Abstract: Introduction: The increasing and widespread use of imaging studies has led to an increase in detection of incidental Focal Liver Lesions. It is important to diagnose not only malignant liver lesions, but also benign solid and cystic liver lesions. The non-invasive diagnosis of liver lesions is usually achieved with contrast material-enhanced computed tomography and Magnetic Resonance (MR) imaging. Dynamic three dimensional gradient-recalled-echo MR imaging provides dynamic contrast-enhanced thin-section images with fat saturation and a high signal-to-noise ratio and is excellent for the evaluation of various focal hepatic lesions. Objectives: Role of MRI imaging in characterization and differentiation of various focal liver lesions detected incidentally on Ultrasonography. Methods: This was a multicentric/single center study conducted on In patients and Outpatients of Pandit Deendayal Upadhyay Medical College and Hospital, Rajkot. The present study included 50 patients with various focal Liver Lesions detected incidentally on Ultrasonography. MRI Liver of the patients having incidentally detected Focal Liver Lesions on Ultrasonography and Inconclusive Ultrasonography findings was done to characterize the various focal liver lesions. Pathological and post-operative histopathological findings were noted. Microsoft excel software was used for data analysis and tables were prepared for comparison of collected data. Result: Of the 50 patients, 30 patients were male and 20 were female. Age of patients ranged from 5 year to 78 years. Spectrum of diseases based on imaging findings includes: Hepatic cyst (5/50, 10%), Hemangiomas (7/50, 14%), Focal nodular hyperplasia (2/50, 4%), Hydatid cyst (2/50, 4%), abscess (2/50, 4%), hepatocellular carcinoma (11/50, 22%), metastases (9/50, 18%) and others (12/50, 24%). Metastasis and Hepatocellular Carcinoma (HCC) were most common malignant lesions in liver while Hemangiomas were most common benign lesions followed by simple and complex cysts and hepatic adenoma. Conclusion: MRI has an excellent lesion detection rate. Nearly all the lesions detected on Ultrasonography were detected on MRI imaging. MRI is excellent for the characterization and differentiation of various Focal Liver Lesions. It was possible to reach to a specific radiological diagnosis in most of the patients.
