Description

Highlights: • Enhancement accurately differentiates benign from malignant portal vein thrombus. • High accuracy is achieved at arterial, portal venous, and delayed phase imaging. • Subtracted and nonsubtracted images demonstrate similarly high diagnostic accuracy. • Sensitivity and specificity of 20% enhancement on subtracted later phases was >90%. - Abstract: Purpose: To evaluate MR imaging parameters including quantitative multiphasic post-contrast enhancement with subtraction and qualitative diffusion weighted imaging (DWI) in differentiating benign versus malignant portal venous thrombosis (PVT) in patients with hepatocellular carcinoma (HCC).
