Multi-parametric MRI is becoming the gold standard for assessing hepatic tumor response to intra-arterial therapy. We present the MR-ONCO-TREAT software package for 3D evaluation of multi-parametric MR studies. The software includes: deformable image registration, interactive segmentation, and volumetric and functional analysis. In six patients with hepatocellular carcinoma, this software was able to register pre and post intra-arterial treatment MRI scans, segment tumor from surrounding liver, and provide volumetric and functional data analysis. On average, percent arterial enhancement decreased by 35.7, and the ADC increased by 9.5%. The MR-ONCO-TREAT software can automate the evaluation of hepatic tumors, possibly decreasing interpretive errors.
