BACKGROUND: The rate of vena cava (IVC) filter placement has increased over the past decade, especially in the orthopaedic trauma patient population. With the increasing use of IVC filters, radiologists and referring clinicians must be familiar with potential complications. CLINICAL CASE: This case report presents an 18-year-old polytraumatized patient who had an IVC filter placed and required T8-L2 posterior spinal fusion. At 4.5 years of follow-up, a computed tomography (CT) scan for painful spinal hardware incidentally found that the IVC filter had migrated into the L3 vertebral body...

PURPOSE: This resident-driven quality improvement project was undertaken to assess the effectiveness of structured reporting to reduce revision rates for afterhours reports dictated by residents. METHODS: The first part of the study assessed baseline revision rates for head and neck CT angiography (CTA) examinations dictated by residents during afterhours call. A structured report was subsequently created based on templates on the RSNA informatics reporting website and critical findings that should be assessed for on all CTA examinations...

Enchondromas are among the most common benign tumors seen in the skeleton. They are encountered frequently in routine clinical practice. The purpose of this review is to help radiologists confidently diagnose enchondroma and distinguish it from other entities, such as bone infarct, bone graft, and low-grade chondrosarcoma.

PURPOSE: To compare the value of dynamic contrast-enhanced magnetic resonance imaging-pharmacokinetic (PK) parameters vs tumor volume in predicting breast cancer neoadjuvant chemotherapy response (NACR) and patient survival. SUBJECTS AND METHODS: Sixty-six patients with locally advanced breast cancer who underwent breast MRI monitoring of NACR were retrospectively analyzed. We compared baseline transfer constant (Ktrans ), reflux rate contrast (kep ), and extracellular extravascular volume fraction (ve ) with the same parameters obtained at early postchemotherapy MRI, and examined model-independent changes in time-intensity curves (maximum slope, contrast enhancement ratio, and IAUC90)...

Angiomyolipomas (AML) are benign tumors of the kidneys frequently encountered in radiologic practice in large tertiary centers. In comparison to renal cell carcinomas (RCC), AML are seldom treated unless they are large, undergo malignant transformation or develop complications like acute hemorrhage. The common garden triphasic (classic) AML is an easy diagnosis, however, some variants lack macroscopic fat in which case the radiologic differentiation from RCC becomes challenging. Several imaging features, both qualitative and quantitative, have been described in differentiating the 2 entities...

BACKGROUND: Bibliometric analyses by highest number of citations can help researchers and funding agencies in determining the most influential articles in a field. The main objective of this analysis was to identify the top 100 cited articles addressing radiation exposure from medical imaging and assess their characteristics. METHODS: Relevant articles were extracted from the Scopus database after a systematic search by researchers using an iteratively defined Boolean search string...

PURPOSE: Interventional radiology-operated endoscopy is an underused technique, which may have a significant impact on the ability to treat patients with a variety of conditions. The purpose of this article is to discuss the setup, equipment, and potential clinical uses of interventional radiology-operated endoscopy. METHODS: A number of new and innovative interventions may be performed in the biliary, genitourinary, and gastrointestinal systems through percutaneous access that interventional radiologists already create...

Congenital intrahepatic portosystemic venous shunts (CIPVS) are rare anomalies that can be detected before birth or in early infancy or later in life. Symptomatic shunts are treated as they carry high risk of complications like hepatic encephalopathy. Various treatment options include surgery, endovascular embolization, and percutaneous closure devices. We treated 2 infants with CIPVS successfully by endovascular embolization of the shunt using vascular plug through transjugular route. Transabdominal ultrasound guidance in addition to fluoroscopy was used at the time of vascular plug placement...

PURPOSE: Identify when current radiology residents initially became interested in radiology, which factors influenced their decision to pursue a career in radiology, and which factors correlate with job satisfaction. METHODS: An online survey was distributed to United States radiology residents between December 7, 2016 and March 31, 2017. Respondents identified the most appealing aspects of radiology during medical school, identified experiences most influential in choosing radiology, and scored job satisfaction on visual analog scales...

PURPOSE: ACR workforce surveys have suggested progressive recovery in the number of available jobs for radiologists over the past several years. The purpose of this study was to ascertain the status of jobs available in diagnostic radiology as well as to analyze the content of the job boards of general radiology and subspecialty societies with the intent of uncovering differences in posting preferences to better steer job seekers. METHODS: The content of the online job boards hosted by the SPR, ASNR, ACR, and RSNA was evaluated on 365 consecutive days between July 1, 2016 and June 30, 2016...

OBJECTIVE: Increased attention to quality and safety has led to a re-evaluation of the classic apprenticeship model for procedural training. Many have proposed simulation as a supplementary teaching tool. The purpose of this study was to assess radiology resident exposure to procedural training and procedural simulation. MATERIALS AND METHODS: An IRB-exempt online survey was distributed to current radiology residents in the United States by e-mail. Survey results were summarized using frequency and percentages...

Stephen R. Covey's landmark work in the field of effectiveness and professional development delineated first 7, then ultimately eight, habits of highly effective people with applicability to all professions.1 This article describes the eight habits in specific relation to the radiologist, and proposes a ninth habit to help one bring a positive and centered approach during the journey to effectiveness and beyond.

PURPOSE: To determine distances between patient centroid and gantry isocenter during CT imaging of the chest, abdomen, and/or pelvis, and to evaluate differences based on patient gender, scan region, patient position, and gantry aperture. MATERIALS AND METHODS: A water phantom and an anthropomorphic phantom were imaged in the centered position in the CT gantry and at several off-centered positions. Additionally, data from 57,621 adult chest, abdomen, and/or pelvic CT acquisitions were evaluated...

PURPOSE: The goal of our study was to compile a list of the top 100 most-cited articles in stroke imaging literature across all peer-reviewed scientific journals. These articles were then analyzed to identify current trends in stroke imaging research and determine the characteristics of highly-cited articles. MATERIALS AND METHODS: A database of the top 100 most-cited articles was created using Scopus and Web of Science. Articles were reviewed for applicability by 2 fellowship-trained radiologists with over 10 years of combined experience in neuroimaging...

The aim of this work is to review the spectrum of sinonasal lesions that extend to the endocranium and to present key points that may narrow the differential diagnosis. The most frequent sinonasal lesions that extend into the endocranium are malignant; however, benign entities are not unusual. Imaging diagnosis is difficult because malignant lesions and benign entities share similar clinical, epidemiologic, and imaging features. Tumor features in relation to bone, intratumor homogeneity and structure, magnetic resonance imaging signal, along with clinical and epidemiologic aspects may allow an appropriate diagnostic focus with important management implications...
