Abstract Background Differentiation between malignant and bland thrombus of the portal vein in patients who have HCC using diffusion weighted MR imaging. Objective To determine the role of DW imaging in differentiating between the benign and malignant portal vein thrombosis in patient with HCC. Patients and Methods This is a retrospective study done in ain-shams hospitals and private centers. This is a retrospective study done in Ain-Shams Hospitals and private centers. We studied 20 cases, 13 males and 7 females with total mean age 59.5. Results Our study had some limitations. First, we did not use pathologic findings as our reference standard for characterizing the thrombi; instead, we have used accepted imaging criteria as a reference standard. In our study, we used oval ROI placement and although we avoided averaging ADC of the thrombus with the surrounding structures “by enlarging the images and placing the ROI within the thrombus “, we cannot completely exclude that some averaging could have occurred in the smallest thrombi. Conclusion In addition to the initial diagnosis of the PVT nature, subsequent contrast-enhanced MRI is actually necessary to evaluate further treatment response in daily routine. But the administration of I.V. contrast agent is problematic especially in patients with renal insufficiency. Therefore, DWI technique can be utilized in adjunction with routine MRI protocols to determine the nature of PVTs by the calculation of ADCs values.

Contrast-enhanced ultrasound (CEUS) is a simple, safe and reliable technique for the clinical management of patients with various liver diseases. Although the major target of the technique may be focal hepatic lesions, it is also effective for the diagnosis of non-tumor liver diseases, such as grading hepatic fibrosis, characterization of chronic liver diseases and diagnosis of portal vein thrombosis. This review article aimed to overview the recent application of CEUS in the assessment of non-tumor liver diseases.
