RATIONALE AND OBJECTIVES: The increasing availability of personal health portals has made it easier for patients to obtain their imaging results online. However, the radiology report typically is designed to communicate findings and recommendations to the referring clinician, and may contain many terms unfamiliar to lay readers. We sought to evaluate a web-based interface that presented reports of knee MRI (magnetic resonance imaging) examinations with annotations that included patient-oriented definitions, anatomic illustrations, and hyperlinks to additional information...

Although advanced imaging is an important component of oncology clinical trials, there has not been a lot of success in advancing its use from a research perspective. One likely reason is the lack of consensus on the methodology used to study advanced imaging in trials, which results in a disconcerted research effort and produces data that are difficult to collate for use in validating the imaging components being studied. Imaging is used in cancer clinical trials for various indications, and the study design needed to evaluate the imaging in a particular indication will vary...

RATIONALE AND OBJECTIVE: As health care moves toward bundled payment systems and merit-based incentive models, increasing awareness of the value of the radiologist is essential. A resident-driven clinical imaging rounds (CIR) program initiated at our institution allows radiologists to actively and directly participate in the team-based medical model. A retrospective review of survey data evaluated the qualitative and quantitative effects of CIR on clinical management, communication, and education of referring providers and radiology residents...

RATIONALE AND OBJECTIVES: Emergency department (ED) patients with acute low back pain (LBP) may present with ambiguous clinical findings that pose diagnostic challenges to exclude cauda equina syndrome (CES). As a proof of concept, we aimed to determine the efficacy of a rapid lumbar spine (LS) magnetic resonance imaging (MRI) screening protocol consisting of a single 3D-T2 SPACE FS (3D-T2 Sampling Perfection with Application optimized Contrasts using different flip angle Evolution fat saturated) sequence relative to conventional LS MRI to exclude emergently treatable pathologies in this complex patient population...

RATIONALE AND OBJECTIVES: Diagnostic imaging has many effects and there is no common definition of value in diagnostic radiology. As benefit-risk trade-offs are rarely made explicit, it is not clear which framework is used in clinical guideline development. We describe initial steps toward the creation of a benefit-risk framework for diagnostic radiology. MATERIALS AND METHODS: We performed a literature search and an online survey of physicians to identify and collect benefit-risk criteria (BRC) relevant to diagnostic imaging tests...

RATIONALE AND OBJECTIVES: This study aims to assess the use of skeletal muscle mass measurements at two thoracic levels to diagnose sarcopenia on computed tomography (CT) chest examinations and to analyze the impact of these measurements on clinical outcome parameters following transcatheter aortic valve replacement. MATERIALS AND METHODS: This study retrospectively included 157 patients who underwent preoperative CT examinations. The total muscle area was measured on transverse CT images at the 3rd lumbar and 7th and 12th thoracic levels with skeletal muscle indices (SMIs) calculated at each level...

RATIONALE AND OBJECTIVES: Workplace-based assessments gauge the highest tier of clinical competence. Chart-stimulated recall (CSR) is a workplace-based assessment method that complements chart audit with an interview based on the residents' notes. It allows evaluation of the residents' knowledge and heuristics while providing opportunities for feedback and self-reflection. We evaluated the utility of CSR for improving the radiology residents' reporting skills. MATERIALS AND METHODS: Residents in each year of training were randomly assigned to an intervention group (n = 12) or a control group (n = 13)...

RATIONALE AND OBJECTIVES: The literature surrounding interprofessional education claims that students who learn with, from, and about one another in well-designed interprofessional programs will practice together collaboratively upon graduation, given the skills to do so. The objective of this study was to examine attitudes to interprofessional practice before and after an interprofessional learning (IPL) activity. MATERIALS AND METHODS: A total of 35 postgraduate medical imaging students attended a week-long mammography workshop...

RATIONALE AND OBJECTIVES: To compare adaptive statistical iterative reconstruction (ASIR) and model-based iterative reconstruction (MBIR) algorithms for reduced-dose computed tomography (CT). MATERIALS AND METHODS: Forty-four young oncology patients (mean age 30 ± 9 years) were included. After routine thoraco-abdominal CT (dose 100%, average CTDIvol 9.1 ± 2.4 mGy, range 4.4-16.9 mGy), follow-up CT was acquired at 50% (average CTDIvol 4.5 ± 1.2 mGy, range 2...

RATIONALE AND OBJECTIVES: In clinical guideline or criteria development processes, such as those used in developing American College of Radiology Appropriateness Criteria (ACR AC), experts subjectively evaluate benefits and risks associated with imaging tests and make complex decisions about imaging recommendations. The analytic hierarchy process (AHP) decomposes complex decisions into structured smaller decisions, incorporates quantitative evidence and qualitative expert opinion, and promotes structured consensus building...
