There is a substantial clinical need to identify patients who benefit from PVE procedure before undergoing major liver surgery. Elevated liver fat fraction is a frequent finding on pre-procedural MRI based on increasing rates of (non-) alcoholic fatty liver disease as well as chemotherapy-associated steato-hepatitis. Therefore, it was this studys aim to investigate the correlation of MRI-based liver fat fraction on hypertrophy rates after PVE.Including patients with colorectal liver metastases undergoing a single type of portal vein occlusion only there was no correlation found indicating that MRI-based high liver fat fraction should not discourage to perform PVE.
