Abstract
Hepatocellular Carcinoma (HCC) accounts for most primary cancers of the liver. Worldwide, it is the fifth most common cancer and the third cause of cancer related mortalities. The prevalence of HCC is high in Nile Delta area, and is more common in males, rural residents and farmers especially in HCV patients. To highlight the role of contrast enhanced MRI and diffusion magnetic resonance imaging in diagnosis of hepatocellular carcinoma (HCC). Contrast-enhanced magnetic resonance imaging (MRI) after bolus injection of gadolinium chelates is routinely used in many centers for the detection and characterization of hepatocellular carcinoma (HCC) lesions, mainly based on the increased arterial supply in most HCCs. Diffusion-weighted MRI (DWI) has recently gained interest in liver imaging, showing improved detection of liver lesions compared with T2-weighted imaging (T2WI), and enabling lesion characterization using apparent diffusion coefficient (ADC).
