Abstract:
The unique dual blood supply of the liver makes it one of the common sites for various vascular neoplastic and non-neoplastic diseases. Increasing use of multiphase contrast-enhanced computed tomography (CT) and dynamic magnetic resonance imaging (MRI) has led to increased identification of numerous non-neoplastic vascular entities apart from already well-known neoplastic lesions. The objective of this review is to describe the causes and clinical features and to familiarize the reader with the key imaging features of various non-neoplastic vascular diseases affecting the liver. Non-neoplastic vascular diseases are classified broadly as those affecting the hepatic veins, portal veins, hepatic artery, intrahepatic shunts, and other miscellaneous conditions.

MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
