A preliminary study about multi-slice CT perfusion imaging of normal adults' uteruses

Objective To explore the application of multislice CT perfusion imaging in uterus.Methods Routine pelvic CT was performed in 15 cases and then CT perfusion imaging was made at selecting slice.The contrast material was bolus injected through forearm superficial vein,while 4 slices of dynamic scan was performed for 40 seconds.The dynamic images were processed by Perfusion CT software package,and then the blood flow,blood volume and time to peak of the uterine body(n=13) and uterine cervix(n=6) were measured and documented respectively.Results All cases of multislice perfusion imaging were successfully performed.The blood flow,blood vol-ume and time to peak of the uterine body were(50.8±23.9) ml 100g-1 min-1,(13.3± 4.6)% and(18.3±7.2)s.The blood flow,blood volume and time to peak of the uterine cervix were(44.5±21.4) ml 100g-1 min-1,(10.0±4.7)% and(20.3±7.3)s.Conclu-sion Multislice CT perfusion imaging provides a new imaging method for measuring uterine hemadynamics.
