ABSTRACT

Introduction: Until the end of the 20th century, diffuse liver disease was a difficult diagnosis through imaging methods and its confirmation was only possible with liver biopsy and its histopathologic result. Currently, advanced MRI techniques can make possible a more reliable diagnosis of these diseases with a non-invasive technique, compared to other imaging methods and diagnostic modalities. Objective: To describe the magnetic resonance imaging (MRI) findings of various diffuse liver diseases. Methods: A descriptive case series was performed with patients with diffuse liver disease who attended a health care institution specialized in MRI services. Results: There were four cases with cirrhosis of different etiologies: one caused by hepatitis B and hepatocellular carcinoma, and with an associated diffuse malignant thrombosis of the portal vein, another caused by hepatitis C, the third of vascular origin (congestive), and a case of alcoholic cirrhosis. Similarly two other cases were evaluated for steatosis, one with a focal non-infiltrative area and one with generalized fatty liver infiltration. In addition, a secondary hemochromatosis case was analyzed. Conclusion: MRI becomes a non-invasive diagnostic tool that does not involve exposure to ionizing radiation, useful for preoperative evaluation and monitoring of diffuse liver diseases, regardless of its etiology.
