Abstract

Introduction:
HCC represents > 90% of primary hepatic tumors. It ranks as the 5th most common cancer worldwide and the 2nd leading cause of death among male patients after lung cancer. The diagnosis of HCC is made nowadays by non-invasive criteria where imaging studies play main role. HCC has tendency for microvascular invasion with invasion of portal vein being reported in 35%-50% of HCC cases. Concomitant bland and malignant PVT coexist as well. The differentiation between bland and malignant PVT is crucial as it’s hugely implicated in the diagnosis, staging, prognosis of the disease, and the treatment plans. DW MRI is an emerging non invasive imaging technique, that doesn’t need contrast administration. It’s very sensitive in tissue characterization and can be used to differentiate between bland and malignant PVT.
Aim of the work:
To evaluate the role of DW MRI in combination with mean ADC values in differentiating between bland and malignant portal vein thrombus.
