摘要
目的:探讨256层CTA在椎-基底动脉病变中的应用及诊断价值。方法:对150例行256层CTA检查的受检者图像进行回顾性分析,结合MPR、CPR、MIP、SVR观察椎动脉形态学变化及其与邻近骨结构的关系,准确测量狭窄段长度。结果:150例受检者中先天发育变异30例,占20.0%;粥样硬化斑块40例,占26.7%;钩椎关节增生压迫并走行迂曲18例,占12.0%;动脉瘤4例,占2.67%。结论:256层CTA能清晰显示椎-基底动脉解剖结构,对椎-基底动脉病变准确诊断、分型、及其治疗方案的制定和预后判断具有重要价值,是椎基底动脉病变的重要检查方法。
Objective：To investigate the diagnostic value of 256-slice CTangiography （MSCTA） in vertebro-basilar artcri- al lesions. Methods： 150 patients underwent MSCTA with bolus trigger technique. The row data were transferred to EBW4.5.2 workstation to make 3D image processing. Advanced vessel analysis （AVA） were used to reconstruct bilateral vertebral arteries with transverse axial planar reconstruction, shaded volume rendering （SVR）, multiplanar reconstruction （MPR）, maximun intensity projection （MIP） and curved planar reconstruction （CPR）. Morphological changes of the ver- tebral arteries and the influence arising from surrounding bony structure were analyzed by AVA. Results=In 150 cases, 30 cases presented with developmental anomaly （20.0%）, 40 cases with atheromatous plaque （26.7%）, 18 cases were op- pressed by osseous hypertrophy of cervical Luschka＇ s joints with coiling （12 %） and 4 cases with aneurysm （2. 67 % ）. Conclusion：256 MSCTA can display clearly changes of vertebro-basilar artery and its neighboring bone structures. And with AVA, it has important clinical value for etiologic study, typing and therapeutic planning of vertebro-basilar arterial lesions.
