Abstract:
Background: To determine the value of triple phase CT scan and the phase acquisition in which maximum tumour conspicuity can be obtained, in a population of patients with chronic liver disease. Methods: In this descriptive study tripahsic CT scan of 50 chronic liver disease patients who presented with sonographic suspicion of space occupying lesion, were evaluated. CT scan appearances of different focal liver lesions , in arterial and portal venous phases, were evaluated . Tumour conspicuity was assessed on different phases of CT acquisition to determine the phase which provided maximum tumour to parenchymal difference, while using multidetector CT with fixed timing delay. Results: Focal hepatic lesion was found to be present in 41 out of 50 patients. 24 patients had morphological characteristics of hepatocellular carcinoma(HCC). Tumour was found to be most conspicuous in late arterial phase of acquisition in 30 patients Conclusion: Triphasic helical CT of liver, using early, late arterial and portal venous phases with fixed timing delays is quick, easy and non-invasive useful imaging modality in detection and characterization of focal lesions and especially diagnosis of HCC in cirrhotic patients.
