子宫及子宫肌瘤多层螺旋CT灌注成像的初步研究

The Multislice CT Perfusion Imaging in Uterus and Uterine Leiomyoma

  • 摘要: 目的:探讨子宫多层螺旋CT灌注成像的方法及其在评价子宫肌瘤血流灌注状态中的应用。方法:对17例受检者先行盆腔常规平扫,然后对选定层面采用MultiScan序列进行多层螺旋CT灌注扫描,应用Perfusion CT软件包对灌注图像进行后处理,测量并记录子宫肌瘤(n=18)及正常子宫肌层(n=17)的血流量、血容量及达峰时间。结果:所有病例子宫多层螺旋CT灌注成像均获得成功;灌注成像显示子宫肌瘤灌注高于正常子宫肌层(t=3.540,P=0.001),子宫肌瘤的血流量、血容量及达峰时间分别为(54.87±19.09)ml.100g-1.min-1、(12.41±4.07)%和(18.61±5.31)s。正常子宫肌层的血流量、血容量及达峰时间分别为(32.82±17.68)ml.100g-1.min-1、(8.78±6.25)%和(20.64±5.71)s。结论:多层螺旋CT灌注成像为定量检测子宫及子宫肌瘤血流灌注状态提供了一种新的影像学方法。

     

    Abstract: Objective: The purpose of this study was to explore the application of multislice CT perfusion imaging in uterus and uterine leiomyoma.Methods: Routine pelvic CT was performed in 17 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 leiomyoma and the normal uterine tissue(around the tumor) were measured and documented respectively.Results: All cases of multislice perfusion imaging were successfully performed.A significant difference in Blood Flow between uterine leiomyoma and the normal uterine tissue(around the tumor) was showed.The Blood Flow,Blood Volume and Time To Peak of the uterine leiomyoma were(54.87±19.09)ml.100g-1.min-1,(12.41±4.07)% and(18.61±5.31)s.The Blood Flow,Blood Volume and Time To Peak of the normal uterine tissue(around the tumor) were(32.82±17.68)ml.100g-1.min-1,(8.78±6.25)% and(20.64±5.71)s.Conclusion: Multislice CT perfusion imaging provided a new imaging method for measuring the uterine hemadynamic.
