RATIONALE AND OBJECTIVES: Diagnostic radiology resident assessment has evolved from a traditional oral examination to computerized testing. Teaching faculty struggle to reconcile the differences between traditional teaching methods and residents' new preferences for computerized testing models generated by new examination styles. We aim to summarize the collective experiences of senior residents at three different teaching hospitals who participated in case review sessions using a computer-based, interactive, anonymous teaching tool, rather than the Socratic method...

RATIONALE AND OBJECTIVES: Abdominal magnetic resonance angiography (MRA) has gained favor in pediatric patients owing to its lack of ionizing radiation and noninvasive nature. Reports exist regarding incidental findings on body MRA in adult patients. However, the incidental findings in pediatric abdominal MRA have not been previously reported. Our study aims to determine the frequencies, characteristics, and categories of incidental findings in pediatric patients undergoing abdominal MRA...

RATIONALE AND OBJECTIVES: The purpose of this study was to critically appraise and compare the diagnostic performance of imaging modalities that are used for the diagnosis of intussusception and methods used in the treatment of ileocolic intussusception. METHODS: A focused clinical question was constructed and the literature was searched using the patient, intervention, comparison, outcome (PICO) method comparing radiography, ultrasound, and computed tomography in the detection of intussusception...

RATIONALE AND OBJECTIVES: Pulmonary embolism (PE) is a common condition associated with significant morbidity and mortality. Diagnostic test characteristics reported in terms of sensitivity and specificity are difficult to translate at the clinical level. More relevant measures are likelihood ratios (LRs), which can convert a pretest into a posttest probability. The aim of our study was to calculate the LRs and posttest probabilities for multiple-level test result for ventilation/perfusion (V/Q) lung scintigraphy and for perfusion scintigraphy combined with chest radiography using modified Prospective Investigation of Pulmonary Embolism Diagnosis (PIOPED) II and the Prospective Investigative Study of Pulmonary Embolism Diagnosis (PISAPED) criteria for each clinical probability level for the most commonly used clinical prediction rules (CPR) using the PIOPED data...

As ACGME (Accreditation Council for Graduate Medical Education) requirements have expanded and become increasingly more complex, so has the role of the program coordinator. Over the last decade, the knowledge and skills required to capably administer residency and fellowship training programs have increased in both volume and complexity. Today's coordinators are responsible for more than clerical tasks. They also function as managers and have greater roles in the development and implementation of program initiatives, policies, and outcomes...

RATIONALE AND OBJECTIVES: This study aims to estimate observer performance for a range of dose levels for common computed tomography (CT) examinations (detection of liver metastases or pulmonary nodules, and cause of neurologic deficit) to prioritize noninferior dose levels for further analysis. MATERIALS AND METHODS: Using CT data from 131 examinations (abdominal CT, 44; chest CT, 44; head CT, 43), CT images corresponding to 4%-100% of the routine clinical dose were reconstructed with filtered back projection or iterative reconstruction...

RATIONALE AND OBJECTIVES: The American Board of Radiology Core Examination integrates assessment of physics knowledge into its overall testing of clinical radiology, with an emphasis on understanding image quality and artifacts, radiation dose, and patient safety for each modality or subspecialty organ system. Accordingly, achieving a holistic approach to physics education of radiology residents is a huge challenge. The traditional teaching of radiological physics-simply through didactic lectures-was not designed for such a holistic approach...

RATIONALE AND OBJECTIVE: This study aimed to evaluate the use of an adenosine triphosphate (ATP) monitoring system to minimize surface contamination on inpatient computed tomography (CT) scanners. METHODS: The bore, table, and wrap of two quaternary care inpatient CT scanners (load/scanner: ~ 30-40 CT examinations/day) were assayed with bacterial cultures and an ATP detection system during six prospective iterative plan-do-check-act improvement cycles from January 6, 2016 to October 12, 2016...

RATIONALE AND OBJECTIVES: Infectious encephalitis is a relatively common cause of morbidity and mortality. Treatment of infectious encephalitis with antiviral medication can be highly effective when administered promptly. Clinical mimics of encephalitis arise from a broad range of pathologic processes, including toxic, metabolic, neoplastic, autoimmune, and cardiovascular etiologies. These mimics need to be rapidly differentiated from infectious encephalitis to appropriately manage the correct etiology; however, the many overlapping signs of these various entities present a challenge to accurate diagnosis...

RATIONALE AND OBJECTIVES: This study aims to compare the speed and accuracy of three different software packages in segmenting the liver and the spleen. MATERIALS AND METHODS: The three software packages are Advantage Workstation Solutions (AWS), Claron Technology (Claron) Liver Segmentor, and Vitrea Core Fx (Vitrea).

RATIONALE AND OBJECTIVES: The study aimed to assess the diagnostic benefit of a novel computed tomography (CT) post-processing software generating subtraction maps of longitudinal non-enhanced CT examinations for monitoring the course of myeloma bone disease in the spine. MATERIALS AND METHODS: The local institutional review board approved the retrospective data evaluation. Included were 82 consecutive myeloma patients (46 male; mean age, 65.08 ± 9.76) who underwent 188 repeated whole-body reduced-dose Multislice Detector Computed Tomography (MDCT) at our institution between December 2013 and January 2016...

RATIONALE AND OBJECTIVES: Radiology expertise is dependent on the use of efficient search strategies. The aim of this study is to investigate the effect of teaching search strategies on trainee's accuracy in detecting lung nodules at computed tomography. MATERIALS AND METHODS: Two search strategies, "scanning" and "drilling," were tested with a randomized crossover design. Nineteen junior radiology residents were randomized into two groups. Both groups first completed a baseline lung nodule detection test allowing a free search strategy, followed by a test after scanning instruction and drilling instruction or vice versa...

RATIONALE AND OBJECTIVES: To identify and compare cardiovascular findings on computed tomography (CT) scans after pneumonectomy (PNX) with those after lobectomy (LOBX). MATERIALS AND METHODS: Pre- and postoperative CT scans from 25 PNX patients were retrospectively analyzed and compared to those from 30 LOBX patients. The diameter of the main pulmonary artery (PA) and its ratio to the ascending aorta (PA/Ao) were determined. Cardiac morphometry values were ascertained by measuring maximum diameters of the right and left ventricle on axial (RVaxial, LVaxial) and four-chamber (RV4-ch, LV4-ch) views...

Medical imaging procedures have become a national target in the campaign to reduce wasteful practices. At a minimum, radiology residency programs must integrate high-value curricula and train residents to practice in accordance with value-based principles and new healthcare policy. A greater portion of radiology resident education needs to be devoted to appropriateness education and consultancy training. Ideally, radiology training programs will instill in residents the importance of embracing the movement and leading the change...
