Role of Triple Phase MDCT in the Characterisation of Liver Lesions

Abstract

BACKGROUNDMDCT is a very useful investigative technique for all liver pathologies. The conspicuity of a liver lesion on CT depends on the attenuation difference between the lesion and the normal liver. The difference in blood supply results in different enhancement patterns between various liver tumours in the various phases of contrast enhancement. Intravenous contrast is needed to increase the conspicuity of lesions. Multidetector computed tomography with plain, arterial, portal venous and delayed phase is very useful in identifying and characterising various liver lesions depending on their vascular nature. In our study, we evaluated the role of Multidetector computed tomography in the characterisation of liver lesions in patients presenting to our hospital.
