Introduction. Hepatocellular carcinoma (HCC) is the fifth most common malignancy, with mortality ranking third among all malignancies. Data published by the Ministry of Health, Labor and Social Protection show that the incidence of primary HCC in Moldova is constantly increasing, in the last 10-15 years increasing by 3-3.5 times. Objective of the study. Comparison of CT and MRI values in the diagnosis of HCC and analysis of prognostic factors. Complex analysis of native and contrast-enhanced CT / MRI imaging examinations in order to determine the degree of tumor extension. Material and Methods. In a retrospective study, 200 patients with HCC were selected from January 2017 to January 2021 from the MCH „St Trinity” and the Medical Center „Euromed Diagnostic”. Equipment used: 64, 80, 128-slice spiral CT and 3.0 Tesla MRI. Iodinated contrast agent used on CT and gadolinium-based MRI. Results. MRI sensitivity was 81.82%, specificity 91.46%, positive predictive value 82.72%, negative predictive value 73.91%. CT examination showed a sensitivity of 66.33%, specificity of 90.85%, positive predictive value 75.71%, negative predictive value 62.35%. Differences in sensitivity and negative predictive value were statistically significant (p < 0.05). For specificity and positive predictive value, there was no statistical significance (p > 0.05). The diagnostic efficiency of MRI is better than that of CT diagnosis, but often complement each other. Performance was poor for HCC < 1 cm and had better results for HCC ≥ 2 cm. Conclusion. Assessment of HCC in complexity by imaging characteristics, including formation size, contour, number, vascular invasion, and mode of growth, allows for preoperative prediction and prognosis. |
