Purpose: To analyse technical and clinical success of transjugular intrahepatic portosystemic shunt (TIPS) in patients with portal hypertension and compare a stent and a stentgraft with regard to clinical and technical outcome and associated costs.
Purpose: To evaluate the feasibility, risks, and techniques of percutaneous removal of permanent TrapEase and Simon Nitinol IVC filters.
Purpose: The aim of this study was to investigate the effect of stent cell geometry on midterm results of carotid artery stenting (CAS).
Interventional radiology (IR) plays a vital role in modern medicine, with increasing demand for services, but with a shortage of experienced interventionalists. The aim of this study was to determine the impact of a recently introduced IR curriculum on perception, knowledge, and interest of medical students regarding various aspects of IR.
Purpose: To assess the relationship between the systolic sac pressure index (SPI) and the presence of endoleaks 12 months after endovascular abdominal aortic aneurysm repair (EVAR).
Background: This study was designed to evaluate the utility of dual phase cone beam computed tomography (DP-CBCT) and automatic vessel detection (AVD) software to guide transarterial embolization (TAE) of angiographically challenging arterial bleedings in emergency settings.
Purpose: The purpose of this technical note is to demonstrate the novel use of CT-guided superior vena cava (SVC) puncture and subsequent tunnelled haemodialysis (HD) line placement in end-stage renal failure (ESRF) patients with central venous obstruction refractory to conventional percutaneous venoplasty (PTV) and wire transgression, thereby allowing resumption of HD.
Purpose: Catheter-directed computed tomography angiography (CCTA) has been shown to reduce the contrast volumes required in conventional CTA, thus minimizing the risk of contrast-induced nephropathy (CIN).
Objective: To compare temperature, energy, and coagulation between hydrochloric acid-infused radiofrequency ablation (HAIRFA) and normal saline-infused radiofrequency ablation (NSIRFA) in ex vivo porcine liver model.
Purpose: To perform a systematic review and meta-analysis of the diagnostic performance of computed tomography (CT) and magnetic resonance (MR) imaging as noninvasive modalities for evaluating hepatocellular carcinoma (HCC) in patients with chronic liver disease.
Purpose: To assess the accuracy of computed tomographic (CT) examinations performed for the purpose of transcatheter aortic valve replacement (TAVR) planning to diagnose obstructive coronary artery disease (CAD).
OBJECTIVE. Transjugular intrahepatic portosystemic shunt (TIPS) creation increases the risk of hepatic encephalopathy due to overshunting. Techniques exist to secondarily reduce the shunt for refractory encephalopathy. The purpose of this article is to describe a technique for primary TIPS restriction using a balloon-expandable stent within the transvenous hepatic track followed by deployment of a self-expanding polytetrafluoroethylene–lined stent-graft within the balloon-expandable stent to create the TIPS.
OBJECTIVE. Magnification is a well-known, but often overlooked, factor impacting radiation exposure. Modern angiography units are commonly offered with single large monitors that allow multiple configurations, including wide display setting in addition to standard display setting similar to a classic arrangement of multiple monitors.
OBJECTIVE. Cosmetic plastic surgery procedures, as well as implants, are increasingly being performed. These implants are often encountered on routine imaging examinations, and radiologists are often asked to evaluate for complications or evidence of failure. Pectoral augmentation, gluteal augmentation, body lift and abdominoplasty, and penile and testicular prostheses are reviewed in this article.
OBJECTIVE. The purpose of this study was to evaluate the effectiveness of retroperitoneal organ displacement for image-guided percutaneous biopsy.
