摘要
对40例脊柱病变,做了CT 三维重建成像,并与横断面CT 及二维重建CT 像进行了比较,以评估三维重建CT 在脊柱病变中的应用价值。作者认为,三维CT 的主要优点是它能在显示碎骨片移位的同时,准确地显示椎间孔的情况。主要缺点是降低了空间与密度分辨率,且对软组织显示无意义。对那些横断面CT 已显示有碎骨片移位或疑有椎间孔狭窄的病例,三维CT 为一种有益的补充检查方法。
The images produced by three-dimentional CT(3-D CT)reconstruction technique in40 patients with spinal disorders were compared with that of their cross-section and two-dimentional CT(2-D CT)reconstruction to evaluate the value of(3-D CT)in the diagnosis of spinal diseases.Theprincipal advantage of 3-D CT was that it precisely delineating the change of intervertebral foramenswhile demonstrating the displacemennt of fractured osseous fragments.The main disadvantage of thismethod was the significantly decreasin...
