Abstract

Objective: assess the value of Magnetic Resonance Imaging (MRI) in the diagnosis of primary hepatocellular carcinoma (HCC) at E hospital. Methods: A cross-sectional descriptive study was conducted, including retrospective and prospective data collection from 36 patients with liver tumor: 27 patients with HCC, 9  non-HCC  patients  (4 patients  with  liver  metastasis, 3 patients with adenoma, 1 patients with dysplastic nodule, 1 patients with cholangicarcinoma) at E Hospital from January 2023 to June 2025 and comparison with the pathological results. Data analysis was performed using SPSS 25.0 software. Results: The average age was 65.8 ± 9.8 years, with most patients 50 - 70 years old. The mean ADC for liver tumor was 1.087  ± 0.200 (x10^-3mm²/s), HCC was 1.075  ± 0.123 (x10^-3mm²/s). To differentiate HCC from other lesions, the area under the ROC curve is 0.424. The accuracy of MRI in the diagnosis of primary hepatocellular carcinoma was 92.6% sensitivity, 88.9% specificity, and 96.2% positive predictive value. Conclusion: MRI is very valuable in diagnosing HCC with high sensitivity and specificity. Complete analysis and characterization of MRI images is essential to optimize HCC diagnosis.
