Objective To implore methods of perfusion imaging in body tumor with 64-slice CT and its clinical application value Methods 12 patients with body tumor underwent perfusion imaging with 64-slice CT.At first,plain CT scan was performed to localize central slice of tumor,then perfusion imaging of body tumor was done using slice thick 28.8 mm·(4 i)-1,injecting dosage 40-50 ml,injecting rate 6 ml·s-1,scaning delay time 8-10 s,scaning total time 35-40 s.All scaning images was transferred into Simens workstation to be processed by Syngo soft,to get color-coded map,including blood flow(BF),blood volume(BV) and permeability surface(PS).Result Perfusion images of all body tumor can get a wonderful color-coded map,the pattern of tumor in blood flow and blood volume and permeability showed remarkeable increase except for pancreatic tumor.Conclusion 64-slice CT perfusion imaging,a novel modality,provides a valid and repeated way to quantitatively estimate blood perfusion status in body tumor.
