  • Title: MR-guided percutaneous ethanol injection for hepatocellular carcinoma in a 0.2T open MR system.
    Author: Kim YJ, Raman SS, Yu NC, Lu DS.
    Journal: J Magn Reson Imaging; 2005 Oct; 22(4):566-71. PubMed ID: 16161074.
    Abstract:
    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.
