankle are frequently encountered in the setting of the emergency room, sport, and general practice. This ACR Appropriateness Criteria defines best practices for imaging evaluation for several variants of patients presenting with acute ankle trauma. The variants include scenarios when Ottawa Rules can be evaluated, when there are exclusionary criteria, when Ottawa Rules cannot be evaluated, as well as specific injuries. Clinical scenarios are followed by the imaging choices and their appropriateness with an accompanying narrative explanation to help physicians to order the most appropriate imaging test. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Concomitant calciphylaxis and COVID-19 associated thrombotic retiform purpura.

While initial reports regarding coronavirus disease 2019 (COVID-19) focused on its pulmonary manifestations, more recent literature describes multisystem abnormalities related to its associated microvascular angiopathy. Calciphylaxis is a rare systemic condition characterized by tissue necrosis in the setting of systemic microvascular calcifications. Both COVID-19 and calciphylaxis are procoagulant diagnoses associated with vascular-mediated cutaneous findings. To our knowledge, this is the first report to document the coexistence of COVID-19 associated retiform thrombotic purpura and calciphylaxis in a single patient, to link the pathologic etiologies of the two entities, and to describe the concomitant diagnoses' associated radiologic findings.

ACR Appropriateness Criteria® Acute Trauma to the Knee.

Acute trauma to the knee is a common presentation seen in the emergency department. After a routine clinical examination, imaging is frequently performed to facilitate the diagnosis and almost always starts with radiographs. If clinically indicated, advanced cross-sectional imaging may then be performed for further evaluation. CT is often performed for preoperative planning of the complex tibial plateau and distal femur fractures. Currently, MRI is the study of choice for evaluation of bone marrow, internal derangements, and other soft-tissue injuries about the knee joint. In patients with knee dislocations, MR angiography may be performed simultaneously with MRI for evaluation of internal derangements and vascular injuries with less morbidity compared to conventional angiography. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Pediatric ankle injuries: utilizing the Dias-Tachdjian classification.

Pediatric ankle injuries require timely diagnosis due to their involvement of the distal tibial physis and subsequent impact on long bone growth. These injuries occur in a predictable pattern based on ankle position, direction of force, and degree of closure of the distal tibial physis. The Dias-Tachdjian classification describes possible ankle injury patterns for the completely open physis, and we present a simplified algorithm for applying this system in routine radiographic interpretation. Similar to the Lauge-Hansen classification in adults, the Dias-Tachdjian system is based on the position of the foot and direction of force at the time of injury with four major patterns: supination-inversion, pronation-eversion external rotation, supination-plantar flexion, and supination-external rotation. In addition, we examine the effect that the closing distal tibial physis has on adolescent fracture patterns (specifically, Tillaux and triplane fractures). Awareness of these injury patterns helps the radiologist to identify nondisplaced fractures and subtle physeal injuries with implications for surgical and/or conservative management.

Current Fixation Options for Elbow, Forearm, Wrist, and Hand Fractures.

The universal goals of upper limb fracture management are to restore anatomic alignment, establish stable fracture fixation (while preserving blood supply), and allow for early mobilization of the elbow, wrist, and digits. However, the indications for operative management and fixation constructs are specific to each fracture type. This article systematically reviews current classifications and treatment options for adult fractures of the distal humerus, radius, ulna, scaphoid, metacarpals, and phalanges. For each anatomic location, we discuss the salient imaging features to guide management decisions (conservative versus internal and/or external fixation). Specifically, we emphasize the amount of displacement, angulation, comminution, and/or intra-articular involvement typically guiding operative management for each fracture type. Through this understanding of the surgical indications, rationale behind different fixation options, and common complications, the radiologist can better support the orthopaedic surgeon via more informed fracture reporting.

Radiologic evaluation of fracture healing.

While assessment of fracture healing is a common task for both orthopedic surgeons and radiologists, it remains challenging due to a lack of consensus on imaging and clinical criteria as well as the lack of a true gold standard. Further complicating this evaluation are the wide variations between patients, specific fracture sites, and fracture patterns. Research into the mechanical properties of bone and the process of bone healing has helped to guide the evaluation of fracture union. Development of standardized scoring systems and identification of specific radiologic signs have further clarified the radiologist's role in this process. This article reviews these scoring systems and signs with regard to the biomechanical basis of fracture healing. We present the utility and limitations of current techniques used to assess fracture union as well as newer methods and potential future directions for this field.

A CT-based approach with 3D modeling to determine optimal radiographic views of the scaphotrapezial and scaphotrapezoid joints.

PURPOSE: To use a CT-based approach with 3D modeling to determine novel radiographic views of the scaphotrapezial (STl) and scaphotrapezoid (STd) joints. MATERIALS AND METHODS: Consecutive wrist CT scans excluding those with pathology of the distal radius, scaphoid, trapezium, or trapezoid of subjects between ages 18 and 60 years were retrospectively reviewed. Three-dimensional reconstructions of CT scans were created and best-fit planes of the STl and STd joints were generated. Angles of these planes relative to a distal radial coordinate system were calculated to determine tilt of the wrist and the X-ray beam for novel radiographic views of these joints. RESULTS: Fifty eligible wrist CT scans were identified. The mean age was 38 years (range, 18 to 59). For the novel STl PA view, the wrist is supinated 17° from the standard PA view and the X-ray beam is canted 6° caudad. In the STl lateral view, the wrist is pronated 17° from the standard lateral view, and the X-ray beam is canted 20° caudad. In the STd PA tilt view, the wrist is supinated 28° from the standard PA view, and the X-ray beam is canted 13° caudad. In the STd joint lateral tilt view, the wrist is pronated 28° from the standard lateral view, and the X-ray beam is canted 29° caudad. CONCLUSION: We describe novel radiographic views of the STl and STd joints based on 3D modeling of wrist CT scans. Further studies are required to assess the efficacy of these views in detecting joint pathology.

SMA-like syndrome with variant mesenteric venous anatomy.

Superior mesenteric artery (SMA) syndrome refers to the constellation of symptoms that are associated with intermittent obstruction of the duodenum due to vascular compression. We present a case of SMA-like syndrome related to variant mesenteric venous drainage in the setting of normal aortomesenteric angle (AMA) and borderline reduced aortomesenteric distance (AMD).

Giant Cell Tumor of Distal Radius After Open Reduction Internal Fixation for Distal Radius Fracture.

CASE: A 77-year-old woman presented with volar wrist pain 1.5 years after undergoing distal radius volar locked plating for fracture. Radiographs and CT were notable only for plate prominence, and she was admitted for removal of hardware. Intraoperatively, a large cavitary bone lesion was found. Histopathology demonstrated a giant cell tumor of the bone. Definitive management consisted of wide en bloc resection and osteoarticular allograft reconstruction, which achieved local control and an acceptable clinical result. CONCLUSION: Although not previously described, a giant cell tumor of the bone may develop after fracture. Metal artifact in an area of previous internal fixation can make recognition challenging, but dual-energy CT can be used to decrease this artifact. Local control can be achieved with wide excision and reconstruction.

Emergency Radiology "Boot Camp": Educating Emergency Medicine Residents Using E-learning Radiology Modules.

OBJECTIVES: There is an overall paucity of literature on the radiologic education of emergency medicine (EM) clinicians. Given the fact that many EM clinicians preliminarily review images for their patients, we hypothesized that a brief imaging curriculum could be efficacious in teaching basic and relevant radiologic interpretation. METHODS: We designed a 4-hour "radiology boot camp" for a group of 20 EM residents (from all years of training) covering several subject specific e-learning modules. They completed precourse and postcourse quizzes to evaluate the efficacy of these modules. These modules included interactive PowerPoint-based tutorials, games, and imaging decision support simulators. Matched results from the pre- and posttests were analyzed using paired t test. An additional questionnaire was administered to the EM residents to evaluate their perception of the educational experience. RESULTS: The precourse and postcourse quizzes demonstrated a statistically significant level of improved knowledge due to the educational modules (p < 0.0001). In addition, all of the participants believed the modules were a useful learning experience (100%) and a vast majority described them as a valuable resource for future reference (95%). CONCLUSION: We demonstrate a model for providing an easy and effective means of educating EM residents on basic imaging interpretation and utilization, using e-learning modules.
