ABSTRACT
OBJECTIVE@#To investigate the application of CT hepatic volume measurement combined with CT perfusion imaging (CTPI) by Spiral CT in evaluating the hepatic functional reserve in cirrhosis.@*METHODS@#CT volume measurement of livers was performed in 32 patients with cirrhosis and 20 patients with normal livers. CTPI had been taken in 25 patients with cirrhosis and 20 patients with normal livers. The hepatic volume, parameter of blood flow perfusion, and liver volume-perfusion index were observed and analyzed. Correlations between graded fractions of hepatic function and liver volume, parameter of perfusion, and liver volume-perfusion index were also analyzed.@*RESULTS@#The values of liver volumes (LV, LVs) reduced gradually (P<0.01) among the groups of hepatic function Grade A, B, and C. The values of the hepatic portal perfusion (HPP), total liver perfusion (TLP), hepatic arterial perfusion index (HAI), and portal perfusion index (PPI) of the cirrhosis group were significantly lower than those of the normal ones (P<0.01). The values of the HPP reduced gradually among Grade A, B, and C (P<0.05 or P<0.01). The values of PPI reduced significantly between Grade C and Grade A, B (P<0.05 or P<0.01). The liver volume-perfusion indexes (VPI, VPIs, VPPI, VPPIs) reduced gradually among Grade A, B, and C (P<0.05 or P<0.01). The correlation between liver volume-perfusion indexes and graded fractions of hepatic function was higher than other indexes, among which the correlation of VPPIs was the highest.@*CONCLUSION@#Changes of volume and blood flow perfusion of the liver are related to the clinical grade of hepatic function. The CT volume measurement combined with CTPI will be a more comprehensive way in evaluating hepatic functional reserve.
