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.
