Imaging Characteristics of MRI in Diagnosis of Hepatocellular Carcinoma at E Hospital

Abstract

Our study of 40 patients with hepatocellular carcinoma (HCC) on Magnetic Resonance Imaging (MRI) at E Hospital indicated that the average age was 63.5 ± 10.8, most commonly from 50 - 70 years (57.5%). Most patients were male, with a male-to-female ratio of 12/1. One tumor accounted for 50%, and the right lobe liver tumor accounted for 57.5%. The size of mass 2 - 5 cm had the highest proportion (52.5%). While the percentage of increased signals on T2W was 87.5%, the proportion of decreased signals on T1W was 85%. Most patients had diffusion restriction on Diffusion with a rate of 92.5%. Besides, 100% of HCC strongly enhanced in the arterial phase, and 97.5% of HCC strongly washed out in the venous and late phases. Regarding other properties of HCC, portal vein thrombosis accounted for 22.5%, and arteriovenous malformation accounted for 2.5%.
