ABSTRACT
Objective To research the value of CT perfusion imaging in diagnosing breast tumor .Methods 21 focuses in 17 cases withbreast tumorlike pathological changes diagnosed by molybdenum target examination were scanned by CT perfusion imaging . Cine model,0.5 s/circle ,5 mm in thickness?4,120 kV,60 mA,delayed time 10 s,scan time in all 50 s ,GE 4.2 workstation and perfusion 3 software were used ,the data of creating dynamic picture and the relative informations that image intention changes with time change were analyzed and every parameters related with perfusion were studied and analyzed statistically .Results Blood flow(BF),blood volume(BV),mean transit time(MTT) and permeability surface(PS) were (36.46?17.62)ml?min-1?100 g-1,( 13.76?8.59) ml/100 g,( 28.23?15.75) s and (16.45?12.36) ml?min-1?100 g-1.In cancer group,( 17.35?10.67)ml?min-1?100 g-1,( 4.63?3.47) ml/100 g,( 25.52?12.91) s and ( 3.57?3.36) ml?min-1?100 g-1 in benign lesion group,respectively,there was significant difference between two groups in BF,BV and PS(P
