title: [Features of eight segments of liver perfusion with the second generation dual-source computed tomography].
abstract: OBJECTIVE
  To explore the features of eight segments of liver perfusion with the second generation dual-source computed tomography (DSCT) .
  
  
  METHODS
  Totally 15 patients with pancreatic endocrine diseases underwent abdominal CT perfusion with the second generation DSCT. The liver perfusion images were then transferred to workstation, and perfusion parameters were calculated, and then the artery liver perfusion (ALp) , portal-vein liver perfusion (pVp) , and hepatic perfusion index (HpI) of the eight hepatic segments were calculated.
  
  
  RESULTS
  ALp was significantly different between segments 3, 4 and segments 5-8 (P<0.05) . pVp was significantly different between segments 2 and segments 6, 7 (P<0.05) . pVp and HpI were significantly different between segment 3 and segments 5-8 (P<0.05,P<0.01) .
  
  
  CONCLUSIONS
  The second generation DSCT can be used to evaluate the perfusion conditions in all eight hepatic segments. The perfusion differs among eight segments of liver, which may be related with the anatomy of the liver vessels and the position of DSCT scanning. Its clinical significance needs further research.
