[摘要] 目的 探討椎管內占位性病變診斷中MRI影像的應用效果。 方法 整群選擇該院2012年7月—2016年4月收治的經手術及病理證實的椎管內占位性病變患者66例,均在術前先后給予CT及MRI檢查,觀察CT及MRI檢查準確率,并分析MRI表現。 結果 MRI檢查準確率為100.0%,CT檢查準確率為84.8%,MRI檢查準確率高于CT檢查,差異具有統計學意義(P<0.05)。觀察MRI影像可知,椎管內占位多為良性腫瘤,T1上多為低或等信號,T2上多為高信號。結論 椎管內占位診斷中,MRI影響檢出率較高,應在臨床中進一步應用。

[Abstract] Objective To observe the spinal canal and application effect of MRI imaging diagnosis of space-occupying lesions. Methods Group selection selected in July 2012 to April 2016 were confirmed by surgery and pathology in 66 cases of patients with space-occupying lesion of intra-spinal canal, in preoperative successively for CT and MRI examination, observation of CT and MRI examination accuracy, and analyze the MRI manifestations. Results MRI accuracy rate is 100.0%, CT examination accuracy is 84.8%,MRI accuracy higher than that of CT examination, statistically significant difference (P < 0.05). To observe MRI images, the spinal canal placeholder for benign tumors, much for low or equal signal on T1, T2 on high signal. Conclusion The spinal canal placeholder diagnosis, MRI affect the detection rate is higher, should further application in clinical.

椎管內占位性病變屬于腫瘤病變,脊髓、脊膜、神經根、椎管內其他組織為腫瘤的原發部位,病變具有占位效應。臨床診斷椎管內占位性病變時,可采用的檢查手段比較多,比如CT檢查、MRI檢查等,但各種檢查手段的準確性存在一定差異,該研究以2012年7月—2016年4月收治椎管內占位患者66例為研究對象,分析了椎管內占位性病變診斷中MRI影像的應用價值,現報道如下。
