Objective: To characterize hepatocellular carcinoma (HCC) in terms of perfusion parameters using volume perfusion CT (VPCT) and two different calculation methods, compare their results, look for interobserver agreement of measurements and correlation between tumor arterialization and lesion size.
Purpose: To investigate the impact of intra-tumoral fat detected by chemical-shift MR imaging in predicting the MVI of HCC.
Objectives: To evaluate the clinical feasibility of dual-source dual-energy CT angiography (DSDECTA) with virtual non-enhanced images and iodine map for active gastrointestinal bleeding (GIB).
OBJECTIVE. The purpose of this study was to report the effectiveness and safety of selective arterial embolization for the management of anticoagulation-related soft-tissue bleeding.
OBJECTIVE. This large-scale randomized study aimed to show the noninferiority in terms of diagnostic performance of gadoterate meglumine–enhanced versus gadobutrol-enhanced 3-T MR angiography (MRA) using digital subtraction angiography (DSA) as the reference standard in patients with peripheral arterial occlusive disease (PAOD).
OBJECTIVE. The long-term prognosis after hepatic resection for the treatment of hepatocellular carcinoma (HCC) has been disappointing because of the high recurrence rates in the remnant liver, which constitutes the major cause of death. The purpose of this study was to identify the prognostic factors for overall survival after transarterial chemoembolization (TACE) in recurrent HCC after the initial curative surgical resection.
OBJECTIVE. The objective of our study was to determine the safety and efficacy of intraductal perfusion of chilled 5% dextrose in water (D5W) via an endoscopic nasobiliary tube (NBT) for the prevention of thermal bile duct injury in patients undergoing percutaneous radiofrequency ablation (RFA) of central liver tumors.
Purpose: To assess the feasibility and accuracy of digital breast tomosynthesis (DBT)–guided needle localization for DBT-detected suspicious abnormalities not visualized with other modalities and to analyze the imaging and pathologic characteristics of abnormalities detected only with DBT to determine the positive predictive value for malignancy.
Purpose: To determine whether changes in coronary opacification normalized to the aorta (corrected coronary opacification [CCO]) across stents can help identify in-stent restenosis (ISR) severity with use of invasive coronary angiography as the standard of reference.
Purpose: To test and compare the association between radiologic measurements of lesion diameter, volume, and enhancement on baseline magnetic resonance (MR) images with overall survival and tumor response in patients with unresectable hepatocellular carcinoma (HCC) treated with transarterial chemoembolization (TACE).
Purpose: To compare the long-term outcomes of repeated hepatic resection and radiofrequency (RF) ablation for recurrent hepatocellular carcinoma (HCC) by using propensity score matching.
Purpose: To compare long-term survival after hepatic resection and transarterial chemoembolization of large solitary hepatocellular carcinomas (HCCs).
Purpose: To evaluate the clinical feasibility and diagnostic accuracy of three-dimensional (3D) quantitative magnetic resonance (MR) imaging for the assessment of total lesion volume (TLV) and enhancing lesion volume (ELV) before and after uterine artery embolization (UAE).
Purpose: To evaluate national trends in percutaneous hepatic and renal biopsy procedures with regard to utilization, specialty group roles, and sites of service.
Purpose: To investigate the prognostic value of R.E.N.A.L. (radius, exophytic/endophytic, nearness to collecting system or sinus, anterior/posterior, and location relative to polar lines) nephrometry score after percutaneous ablation of renal cell carcinoma (RCC).
