PURPOSE: To determine the effects of sublingual glyceryl trinitrate (GTN) on the quality of planning computed tomography (CT) angiography performed prior to prostate artery embolization (PAE). MATERIALS AND METHODS: A retrospective cohort study was performed on patients who had previously undergone CT angiography before a procedure for PAE at our institution. Early CT angiography studies for PAE at our single center had initially been performed without GTN. These were compared to subsequent CT angiography studies that had been performed with GTN, after a previously implemented change in practice...

PURPOSE: To examine differences in outcome and response of cirrhotomimetic (CMM) hepatocellular carcinoma (HCC) to a combination of bridging transcatheter arterial chemoembolization and orthotopic liver transplantation (OLT) compared with non-CMM HCC. MATERIALS AND METHODS: All patients with pathologically proven CMM HCC who underwent bridging transcatheter arterial chemoembolization before OLT between 2007 and 2013 (n = 23) were retrospectively compared with a control group of patients with pathologically proven non-CMM HCC (n = 46)...

PURPOSE: To analyze technique, outcomes, and complications of a large series of pediatric percutaneous nephrostomy (PCN) procedures performed at 4 tertiary pediatric centers. MATERIALS AND METHODS: Retrospective multicenter study of PCNs performed during an 11-year period. Six hundred seventy-five PCNs were performed on 441 patients (median age: 4 y, range: 1 d-18 y, median weight: 17 kg, range: 0.7-112 kg); 31% were younger than 1 year. The most frequent indications for PCN procedures included hydronephrosis (57%), calculus (14%), and infection (12%)...

PURPOSE: To evaluate accuracy of virtual parenchymal perfusion (VPP) algorithm developed for targeting liver cancer during intra-arterial therapy (IAT) using cone-beam CT guidance. MATERIALS AND METHODS: VPP was retrospectively applied to 15 patients who underwent IAT for liver cancer. Virtual territory (VT) was estimated after positioning a virtual injection point on nonselective dual-phase (DP) cone-beam CT images acquired during hepatic arteriography at the same position chosen for selective treatment...

PURPOSE: To determine whether transradial access (TRA) or transfemoral access (TFA) provides better patient satisfaction during intra-arterial therapy (IAT) for liver cancer. MATERIALS AND METHODS: This randomized, prospective, intra- and interpatient controlled trial compared TRA vs TFA accesses in patients with primary or metastatic liver cancer undergoing IAT. After having one of each type of access (1 TRA and 1 TFA), all patients selected their preferred access regardless of whether a third intervention was indicated...
