OBJECTIVE. The purpose of this article is to evaluate the efficiency and reproducibility of a contrast-enhanced 3D MR angiography (MRA) protocol, using the provocative arm position on 1.5- and 3-T MRI scanners, and to determine the frequency and distribution of vascular compression and vascular complications in the thoracic outlet.
OBJECTIVE. The objective of our study was to determine whether hysterosalpingography is necessary after Essure microinsert placement by evaluating the rates of appropriate placement and of satisfactory tubal occlusion in a general population.
OBJECTIVE. Response rates to systemic chemotherapy for unresectable pancreatic cancer are low. The purposes of this phases 1 and 2 study of intraarterial therapy were to ascertain the recommended dose of intraarterial chemoinfusion and to evaluate the efficacy and safety of this therapy.
OBJECTIVE. The purpose of this study was to determine whether fusion imaging–guided percutaneous radiofrequency ablation (RFA) is effective in the management of hepatocellular carcinoma (HCC) that has poor conspicuity at conventional sonography.
AIM: To evaluate the long-term natural history of the gastroduodenal lesions secondary to extrahepatic embolization with Ytrium 90 (90Y) spheres.
Biliary tract complications are the most common complications after liver transplantation. These complications are encountered more commonly as a result of increased number of liver transplantations and the prolonged survival of transplant patients. Biliary complications remain a major source of morbidity in liver transplant patients, with an incidence of 5%-32%. Post liver transplantation biliary complications include strictures (anastomotic and non-anastomotic), leaks, stones, sphincter of Oddi dysfunction, and recurrence of primary biliary disease such as primary sclerosing cholangitis and primary biliary cirrhosis. The risk of occurrence of a specific biliary complication is related to the type of biliary reconstruction performed at the time of liver transplantation. In this article we seek to review the major biliary complications and their relation to the type of biliary reconstruction performed at the time of liver tranplantation.
AIM: To analyze whether high-intensity focused ultrasound (HIFU) ablation is an effective bridging therapy for patients with hepatocellular carcinoma (HCC).
Purpose: To prospectively assess the performance of hydrogel-coated versus fibered microcoils in the prophylactic occlusion of the gastroduodenal artery (GDA) before yttrium-90 (90Y) radioembolization.
Chronic kidney disease (CKD) is a worldwide public health problem. In the United States, between 1988-1994 and 2005-2010, the overall prevalence estimate for CKD, defined by an estimation of glomerular filtration rate <60 ml/min per 1.73m2 or a urine albumin-to-creatinine ratio ≥30 mg/g, rose from 12.3 to 14.0%. In 2010, overall per person per year costs for patients with CKD reached $22,323 for Medicare patients ≥65 years and older, and the overall Medicare expenditure for CKD was $41.0 billion, which consisted of 17% of the total Medicare dollars allocated.[1]
Purpose: To prospectively evaluate the efficacy of additional radiofrequency (RF) ablation by comparing the results of one and two sessions.
Purpose: To retrospectively review intermediate-term (median, 20.1 months) clinical outcomes after microwave ablation (MWA) of renal cell carcinoma (RCC).
Purpose: To retrospectively analyze the computed tomographic (CT) findings in a single-center series of adult patients with biopsy-proved obliterative portal venopathy (OPV) and to compare them with those observed in patients with cirrhosis.
Purpose: To demonstrate the feasibility of using chemical shift magnetic resonance (MR) imaging fat-water separation methods for quantitative estimation of transcatheter lipiodol delivery to liver tissues.
Purpose: To determine the feasibility of percutaneous microwave coagulation (PMC) for the treatment of small solitary breast cancers.
Purpose: To describe the preliminary safety and accuracy of a magnetic resonance (MR) imaging–guided high-intensity–focused ultrasound (HIFU) system employing new technical developments, including ablation control via volumetric thermal feedback, for the treatment of uterine leiomyomata with histopathologic correlation.
