Differentiation of malignant thrombus from bland thrombus of the portal vein in patients with cirrhosis: Application of intravoxel incoherent motion diffusion-weighted MR imaging

The intravoxel incoherent motion (IVIM) MR imaging can distinguish bland thrombus from neoplastic thrombus in the portal vein in patients with cirrhosis or hepatocellular carcinoma. Pseudo-diffusion coefficient (micro-perfusion) of neoplastic thrombus was significantly higher than that of bland thrombus, which might be due to capillary blood flow within neoplastic thrombus.
