| 【摘要】目的：探讨多层螺旋CT（MSCT）后重组技术显示椎动脉型颈椎病（CSA）病因的应用价值。方法：对128例临床诊断为CSA的患者进行MSCT检查，将原始数据进行高级血管分析（AVA）、容积再现（VR）、最大密度投影（MIP）等后处理技术重组并结合原始图像进行分析。采用卡方检验评价上述3种后处理方法对CSA病因的显示率。结果：128例CSA患者重组结果及统计学分析显示，AVA与VR对钩椎关节增生的显示率，AVA分别与VR、MIP对椎动脉（VA）钙化的显示率， AVA与MIP对VA狭窄的显示率间差异均有统计学意义（P<0.05）。结论：MSCT可作为无创性诊断CSA的一种简便、优良的影像学检查方法。各种后处理方法显示病因均有其优势，AVA能提高病因的显示率，最终诊断需结合原始图像进行综合分析。 |
| 【Abstract】Objective：To explore the application value of multislice spiral CT （MSCT) angiography in diagnosis of cervical spondylosis of vertebral artery type （CSA）.Methods：Enhanced 64-MDCT scanning was performed in 128 clinically diagnosed patients with CSA．Images were post-processed by using volume rendering (VR)，maximum intensity projection (MIP) and advanced vessel analysis (AVA).The display rate of pathological changes of CSA was compared with χ2 test.Results：AVA,MIP and VR were performed in 128 patients.The differences of display rate were statistically significant between AVA and VR in proliferation of Luschka joint (P<0.05).In demonstration of vertebral artery calcification,there was statistical significant difference between AVA and VR,and between AVA and MIP (P<0.05).In demonstration of vertebral artery stenosis,there was statistical significant difference between AVA and MIP (P<0.05).Conclusion：MDCT is an effective，noninvasive and simple imaging technique with high image quality．Every kind of post-processing method has its advantages.AVA can improve the display rate of pathological changes of CSA，but the final diagnosis needs to combine with the original image. |
