CT检查对引起坐骨神经痛病因诊断的价值

The Value of CT Examination in the Diagnosis of the Pathogensis of Sciatia

目的：评价ＣＴ扫描检查对引起坐骨神经痛病因诊断的价值。材料与方法：本组３９例坐骨神经痛患者，结合临床表现，有目的地进行不同部位ＣＴ扫描，在ＣＴ检查出病变的基础上，经手术、病理和随访等手段查明病因。结果：３９例坐骨神经痛患者，ＣＴ检查阳性率１００％，定位诊断准确率１００％，定性诊断符合率７４．４％。结论：ＣＴ扫描具有组织分辩率高与周围组织解剖结构清晰，定位诊断准确、无特殊禁忌症，安全可靠等优点，对引起坐骨神经病病因诊断具有较高的价值，它比普通Ｘ线检查准确度高，比磁共振检查费用低的多。

Purpose:To assess the value of or examination in the diagnosis of the pathogensis of sciatica.Materials and Methods:CT scanning was carried out on a group of thirty-nine patients suffering from sciatica at various sites on the body combined with clinical signs with aim.In this way the etiopathogenisis was determined on the basis of pathologic changes noted by CT scanning and by other methods such as operations,pathologic states and follow-up visits.Results:of all the patients,the positive rate was 100%.The accuracy of the diagnosis of the localization was 100%.Coincidence of the diagnosis of the nature of the lesion was 74.4%.Conclusion:CT scanning has a high value in diagnosis of the pathogenesis of sciatica.It has the following advantages;marked ability to distinguish histologically;clearity in anatomic structure;accuracy in diagnosis of localization of the lesion.no special contraindication;safety and reliability.Compared with the normal X-ray examination.It is more accurate.Compared with MRI the cost is much lower-only 1/4-l/3.It is therefore an ideal from of examination.
