Abstract

Magnetic resonance imaging (MRI) plays an important role in the early detection of benign or malignant liver lesions. Hepatobiliary contrast agents increase the accuracy of MRI in the differential diagnosis of focal liver lesions and reduce the number of unspecified liver lesions. Objective: To evaluate the role of MRI using Primovist acid in the diagnosis of focal liver lesions that are difficult to identify on computed tomography or ultrasonography. Subject and method: Study on 34 male and female patients, the average age was 56 (age) assigned to have MRI with Primovist contrast injection on MRI system 3.0T, discovery 750 (GE). Result: 34 patients, including 48 lesions, 28 hepatocellular carcinoma lesions (58.3%), focal nodular hyperplasia 5 (10.4%), neoplastic nodules 4 (8.3%), hemangiomas 2 (4.2%), metastasis 2 (4.2%), cholangiocarcinoma 1 (2.1%), parasites 1 (2.1%), other lesions 5 (10.4%) including liver abscess, infected cyst. There were 23 patients with a history of hepatitis B and/or cirrhosis (67.6%). Conclusion: The research shows that hepatobiliary contrast agents increases the diagnostic accuracy of MRI hepatocellular carcinoma in cirrhotic patients, small metastases, differentiation between focal nodular hyperplasia and adenoma, hemangiomas, dysplastic nodule and early-stage hepatocellular carcinoma.
