Evaluation of Hepatocellular Carcinoma Tumor Response After Transcatheter Arterial Chemoembolization Using Gadobenate Dimeglumine-Enhanced Liver Magnetic Resonance.

Objective: Use of gadobenate dimeglumine-enhanced liver magnetic resonance (MR) for evaluation of hepatocellular carcinoma tumor response after transcatheter arterial chemoembolization (TACE).

Methods: Forty-five patients with hepatocellular carcinoma were imaged with multiphase gadobenate dimeglumine-enhanced MR examination at baseline and 1-month follow-up after TACE. Nodule size, enhancement, and apparent diffusion coefficient were measured for both examinations by 2 reviewers.
