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

ObjectiveThe diagnostic accuracy of MSCT and MRI for evaluation of hepatic focal lesions.DesignAn analytic comparative study.SettingRadiology Department, Farwania Hospital.SubjectsNinety-five hepatic focal lesions, 61 patients were examined from October 2006 to March 2010. Gold standard was biopsy, radiological and clinical follow up.Main outcomeThe value of CT and MRI in characterizing these lesions was assessed.ResultsThe 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%).ConclusionAn analytic comparative study.
