The purpose of this work is to describe our experience with single‐session percutaneous ethanol injection (PEI) under the guidance of 0.2‐T open MRI for hepatocellular carcinomas (HCC) that were not suitable for ablation under ultrasound (US) or computed tomography (CT) guidance. None of the lesions (N = 7) were detectable on US. MRI was chosen over CT as the guidance modality because the nodules were located in the hepatic dome (N = 4) or were invisible on noncontrast CT (N = 3). All of the nodules were targeted successfully, and apparently complete tumor necrosis was achieved in six nodules (86%). During a follow‐up of one to 41 months, only one patient developed local recurrence four months after PEI. MR‐guided PEI is feasible and effective for treating HCC when other imaging guidance methods are not appropriate. J. Magn. Reson. Imaging 2005. © 2005 Wiley‐Liss, Inc.
