Incremental dynamic CT for small hepatic tumours using high-speed, high-resolution CT apparatus

Incremental dynamic CT with a high-speed, high-resolution CT apparatus was utilized in four patients with small hepatic tumors. These tumors were imaged as minute, high-density regions, but were difficult to detect because they resembled transverse sections of the portal vein or were located immediately beneath the surface of the liver. Nevertheless, incremental dynamic CT with high-speed CT apparatus, with careful scrutiny and evaluation, can be applied as a means of screening for small hepatic tumors.
