Role of Dynamic Contrast Enhanced MRI in Evaluation of Focal Hepatic Lesions

ABSTRACT

Background: CMost of the focal hepatic lesions in day to day practice can be diagnosed by cross sectional contrast enhanced studies. The present study evaluates the role of dynamic contrast enhanced MRI for detection & characterization of these lesions commonly found in our area. Methods: It’s a perspective study of 50 patients with all age groups who were suspected clinically to have focal hepatic lesions or diagnosed so by ultrasonography or computed tomography. The patients underwent MRI including dynamic contrast enhanced sequences, which included i.v. administration of the contrast material (Gadopentate dimeglumine). The results of the MRI were confirmed by various confirmatory methods depending upon the lesion in question. Results & Conclusions: Overall sensitivity of MRI in detection of focal hepatic lesions was 100% while its specificity was 98%. Comprehensive MR imaging examination yields characteristic enhancement patterns that can be used to diagnose or at least narrow the differential diagnosis for most of these lesions
