EVALUATION OF LIVER LEISONS ON BIPHASIC COMPUTED TOMOGRAPHY (CT) SCAN- AN OBSERVATIONAL STUDY

Purpose: The purpose of this study was to evaluate liver lesions on dual phase computed tomography scan (CT scan) especially in the HCV patients having cirrhotic liver. One of the significant aspects is to improve the diagnostic facility for hepatocelluar carcinoma (HCC), besides its prevention. Early stage diagnosis is helpful in asymptomatic patients where liver function remains preserved. It also provides better opportunities for tumor treatment via medications and radio therapy.  Radio imaging is an imperative tool to diagnose HCC in early stages. HCC shows typical vascular enhancement on arterial phase in CT scan and MRI, and washout in venous phase. This review summarizes the current knowledge about imaging techniques for early diagnosis and staging of HCC. Primary hepatocellular carcinoma is among 10 most common tumors, and is one of the most common primary liver malignancies in the world. Method and material: 130 patients were evaluated on ultrasound to have liver defect. 106 were confirmed to possess liver lesions that were evaluated on biphasic CT scan. After maintaining the IV line, injection was injected through pressure injector and acquisition was started. At 15-20 sec arterial phase was taken and at 50-60 second portal venous phase was taken. Result: Out of 106 patients, 64.71% possessed hepatocecullar carcinoma along with HCV and cirrhotic liver. The patients diagnosed with HCC were 23.53%. The percentage of patients diagnosed with HCC together with HCV was same as patients having HCC and cirrhotic liver i.e., 5.88%. Conclusion: Biphasic computer tomography is a great diagnostic tool for the detection of liver lesions where lesion conspicuity is dependent on vascularity of the lesion.
