ABSTRACT
<p><b>OBJECTIVE</b>To investigate the hemodynamic changes of primary hepatocellular carcinoma (HCC) evolved from hepatic cirrhosis using CT perfusion imaging.</p><p><b>METHODS</b>Thirty-two patients with primary hepatocellular carcinoma evolved from virus-induced fibrosis or cirrhosis underwent dynamic CT scanning of the target slices for 60 min. The perfusion parameters of the hepatic parenchyma and HCC including the blood flow (BF), blood volume (BV), mean transit time (MTT), permeability-surface area product (PS), hepatic arterial fraction (HAF), IRF time of arrival (IRF TO) were obtained. Paired-sample t test was used to determine the differences in the perfusion parameters between the hepatic parenchyma and the primary HCC mass.</p><p><b>RESULTS</b>Compared with hepatic BF (117.13-/+31.05 ml/100 mg/min), BV (14.73-/+3.91 ml/100 mg), PS (31.93-/+5.91 ml/100 mg/min), HAF (25.02-/+8.19%), MTT (12.79-/+3.31 s), IRF TO (3.14-/+1.09 s), the primary HCC mass showed significant increments in the BF (239.69-/+96.07 ml/100 mg/min), BV (20.26-/+6.73 ml/100 mg), PS (37.50-/+9.50 ml/100 mg/min), HAF (68.97-/+15.22%) with decreased MTT (7.17-/+1.38 s) and IRF TO (2.42-/+0.94 s). Significant differences were found in all the perfusion parameters between the hepatic parenchyma and HCC (P<0.05).</p><p><b>CONCLUSION</b>Liver perfusion parameters can represent the hemodynamic changes in the HCC derived from hepatic cirrhosis.</p>
