Preoperative prediction of HCC microvascular invasion by multimodel peritumoral diffusion MRI

Objective

Most studies emphasize intratumoral diffusion-weighted imaging (DWI) metrics, but few studies have examined whether peritumoral DWI metrics can provide added value. We aimed to evaluate three-dimensional, multiscale, multimodel DWI parameters within intratumoral and peritumoral volumes of interest for predicting microvascular invasion (MVI) in hepatocellular carcinoma (HCC).
