摘　　要：目的探讨时间-空间相关成像技术(spatio-temporal image correlation,STIC)诊断胎儿先天性心脏病(congenital heart disease,CHD)的临床研究价值。方法采用时间空间相关成像技术采集300例孕龄18～40周胎儿,其中正常胎儿210例,胎儿CHD90例的心脏容积图像,并存储分析心脏容积数据。结果 300例胎儿皆成功获得满意的二维和三维四维(3D/4D)四腔心切面的图像。通过STIC技术获得的容积数据显示了一系列相互垂直的三维平面图像即(A平面、B平面、C平面),对其中的每一幅图像都可通过旋转、平移进行控制、分析、切割或三维\四维重建图像,可获得比常规二维胎儿超声心动图检查更多的切面及信息;90例胎儿CHD中146个心脏结构细节异常,二维超声和STIC技术对心脏结构异常的细节总诊断符合率分别为66.44%(97/146)和97.26%(142/146)。结论 3D/4DSTIC技术比常规二维超声心动图检查能更快捷地提供更多的观察心脏解剖结构的切面和信息,且诊断符合率高。Objective To evaluate the diagnostic and clinical value of Multi-slice spiral CT and Reconstruction in Maxillofacial Fracture. Methods 68 cases with maxillofacial fractures were all scaned by GE Lightspeed 16 CT, all the pictures were reconstructed with with multi- planar reformation, and volume render. Results A total 68 cases maxillofacial fractures were showed clearly by Multi-slice spiral CT and Reconstruction,It can clear show the space relationships of facial fragment displacement and tracing fracture lines. Conclusion Multi-slice spiral CT and Reconstruction has important value for diagnosis and clinical in assessing maxillofacial fracture,It can provide space relationship information and panorama of the maxillofacial fracture.
