Prediction of microvascular invasion of hepatocellular carcinoma: value of volumetric iodine quantification using preoperative dual-energy computed tomography

摘要

Semiautomatic volumetric segmentation of the hepatocellular carcinoma (HCC). a HCC demonstrated in the mixed-energy images. b Readers manually draw a line across the maximum dimension of the tumor. c The software automatically segments the entire tumor volume. d Coronal reconstructed image shows the volumetric tumor segmented in three dimensions
