评价骶骨CT冠状位扫描临床应用价值

The Value of Coronal CT Scan of Sacrum and Sacroiliac Joint

目的:比较CT冠状位扫描和横断位扫描对骶骨与骶髂关节的解剖结构和影像特征的显示,探讨CT冠状位扫描应用价值。方法:分别对随机分组的骶骨与骶髂关节病变采用轴位加重建45例,冠状位45例进行扫描,对比其对诊断的优越性。结果:冠状位扫描图像质量及诊断准确率优于轴位扫描。结论:CT冠状位扫描对骶骨与骶髂关节影像结构的显示明显优于横断位扫描,更能显示其细微的影像学特征。

Objective To study the efficacy ofcoronal CT scan in the diagnosis and differential diagnosis of lesions withsacrum and sacroiliac joint.comparing the anatomic structures and imaging features of sacrum and sacroiliac joint.on coronal sacrum and sacroiliac joint CT scan with those on axial.Methods In the contrast study, CT axial scanning plus reconstruction was performed in 45 randomized cases and so was coronal scanning in 45 randomized cases of sacrum and sacroiliac joint.Results The image quality and diagnostic accuracy of CT coronal scan proved superior to those of CT axial scan.Conclusion Coronal CT scan of sacrum and sacroiliac jointis obviously superior to axial scan in depicting the structure , especially in tiny features of sacrum and sacroiliac joint.
