QSM imaging can be considered a potential technique for noninvasive preoperational assessment of MVI in hepatocellular carcinoma. 
Table1. The susceptibility of tumorous and peritumoral from MVI+ and MVI− HCC.
Figure1. Hepatectomy pathological confirmed hepatic carcinoma (Yellow arrow) with MVI− (Top row) and MVI+ (Bottom row). ROIs were placed on the maximal slice of tumor (red zone) and peritumor (green zone). The tumorous and peritumoral susceptibility of HCC with MVI− and MVI+ was -0.12 ppm, -0.09 ppm, 0.13 ppm, 0.16 ppm, respectively.
