RATIONALE AND OBJECTIVES: To determine the metabolic effects of developmental venous anomalies (DVAs) and to correlate those effects with conventional magnetic resonance imaging (MRI) findings. MATERIALS AND METHODS: We conducted a retrospective review of MRI and brain 18F-fluorodeoxyglucose positron emission tomography (18 F-FDG-PET) examinations in subjects with DVAs. Conventional MRI was used to determine DVA number, location, size, and associated parenchymal findings such as atrophy, hemorrhage, cavernoma, capillary telangiectasia, cortical dysplasia/polymicrogyria, and white matter signal abnormality...

RATIONALE AND OBJECTIVES: The Electronic Resident Application Service (ERAS) publishes monthly statistics before the match and the National Resident Matching Program publishes the match outcomes. We sought to determine whether early ERAS data influences applicant behavior and correlates with match outcomes. MATERIALS AND METHODS: We searched the 2007-2017 ERAS archives for the applicant pool size (PS), the average number of applications per program (AP), and the average number of applications per applicant (AA) in November, before radiology match, and the 2007-2017 National Resident Matching Program archives for the average number of ranked applicants needed to fill each position (ANRA) and the number of unfilled positions (UP) in radiology match...

RATIONALE AND OBJECTIVES: In hepatocellular carcinoma (HCC), the tumor protein 53 (TP53) gene is frequently mutated and the mutations have been associated with poor prognosis. We aim to retrospectively identify the relationship between TP53 mutation status, tumor size (long-axis diameter, short-axis diameter, and long-to-short-axis ratio [L/S ratio]), margin and multifocality in surgically resected HCC. MATERIALS AND METHODS: The image features and TP53 mutation data from 78 patients generated with National Cancer Institute's multi-institutional The Cancer Genome Atlas (TCGA)/The Cancer Imaging Archive databases were assessed...

PURPOSE: Response Evaluation Criteria in Solid Tumors (RECIST 1.1) is the gold standard for imaging response evaluation in cancer trials. We sought to evaluate consistency of applying RECIST 1.1 between 2 conventionally trained radiologists, designated as A and B; identify reasons for variation; and reconcile these differences for future studies. METHODS: The study was approved as an institutional quality check exercise. Since no identifiable patient data was collected or used, a waiver of informed consent was granted...

RATIONALE AND OBJECTIVES: Transjugular intrahepatic portosystemic shunt (TIPS) placement using the same-diameter covered stents can lead to differed declines of portal venous pressure declines (PVDs). This study aimed to compare the long-term shunt patency and clinical efficacy of TIPS placement that caused low PVDs (≤9 mmHg) and high PVDs (>9 mmHg). MATERIALS AND METHODS: A total of 129 patients treated by TIPS placement with 8 mm-diameter polytetrafluoroethylene covered stents were included and analyzed retrospectively...

RATIONALE AND OBJECTIVES: This study aims to quantitatively compare T2* measurements of the talar cartilage between chronic lateral ankle instability (LAI) patients with lateral ligament injury and healthy volunteers, and to assess the association of T2* value with American Orthopedic Foot and Ankle Society (AOFAS) score. MATERIALS AND METHODS: Nineteen consecutive patients with chronic LAI (LAI group) and 19 healthy individuals (control group) were enrolled. Biochemical magnetic resonance examination of the ankle was performed in all participants using three-dimensional gradient-echo T2* mapping...

PURPOSE: To determine the yield of routine image-guided core biopsy of renal cell carcinoma (RCC) thermal ablation zones. METHODS: Institutional review board approval was obtained for this Health Insurance Portability and Accountability Act-compliant quality improvement effort. Routine core biopsy of RCC ablation zones was performed 2 months postablation from July 2003 to December 2014. Routine nicotinamide adenine dinucleotide staining was performed by specialized genitourinary pathologists to assess cell viability...

RATIONALE AND OBJECTIVES: The aim of this study was to prospectively examine the impact of a tablet-based curriculum on the radiology resident educational experience. MATERIALS AND METHODS: A comprehensive tablet-based curriculum was developed by creating subspecialty modules with appropriate content level for each required rotation at our diagnostic radiology residency program. Daily assignments included key learning points, readings, and reference presentation slides, covering all objectives published by the ABR Core Exam Study Guide...

RATIONALE AND OBJECTIVES: To assess the implementation of radiation dose monitoring software, create a process for clinical follow-up and documentation of high-dose cases, and quantify the number of patient reported radiation-induced tissue reactions in fluoroscopically guided interventional radiology (IR) and neuro-interventional radiology (NIR) procedures. MATERIALS AND METHODS: Web-based radiation dose monitoring software was installed at our institution and a process to flag all procedures with reference point air kerma (Ka,r ) > 5000 mGy was implemented...

RATIONALE AND OBJECTIVES: Efficiency is central to current radiology practice. Knowledge of report generation timing is essential for workload optimization and departmental staffing decisions. Yet little research evaluates the distribution of activities performed by neuroradiologists in daily work. MATERIALS AND METHODS: This observational study tracked radiologists interpreting 358 brain magnetic resonance imaging (MRI) in an academic practice over 9 months. We measured the total duration from study opening to report signing and times for five activities performed during this period: image viewing, report transcription, obtaining clinical data, education, and other...
