Hepatocellular carcinoma: Findings on spiral CT during arterial portography

Abstract

The presence of a low attenuated homogeneous intrahepatic mass with associated vascular invasion on SCTAP scans should raise the possibility of HCC. The presence of spontaneous portosystemic shunts is associated with poor or moderate parenchymal enhancement.

MR Imaging of Hepatic Metastases

“…Besides MR, preoperative imaging modalities in- CT during arterial portography (CTAP) has been used for decades as a gold standard for liver lesion detection. CTAP was found to be particularly effective for the identification of small hepatic lesions (24,25). Localized alterations in perfusion, however, resulted in frequent false-positive findings with this method.…”

Liver tissue sparing resection using a novel planning tool

“…Although the frequency of hepatic resection is increasing, hepatectomy remains one of the most difficult operative procedures because of anatomical complexity and hepatic vascular variability [1][2][3]. Furthermore, many patients with hepatocellular carcinoma suffer from chronic liver disease such as cirrhosis, resulting in impaired hepatic function that necessitates restriction of liver resection volume [4].…”
