Comparative diagnostic value of contrast-enhanced ultrasonography, computed tomography, and magnetic resonance imaging in diagnosis of hepatic hemangiomas
Abstract
Material and methods. The study enrolled 48 patients, aged between 20 and 79 years (35 [72.9%] women, 13 [27.1%] men; mean age, 53.5±12.855 years), who were examined and treated in the Departments of Gastroenterology, Surgery, and Oncology, Hospital of Kaunas University of Medicine, in the year 2007. All patients underwent intravenous contrast-enhanced US, intravenous contrast-enhanced CT, and MRI and were diagnosed with hepatic hemangioma according to the findings of these examinations.
Results. The size of hemangiomas was ≤2.0 cm in 20 cases (41.7%) and >2.0 cm in 28 (58.3%). No association between hepatic hemangioma and patient’s age was found (χ2=0.547, df=2, P=0.761). Nearly one-third of hemangiomas were located in the segment IV of the left hepatic lobe. There were a few complicated hemangiomas in the study sample: 2 with calcification and 1 with necrosis. The sensitivity of CT in the diagnosis of hepatic hemangioma was 76.92%; specificity, 33.3%; positive prognostic value, 83.3%; and negative prognostic value, 25.0%. The sensitivity of intravenous contrast-enhanced US in the diagnosis of hepatic hemangioma was 77.8%; specificity, 100%; positive prognostic value, 100%; and negative prognostic value, 23.1%.
Conclusions. Intravenous contrast-enhanced US is more specific than intravenous contrast-enhanced CT in the diagnosis of hepatic hemangioma (P=0.0005) and has a higher positive prognostic value (P=0.001).
