Gastrointestinal stromal tumor (GIST) frequently metastasizes to the liver, and conventional staging computed tomography (CT) protocols use multiphasic contrast enhancement for detection of hepatic lesions. We evaluated the sensitivity of arterial phase CT imaging for hepatic GIST metastases compared with that of standard (portal venous [PV]) phase imaging. We conducted a retrospective review of patients who presented with hepatic GIST metastases identified on staging CT examinations between 2005 and 2015.

This study assessed the poverty-related attitudes of pre-clinical medical students (first and second years) versus clinical medical students (third and fourth years). First through fourth year medical students voluntarily completed the Attitude Towards Poverty scale. First and second year students were classified together in the preclinical group and third and fourth year students together in the clinical group.

Methods: An IRB-approved retrospective study at our academic institution was conducted on all patients treated by BAE for hemoptysis from lung malignancy. Outcome and safety measures were documented according to Society of Interventional Radiology (SIR) practice guidelines.
Purpose: The aim of the study was to compare the rate of pneumothorax and chest tube placement in patients undergoing conventional lung biopsy with those undergoing core lung biopsy for biomarker analysis.
Materials And Methods: Twenty-three patients had biopsies performed for biomarker analysis (5 male, 18 female patients, mean age 67 y), and 173 patients underwent standard diagnostic lung biopsy (86 male, 87 female patients, mean age 68 y). All biopsies were performed under computed tomography guidance using the coaxial technique (19 G introducer needle and 20 G core biopsy needle).
Purpose: To assess long-term outcomes including risk of complications and nutritional benefits of mushroom-retained (pull-type) gastrostomy catheters placed in patients by interventional radiologists.
Materials And Methods: All patients who received pull-type gastrostomy tubes between 2010 and 2013 were retrospectively reviewed, including 142 men (average weight, 169.6 lb [76.
Purpose: The purpose of this study was to investigate the impact of lesion proximity to the diaphragm on computed tomography (CT)-guided percutaneous biopsy yield and pneumothorax rates.
Materials And Methods: An Institutional Review Board-approved retrospective review of all CT-guided percutaneous core lung biopsies at a single institution performed between August 1, 2011 and July 31, 2013 yielded 168 patients who underwent a total of 174 lung biopsies. The shortest distance of the target lesion from the diaphragm was measured on preprocedure sagittal reformatted CT images.
Purpose: To investigate the value of collateral vein embolization (CVE) as a salvage treatment for nonmaturing native arteriovenous fistulae (AVFs) in patients requiring hemodialysis.
Materials And Methods: A total of 49 patients undergoing CVE (N = 65) for immature native AVFs at a single institution were reviewed. The study included 42 patients treated by 56 embolizations.

Purpose: The aim of this study was to investigate dual-lumen chest port infection rates in patients with head and neck cancer (HNC) compared to those with other malignancies (non-HNC).
Materials And Methods: An IRB-approved retrospective study was performed on 1,094 consecutive chest ports placed over a 2-year period. Patients with poor follow-up (n = 53), no oncologic history (n = 13), or single-lumen ports (n = 183) were excluded yielding a study population of 845 patients.
Purpose: To retrospectively compare the incidences of complications with barbed suture versus conventional interrupted suture for incision closure in implantable chest ports.
Materials And Methods: A total of 715 power-injectable dual-lumen chest ports placed between 2011 and 2013 were studied. Primary outcomes included wound dehiscence, local port infection, local infections treated by wound packing, early infections within 30 days, and total infections.
