Evaluation of Hepatic Mass by Triple Phase Computed Tomography and Its Comparison With Fine Needle Aspiration Cytology in a Tertiary Care Hospital of Tripura

Liver is more prone to various neoplastic lesions including benign and malignant ones, because of rich blood supply by hepatic artery and portal vein. Normally blood supply to liver is mainly by the portal vein (70%), however most of the liver tumors receive their blood from the hepatic artery. These differences in pattern of blood ow form the basis of triple phase CT scan of liver and also differentiate the imaging features of primary and metastatic liver lesions. This cross-sectional study aims to nd out the diagnostic efcacy of Triple phase CT scan study in the evaluation of Hepatic mass lesions when compared with CT-guided FNAC. It was done over two years in the Department of Radiodiagnosis at Agartala Government Medical College & GBP Hospital, Tripura and 50 patients were studied. In Triple Phase CT diagnosis of Abscess, Sensitivity, Specicity, PPV, NPV and Accuracy was 100% on comparison with CT- guided FNAC. Whereas, in Triple Phase CT diagnosis of Metastasis, Sensitivity was 91.66%, Specicity was 100%, PPV was 100%, NPV was 92.85% and Accuracy was 96.0% on comparison with CTguided FNAC. On Triple Phase CT diagnosis of Hepatocellular Carcinoma, Sensitivity was 100%, Specicity was 93.3%, PPV was 90.9%, NPV was 92.85% and Accuracy was 96.0% on comparison with CT- guided FNAC.
