Radiology resident proficiency in identifying misplaced lines, tubes, and devices: a simulation-based study using WIDI SIM.

Purpose: Accurate placement of medical devices is crucial in critical care to prevent severe complications. This study aims to evaluate radiology residents' proficiency in identifying four specific critical misplacements of medical devices using the Wisdom in Diagnostic Imaging Simulation (WIDI SIM).

Methods: A retrospective analysis was conducted on 1,102 responses from radiology residents who participated in the WIDI SIM between 2010 and 2022.

Correlation between adult trauma center status and radiology resident performance on trauma cases in the WIDI SIM exam.

Purpose: To assess whether adult trauma center status influences radiology resident performance on trauma cases in the Emergent/Critical Care Imaging SIMulation (WIDI SIM) exam.

Materials And Methods: This retrospective study analyzed 29,290 WIDI SIM exam scores from 110 adult trauma cases across 55 radiology residency programs. Residents were categorized by training level-R1 (n = 17,801), R2 (n = 9,136), R3 (n = 1,826), R4 (n = 527)-and by their program's adult trauma center designation: Level 1 (n = 20,121), Level 2 (n = 1,870), Level 3 (n = 1,029), Level 4 (n = 487), and no trauma designation (n = 5,834).

Radiology resident proficiency in pediatric trauma cases: a comparative analysis based on trauma center status using the WIDI SIM exam.

Purpose: To investigate the correlation between pediatric and adult trauma center status and radiology resident performance on pediatric trauma cases using the WIDI SIM exam.

Materials And Methods: The WIDI SIM is a validated computer-aided simulation that assesses radiology residents' preparedness for independent call duty. It includes 65 cases across various imaging modalities derived from actual patient encounters.

Challenges in diagnosis of calcaneal fractures: an examination using the WIDI SIM platform.

Introduction: The calcaneus is the most commonly fractured tarsal bone. Diagnosis is often challenging due to subtle radiographic changes and requires timely identification to prevent complications, including subtalar arthritis, neurovascular injury, malunion, osteomyelitis, and compartment syndrome. Treatment varies based on fracture type, with non-surgical methods for non-displaced stress fractures and surgical interventions for displaced or intra-articular fractures.

An assessment of radiology resident competency in identifying suppurative retropharyngeal lymphadenitis: an examination using the WIDI SIM platform.

Background And Purpose: Suppurative retropharyngeal lymphadenitis is a retropharyngeal space infection almost exclusively seen in the young (4-8 years old) pediatric population. It can be misdiagnosed as a retropharyngeal abscess, leading to unnecessary invasive treatment procedures. This retrospective study aims to assess radiology residents' ability to independently identify CT imaging findings and make a definitive diagnosis of suppurative retropharyngeal lymphadenitis in a simulated call environment.

Radiology resident competency in detecting basilar artery occlusion: a simulation-based assessment.

Purpose: Basilar artery strokes are rare but can have characteristic imaging findings that can often be overlooked. This retrospective study aims to assess radiology residents' ability to identify CT imaging findings of basilar artery occlusion in a simulated call environment.

Methods: The Wisdom in Diagnostic Imaging Emergent/Critical Care Radiology Simulation (WIDI SIM)-a tested and reliable computer-aided emergency imaging simulation-was employed to assess resident readiness for independent radiology call.

Enhancing Radiology Education With a Case-Based Intro to Radiology on the UF WIDI e-Learning Platform.

Rationale And Objectives: This study explores the implementation and efficacy of an online, interactive, case-based radiology education tool, Wisdom in Diagnostic Imaging (WIDI) Case-Based Intro to Radiology (CBIR). We hypothesize that the WIDI CBIR platform would enhance radiology teaching, foster critical thinking, and provide a comprehensive curriculum in imaging interpretation and utilization.

Materials And Methods: A focus group consisting of 1 undergraduate, 7 medical students, 9 physician assistant students, and 3 PhD students participated in this study.

Bubbles in the belly: How well do radiology trainees recognize pneumatosis in pediatric patients on plain film?

Objectives: Pneumatosis intestinalis is a radiographic finding that refers to the presence of gas within the walls of the small or large bowel. This sign is diagnostic in the setting of premature infants with suspected necrotizing enterocolitis. Earlier detection of NEC on X-ray is vital to improve the overall management in these infants.

Rate of resident recognition of nonaccidental trauma: how well do residents perform?

Background: A resident working under the entrustable professional activity of a graduated independent coverage model must identify nonaccidental trauma and notify clinicians of this concern to facilitate potential removal of the child from harm. The resident's role in identifying child abuse has not previously been studied.

Objective: The purpose of this study was to assess radiology residents' ability to identify radiographic imaging findings of nonaccidental trauma in a simulated call environment.

Full Resolution Simulation for Evaluation of Critical Care Imaging Interpretation; Part 2: Random Effects Reveal the Interplay Between Case Difficulty, Resident Competence, and the Training Environment.

Rationale And Objectives: To further characterize empirical data from a full-resolution simulation of critical care imaging coupled with post hoc grading of resident's interpretations by senior radiologists. To present results from estimating the random effects terms in a comprehensive mixed (hierarchical) regression model.

Materials And Methods: After accounting for 9 fixed effects detailed in Part 1 of this paper, we estimated normally distributed random effects, expressed in terms of score offsets for each case, resident, program, and grader.

Full Resolution Simulation for Evaluation of Critical Care Imaging Interpretation; Part 1: Fixed Effects Identify Influences of Exam, Specialty, Fatigue, and Training on Resident Performance.

Rationale And Objectives: To describe our full-resolution simulation of critical care imaging coupled with posthoc grading of resident's interpretations and present results from the fixed effects terms in a comprehensive mixed regression model of the resulting scores.

Materials And Methods: The system delivered full resolution DICOM studies via clinical-grade viewing software integrated with a custom built web-based workflow and reporting system. The interpretations submitted by participating residents from 47 different programs were graded (scores of 0-10) on a case by case basis by a cadre of faculty members from our department.

Bad for Breathing: A Pictorial of Drug-Induced Pulmonary Disease.

Drug-induced lung disease has been described with over 300 different agents, some of which are asymptomatic and may first present on imaging. These pulmonary diseases may present with variable imaging manifestations, and often overlap with other etiologies such as rejection, lymphoproliferative disorders, and infection that may be suspected in this patient population. However, there are several drugs that have classic imaging appearances, and in the proper clinical context, the radiologist should include their toxicity in the differential diagnosis, potentially expediting withdrawal of the drug and avoiding irreversible lung injury such as fibrosis.
