摘　　要：目的:探讨多层螺旋CT虚拟子宫输卵管造影(MSCT-VHSG)在检查输卵管通畅性方面的应用价值。方法:对40例不孕症患者,宫腔内注入总量约20 m L稀释碘对比剂后,进行64排多层螺旋CT扫描仪(64×0.625 mm2探测器)扫描,回顾性0.6 mm到1.0 mm薄层重建,图像工作站进行了分析。图像后处理技术包括MPR、CPR、MIP及VR等。术后对患者的不适情况进行记录。结果:在造影过程中没有发生严重并发症。平均扫描时间为(3.4±0.4)s;患者的平均有效剂量为(2.58±0.75)m Sv。MSCT-VHSG获得的子宫宫腔及输卵管图像立体、清晰,引起的不良反应少。40例患者80条输卵管中显示输卵管通畅40条,通而不畅8条,阻塞32条。结论:MSCT-VHSG可作为不育症患者的一个可靠的、非侵入性的替代诊断技术加以应用。Objective： To explore the clinic value of Multi-slice spiral CT-virtual hysterosalpingography in diagnosing fallopain tube patency. Methods： The pelvic cavity MSCT was performed on 40 infertility patients, MSCT-VHSG was performed with a 64-row CT scanner using 64 × 0.625 mm2 collimation and 0.625 mm slice thickness. A total volume of 20 mL of an iodine contrast dilution was injected into the uterine cavity. The duraion of the CT scan and the grade of patient discomfort of the procedure were documented. Images were analyzed on a workstation. Retrospective thin-slice reconstruction 0.625 mm to 1.5 mm after multi-slice spiral CT scan, the techniques such as MPR, CPR, VR and MIP, were used to observe fallopain tube patency. Results： No complications occurred during the procedure, The mean scan time was （3.4 ± 0.4）s; the mean patient effective dose was （2.58 ± 0.75）mSv. The stereo pictures of the uterus cave were obtained on MSCT-VHSG. The fallopian tube was clearly visualized without obvious adverse reactions occurring. Forty fallopian tube were diagnosed as patent,8 as partially patent and 32 as non-patent by MSCT-VHSG. Conclusion： A 64-row CT-VHSG provides a reliable, non-invasive alternative diagnostic technique in the infertility workup algorithm.
