Objective To explore the stability of perfusion parameters by comparing the perfusion parameters between original images and cutting the half of original images.Methods Totally of 28 cases underwent brain perfusion scan.All patients were scanned with cine scan 1.0smode,and were continuous scanning for 50 s.The original images were defined as A group and the group which were cut the half of original images were as B group.The perfusion parameters such as mean transit time(MTT),cerebral blood flow(CBF),and cerebral blood volume(CBV)were measured and compared in the area of cerebral gray matter,lenticular nucleus and cerebral white matter.Results The MTT were significant lower in A group than B group in the area of cerebral gray matter,lenticular nucleus and cerebral white matter(all P0.05);the CBF were significant higher in A group than B group in the area of cerebral gray matter,lenticular nucleus and cerebral white matter(all P0.05);CBV had no statistical significant between A group and B group.Conclusion The different ways of brain perfusion scan would get to different perfusion parameters,especially the MTT and CBF.
