Purpose: To determine the size of pulmonary artery (PA) at risk for occlusion during percutaneous microwave ablation and to assess the effect of vessel diameter, number, and patency, on ablation zone volume.
Background: Radioembolization (RE) with 90yttrium (90Y) resin microspheres generally employs a sandwich technique with separate sequential administration of contrast medium (CM), followed by vehicle (e.g., glucose 5% [G5] solution), then 90Y resin microspheres (in G5), then G5, and then CM again to avoid contact of CM and microspheres under fluoroscopic guidance. This study evaluates the visualization quality and safety of a modified sandwich technique with a 50/50-mixture of CM (Imeron 300) and G5 for administration of 90Y resin microspheres.
OBJECTIVE. The purpose of this study is to assess the utility of a volume navigation technique (VNT) for ultrasound-guided biopsy of MRI-detected, but sonographically ambiguous or occult, breast lesions.
OBJECTIVE. The purposes of this article are to describe the indications, techniques, and results of arterially directed therapies and ablation and to review the imaging assessment of response and complications.
OBJECTIVE. The purpose of this study was to identify the details of percutaneous catheter drainage (PCD) of pyogenic liver abscesses, the etiologic factors, and the management techniques that contribute to successful treatment.
OBJECTIVE. The purpose of this study is to evaluate the histopathologic diagnostic yield, sample size, procedural time, and dose-length product (DLP) for the biopsy of CT-occult lesions found at MRI or PET or both.
OBJECTIVE. The purpose of this study was to investigate the effect of a biopsy center—a dedicated space with a dedicated ultrasound machine and technologist, staffed daily by a radiologist responsible for performing ultrasound-guided procedures only—on the rate of non-diagnostic or unsatisfactory thyroid fine-needle aspiration (FNA).
OBJECTIVE. The purpose of this study is to determine the efficacy and tolerability of transarterial chemoembolization (TACE) using polyethylene glycol (PEG) drug-elutable microspheres loaded with doxorubicin for treatment of hepatocellular carcinoma (HCC).
OBJECTIVE. The purpose of this article is to describe a handheld external compression device used to facilitate CT fluoroscopy–guided percutaneous interventions in the abdomen.
OBJECTIVE. The purpose of this study was to evaluate predictors of reduction in ammonia levels by occlusion of portosystemic shunts (PSS) in patients with cirrhosis.
OBJECTIVE. The purpose of this study was to compare the outcomes of second uterine artery embolization (UAE) with those of first UAE for symptomatic uterine leiomyoma.
Purpose: To evaluate the effects of tumor complexity and technique on early and midterm oncologic efficacy and rate of complications for 100 consecutive biopsy-proved stage T1a renal cell carcinomas (RCCs) treated with percutaneous microwave ablation.
In patients with cirrhosis with refractory ascites, the 10-mm-diameter polytetrafluoroethylene-covered transjugular intrahepatic portosystemic shunt, compared with the 8-mm stent, was associated with a greater reduction in portosystemic gradient and lower need for paracentesis; the 10-mm stent was not associated with higher incidence and severity of hepatic encephalopathy or other unfavorable outcomes, including procedural-related mortality.
Volumetric enhancing tumor burden is an early treatment response biomarker and surrogate for survival in patients with multifocal, bilobar neuroendocrine liver metastases after the first transarterial chemoembolization.
Purpose: To compare segmental radioembolization with segmental chemoembolization for localized, unresectable hepatocellular carcinoma (HCC) not amenable to ablation.
