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 investigate the value of multi-slice spiral CT virtual uterine tubal imaging (MSCT-VHSG) in the examination of tubal patency. Methods: Forty infertility patients underwent intrauterine injection of iodine contrast agent in a total volume of about 20 mL. A 64-slice multislice spiral CT scanner (64 × 0.625 mm 2 detector) 1.0 mm thin layer reconstruction, image workstation was analyzed. Image post-processing techniques include MPR, CPR, MIP and VR. After the patient’s discomfort record. Results: No serious complications occurred during the radiography. The average scan time was (3.4 ± 0.4) s; the mean effective dose was (2.58 ± 0.75) m Sv. MSCT-VHSG acquired uterine and tubal three-dimensional image, clear, causing fewer adverse reactions. 40 cases of tubal tubal in 80 patients showed smooth 40, pass and poor 8, obstruction 32. Conclusion: MSCT-VHSG can be used as a reliable, noninvasive alternative diagnostic technique for infertile patients.
