| 摘 要： | 目的探讨螺旋CT三维重建技术在骨肿瘤病变中的应用价值。方法选择20例骨肿瘤螺旋CT三维重建图像,扫描层厚2～3mm,重建间隔1.5mm,螺距为1,数据输入工作站,用SSD及MPR重建方法进行处理。结果20例骨肿瘤三维CT重建图像显示良好。骨肿瘤的整体形态及与周围解剖结构的关系得到较好的观察。结论我们认为SSD及MPR重建方法的结合运用,并参考CT的横断图像进行综合分析将提高螺旋CT对骨肿瘤的定性和实用价值。

| Abstract: | Objective To evaluate the clinical application of 3D CT reconstruction technique in bone tumor. Methods In total 20 cases with bone tumor were scanned in 2- 3mm collimation and at pitch of 1 using Toshiba Xpress/SX CT scanner. After the scan was completed, 3D reconstruction including SSD and MPR was performed at Sun Sparc station 20 workstation with software Toshiba Xtension 2.01. Results Quality 3D images were obtained in all 20 cases. The stereoscopy of the tumor and surrounding anatomical structure was well demonstrated in 3D images. Conclusion Besides axial images, the 3D CT reconstruction including SSD and MPR provides extra informations, and helps the qualitative diagnosis of bone tumor. |
