螺旋CT多平面重建技术在腰椎峡部裂诊断中的价值

目的探讨螺旋CT多平面重建(MPR)技术在诊断腰椎峡部裂中的临床应用价值。方法搜集腰椎SCT容积扫描,经后处理重建检出的腰椎峡部裂42例,分析其MPR成像的CT表现,评价对峡部裂及其继发病变的显示情况。结果MPR额状面、经椎弓矢状面重建成像清晰显示42例79处峡部裂;常规椎弓CT轴位像仅检出28例58处峡部裂,漏诊14例,漏诊率33.3%(14/42)。结论SCT容积扫描,MPR重建对峡部裂及其相关继发病变具有良好的显示能力,是检出峡部裂及其继发病变的较理想成像方法。

The Diagnostic Value of Spiral CT MPR in Lumber Spondyloschisis

Objective To evaluate the clinical application value of spiral CT (SCT) MPR technique in lumber spondyloschisis diagnosis. Methods To select 42 lumber spondyloschisis cases which confirmed by CT post-processing, compare its MPR image with routine CT axial image of arcus vertebrae, evaluate their display ability of spondyloschisis. Results Coronary and sagittal image of MPR combined could clearly display 79 spondylolysis in 42 cases. The routine axial CT image could only display 58 spondylolysis in 28 cases and failed to diagnose 14 cases, the rate is 33.3% (14/42). Conclusion SCT MPR techniques have good display ability in spondyloschisis and its secondary abnormity, it is an ideal method in spondyloschisis diagnosis.
