RATIONALE AND OBJECTIVES: Participation in clinical research can be both highly rewarding and logistically demanding. As highlighted by recent Food and Drug Administration guidance, imaging has become an integral part of this research. The unique technical and administrative aspects of clinical trial imaging may differ substantially from those of standard-of-care imaging and thus burden the established clinical infrastructure at investigational sites. Failure to comply with requirements can lead to unusable data, repeat imaging, or the removal of patients from the trial...

PURPOSE: To compare the traditional lecture to a hybrid interactive and didactic teaching format with regards to radiology resident short- and long-term retention, as well as attention. MATERIALS AND METHODS: The tested hybrid format consists of a 30-minute didactic lecture followed by 30 minutes of interactive cases based on material from the lecture portion. Faculty members were randomly selected to give a 60-minute lecture or a hybrid presentation. To assess short- and long-term retention, a test developed from the presenter's slides was sent to all residents approximately 15 minutes after each presentation, and again approximately 3 months later...

RATIONALE AND OBJECTIVES: The goal of this retrospective study was to evaluate the rate of immediate post-biopsy clip migration on an upright digital tomosynthesis-guided vacuum-assisted core biopsy unit and determine if any factors were associated with immediate clip migration. MATERIALS AND METHODS: We performed a retrospective review of patients who had undergone a biopsy performed at one facility from November 1, 2014 to September 30, 2016. Post-biopsy mammograms were reviewed to assess immediate clip position relative to the targeted lesion...

RATIONALE AND OBJECTIVES: To examine the ability of a pseudoreader study design to estimate the observer performance obtained using a traditional fully crossed, multireader, multicase (MRMC) study. MATERIALS AND METHODS: A 10-reader MRMC study with 20 computed tomography datasets was designed to measure observer performance on four novel noise reduction methods. This study served as the foundation for the empirical evaluation of three different pseudoreader designs, each of which used a similar bootstrap approach for generating 2000 realizations from the fully crossed study...

RATIONALE AND OBJECTIVES: Lymphangiomatosis is a rare disease characterized by the widespread presence of lymphangiomas in any part of the body. In previous studies, lymphatic vessel abnormalities in lymphangiomatosis have only rarely been mentioned. The objective of this paper is to discuss the imaging features of lymphangiomatosis, including cystic lesions and lymphatic abnormalities, on computed tomography lymphangiography (CTL). MATERIALS AND METHODS: All 34 patients who were diagnosed with lymphangiomatosis underwent direct lymphangiography followed by CTL...

RATIONALE AND OBJECTIVES: We sought to compare the prevalence and volume of lipid plaque, fibrous plaque, and calcified plaque in patients with smokers versus nonsmokers. MATERIALS AND METHODS: We studied consecutive patients suspected of coronary artery disease and who underwent coronary computed tomography angiography. A structured interview and review of existing clinical data was conducted before computed tomography angiography to collect information on demographic characteristics, the presence of cardiovascular risk factors...

Given the rapid pace at which modern radiology is evolving and the associated paradigm shifts in health care delivery, it is critical that radiologists adapt and constantly update the skills and knowledge required to practice safe, patient-centered care. The Association of University Radiologists-Radiology Research Alliance Lifelong Learning Task Force convened to explore the current status and future directions of lifelong learning in radiology and summarized its finding in this article. We review the various learning platforms and resources available to radiologists in their self-motivated and self-directed pursuit of lifelong learning...

BACKGROUND: Mammography (MMG) is widely used for the screening and diagnosis of breast cancer. High breast density on MMG prevents breast cancer detection. In the present study, we analyzed the effects of parity and infant feeding method on mammographic breast density. MATERIALS AND METHODS: Ninety women diagnosed as having breast cancer were analyzed. Using the results of medical questionnaires, subjects were grouped according to their parity and infant feeding method, into either nulliparity or parity, and formula-feeding or breastfeeding...

RATIONALE AND OBJECTIVES: To compare the cost of ultrasound (US) versus magnetic resonance imaging (MRI) using time-driven activity-based costing in adolescent female patients with suspected appendicitis. MATERIALS AND METHODS: Process maps were created using data from electronic medical record review and patient shadowing for adolescent female patients undergoing US or noncontrast MRI exams of the abdomen and pelvis for suspected appendicitis. Capacity cost rates for all personnel, equipment, facilities, and supplies in each exam pathway were established from institutional accounting data...

As the movement for increased transparency in healthcare continues, more and more patients are accessing their imaging reports via patient portals. The shift to structured radiology reports has increased report clarity for referring providers and is supported by most radiologists. When radiologists address the clinical question that was posed, avoid the use of abbreviations, and create a report impression that is as simple as possible, we provide real added value via effective communication through our reports...

RATIONALE AND OBJECTIVES: Intravenous thrombolysis decision-making and obtaining of consent would be assisted by an individualized risk-benefit ratio. Deep learning (DL) models may be able to assist with this patient selection. MATERIALS AND METHODS: Clinical data regarding consecutive patients who received intravenous thrombolysis across two tertiary hospitals over a 7-year period were extracted from existing databases. The noncontrast computed tomography brain scans for these patients were then retrieved with hospital picture archiving and communication systems...
