Abstract
Multiple imaging techniques are used for liver imaging, like ultrasound, CT, and MRI. Ultrasound is still the first-line method of choice, CT and MR are applied when focal hepatic lesion is suspected.
CT remains the main technique for imaging focal hepatic lesions, with increasing use of spiral CT diagnostic accuracy could be dramatically enhanced.
There is now an increased use of triphasic CT examination that further improve detection rates in certain tumors and may aid in lesion differentiation.
Hepatic arterial phase imaging increases detection of hypervascular tumor, like hypervascular primary hepatic tumors like hepatocellular carcinoma, hemangioma, and focal nodular hyperplasia, and the hypervascular hepatic deposits.
Hypovascular lesions(like hypovascular deposit) are best detected in the portal venous phase.
The equilibrium phase help in detection of the lesions which retained contrast medium, or that shows fill in pattern of enhancement like hemangioma, which may shows nearly total or total opacification of the lesion at the equilibrium phase.
