Sixty-four multi-slice computed tomography and magnetic resonance imaging in evaluation of hepatic focal lesions

Objective: The diagnostic accuracy of MSCT and MRI for evaluation of hepatic focal lesions. Design: An analytic comparative study. Setting: Radiology Department, Farwania Hospital. Subjects: Ninety-five hepatic focal lesions, 61 patients were examined from October 2006 to March 2010. Gold standard was biopsy, radiological and clinical follow up. Main outcome: The value of CT and MRI in characterizing these lesions was assessed. Results: The mean sensitivity of MRI was (72.5%) and CT (72.6%) in the detection of overall hepatic focal lesions. However, the positive predictive value for MRI was 96.1% and for CT was 91.5%. False negative results were the problem of MRI and CT in lesions ≤2 cm (33.8% and 30.5%, respectively). About lesion characterization, MRI was relatively highly specific for diagnosis of HCC (87.5%), hemangioma (91.2%) and metastases (87.8%).
