Role of Triphasic MRI in the Evaluation of Focal Hepatic Lesions with Histopathological Correlation

Abstract

Pathologies of hepatic lesions ranges from benign lesions like hemangioma, hepatic adenoma and cyst to malignant lesions like primary hepatocellular carcinoma and metastases. In the clinical context, focal hepatic lesions are a daily challenge. Non-invasive diagnosis of liver abnormalities is typically accomplished using contrast- enhanced Magnetic Resonance (MR) imaging. Due to its higher soft tissue resolution, multiplanar capability and lack of radiation triphasic MRI has recently proven to be the ideal approach for the evaluation of focal hepatic lesions. This study aimed to determine the role of triphasic MRI in the evaluation of focal hepatic lesions and their correlation with histopathological findings. This study was carried out in the Department of Radiology and Imaging, BSMMU, Dhaka. The study was conducted among patients with focal hepatic lesions during the period from the date of September 2021 to August 2023 on 48 patients. Triphasic MRI were done then findings compared with the histopathology findings. Sensitivity, specificity and accuracy were calculated for diagnostic validity of triphasic MRI. In this study observed that majority (27.1%) of the patients belonged to age 51-60 years. The mean age was found 49.7±13.8 years with range from 20 to 73 years. Almost two third (64.6%) of the patients were male and 17(35.4%) patients were female, male female ratio was 1.8:1. Malignant lesions were found 33(68.8%) patients and benign lesions were 15(31.3%). Most common malignant lesion was HCC followed by metastasis and benign lesion was hemangioma followed by hepatic adenoma, hepatic cyst. Triphasic MRI has high sensitivity and specificity in the evaluation of the focal hepatic lesions. Triphasic MRI detects and characterizes focal hepatic lesions by their characteristic appearance and specific contrast enhancement patterns. It has several advantages like multiplanar capability, higher soft tissue contrast and lack of ionizing radiation.
