Figure 2From: Three-dimensional whole-liver perfusion magnetic resonance imaging in patients with hepatocellular carcinomas and colorectal hepatic metastases Example of evaluation for perfusion parameter by the Tissue 4D tool. T1 map is automatically calculated by the precontrast images (upper left),and region of interest(ROI) is drawed covering the tumor on the dynamic contrast phases (upper right), then the time-intentsity curve is automatically calculated(lower right).Finally the colored-code parametric map of MR perfusion is generated(lower left).Back to article page
