[Investigations of the blood supply of liver tumors--computerized tomography]

The basic imaging method worldwide for the evaluation of the liver tumors before surgery and interventional treatments is spiral CT. CT is rapid, sensitive and accurate modality compared to US and it has become available in the past years in Hungary. Multislice CT represents further technical development which significantly shortened the examination time and CT-angiography can be performed at the same time with the evaluation of the liver parenchyma. CT should be performed prior guided biopsy in order to detect, to localize and to characterize all liver masses before the introduction of treatments. The follow up and the monitoring of the liver tumors after treatment is only reliable using the same type radiological studies which are performed on same way.
