AMERICAN JOURNAL OF ROENTGENOLOGY. MR Angiography at 3 T of Peripheral Arterial Disease: A Randomized Prospective Comparison of Gadoterate Meglumine and Gadobutrol

Christian Loewe, Javier Arnaiz, Denis Krause, Luis Marti-Bonmati and Stefan Haneder, Ulrich Kramer for the DALIA study group

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).

AMERICAN JOURNAL OF ROENTGENOLOGY. Chemoembolization of Recurrent Hepatoma After Curative Resection: Prognostic Factors

Qing-Quan Zu, Sheng Liu, Chun-Gao Zhou, Zheng-Qiang Yang, Jin-Guo Xia, Lin-Bo Zhao and Hai-Bin Shi

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.

AMERICAN JOURNAL OF ROENTGENOLOGY. Intraductal Cooling via a Nasobiliary Tube During Radiofrequency Ablation of Central Liver Tumors Reduces Biliary Injuries

Ely R. Felker, Stephanie A. Lee-Felker, Khobkhoon Ajwichai, Nelly Tan, David S. Lu, Francisco A. Durazo and Steven S. Raman

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.

RADIOLOGY. Small Hepatocellular Carcinoma: Radiofrequency Ablation versus Nonanatomic Resection—Propensity Score Analyses of Long-term Outcomes

Tae Wook Kang, MD, Jong Man Kim, MD, Hyunchul Rhim, MD, Min Woo Lee, MD, Young-sun Kim, MD, Hyo Keun Lim, MD, Dongil Choi, MD, Kyoung Doo Song, MD, Choon Hyuck David Kwon, MD, Jae-Won Joh, MD, Seung Woon Paik, MD, Yong Han Paik, MD, Joong Hyun Ahn, PhD

Purpose: To compare radiofrequency (RF) ablation with nonanatomic resection (NAR) as first-line treatment in patients with a single Barcelona Clinic Liver Cancer (BCLC) stage 0 or A hepatocellular carcinoma (HCC) and to evaluate the long-term outcomes of both therapies.

EUROPEAN JOURNAL OF RADIOLOGY. Feasibility of intermittent pneumatic compression for venous thromboembolism prophylaxis during magnetic resonance imaging-guided interventions.

Majid Maybody, Bedros Taslakian, Jeremy C. Durack, Elena A. Kaye, Joseph P. Erinjeri, Govindarajan Srimathveeravalli, Stephen B. Solomon

Purpose: Venous thromboembolism (VTE) is a common cause of morbidity and mortality in hospitalized and surgical patients. To reduce risk, perioperative VTE prophylaxis is recommended for cancer patients undergoing surgical or interventional procedures. Magnetic resonance imaging (MRI) is increasingly used in interventional oncology when alternative imaging modalities do not adequately delineate malignancies. Extended periods of immobilization during MRI-guided interventions necessitate an MR compatible sequential compression device (SCD) for intra-procedural mechanical VTE prophylaxis. Such devices are not commercially available.

EUROPEAN JOURNAL OF RADIOLOGY. Drug-eluting versus plain balloon angioplasty for the treatment of failing dialysis access: Final results and cost-effectiveness analysis from a prospective randomized controlled trial (NCT01174472).

Panagiotis M. Kitrou, Konstantinos Katsanos, Stavros Spiliopoulos, Dimitris Karnabatidis, Dimitris Siablis

Objective: To report the final results and cost-effectiveness analysis of a prospective randomized controlled trial investigating drug-eluting balloon (DEB) versus plain balloon angioplasty (BA) for the treatment of failing dialysis access (NCT01174472).

EUROPEAN JOURNAL OF RADIOLOGY. Transarterial chemoembolization in soft-tissue sarcoma metastases to the liver – The use of imaging biomarkers as predictors of patient survival.

Julius Chapiro, MD, Rafael Duran, MD, MingDe Lin, PhD, Benedetto Mungo, MD, Todd Schlachter, MD, Rüdiger Schernthaner, MD, Boris Gorodetski, BS, Zhijun Wang, MD, PhD, Jean François Geschwind, MD

Background: The clinical management of patients with metastatic soft-tissue sarcoma of the liver is complicated by the paucity of reliable clinical data. This study evaluated the safety profile, survival outcome as well as the role of imaging biomarkers of tumor response in metastatic soft-tissue sarcoma (mSTS) of the liver treated with conventional transarterial chemoembolization (cTACE).
