Background Hepatic focal lesions may be benign or malignant and some of the hypervascular focal lesions may be benign. Therapy requires an accurate diagnosis, which in turn relies primarily on appropriate imaging and image-guided biopsy. Objectives The purpose of this study is to study the role of MRI in characterization of hypervascular hepatic focal lesions in cirrhotic patient on unenhanced, dynamic contrastenhanced and diffusion weighted MR images for better patient management plan. Patients and Methods This study was conducted at Radiology department at Ain Shams University hospitals. About 70 patients were included (17 females &amp; 53 males) and their age ranged from 14 to 87 years. Results DW MRI in the liver is a relative new and increasingly used imaging technique. It has the advantage that it can be obtained during a single breath-hold; it provides unique information that reflects tissue cellularity and organization. The ADC maps can also provide quantitative measurements of tissue water diffusibility, which can be used not only for disease assessment, but also for the evaluation of disease response to treatment. Conclusion Conventional MRI sequences combined with dynamic MRI and DWI provide further more accurate diagnoses for hepatic focal lesions, especially for hypervascular hepatic focal lesions which requires the necessity for injecting the contrast material and through the different pattern of enhancement and washout, we could be able to reach the definite diagnosis for these hepatic focal lesions and so stating management as early as possible which reflect on increasing the prognostic criteria for hepatic focal lesions.
