摘要
目的:探讨多层螺旋CT(MSCT)的螺旋扫描及轴层扫描方法在腰椎病变中的应用。方法:对126例临床上有腰腿痛症状的患者行腰椎螺旋CT扫描,其中28例加做轴层扫描,然后对螺旋扫描的数据进行后处理,将重组图像与轴层扫描的图像进行比较,分析图像的质量。结果:MSCT扫描后重组的横轴面图像与直接轴层扫描的图像相比无明显差别,完全符合诊断质量,提供的信息更丰富。结论:利用MSCT的螺旋扫描方法及重组技术,不仅能对椎间盘病变进行诊断,还能发现常规轴层扫描所遗漏的疾病,显著提高腰椎病变的检出率,使患者更容易固定,扫描架亦毋需倾斜,不受腰椎间隙角度的限制。
Objective： To compare the application of volume scanning and non-volume scanning with multi-slice CT （MSCT） in lumbar spine diseases. Methods： Volume scanning with MSCT was performed in 126 patients with clinical symptoms. Among them additional non volume scanning was carried out in 28 patients. Comparative analysis between the volume scanning and the non volume scanning was made after the volume data were post-processed. Results： No remarkable differences were found between the reconstructed image and the directly collected image, which conformed to the diagnostic standard with ample image information, the disease could be accurately diagnosed. Conclusion： With the application o~ volume scanning and post processing technique, not only the disease in inter vertebral disc could be diagnosed, but also some disease neglected in non volume scanning could be discovered. Using this technique the diagnosis rate would be significantly improved,and the patient could take a more comfortable examination gesture.
