of normal liver parenchyma and most of the lesions is low

Old indications for NCCT

Hypervascular metastases

Quantification of liver iron in cases of hemochromatosis

Detection of confluent fibrosis in cirrhotic liver

Most of hepatic deposits are hypovascular

Hepatic neoplasms receive most of their blood supply via hepatic artery

Hypervascular deposits should be assessed by dual phase CT or dynamic MRI
