SPECT/CT融合显像在腰椎横突骨折诊断中的应用价值

目的探讨SPECT/CT同机融合显像在腰椎横突骨折（LTF）诊断中的应用价值。方法收集2013年6月至2015年6月腰部不适并经X射线检查排除腰椎退变及转移的患者共203例，根据病理结果及6个月以上随访结果，最终42例患者共49个病灶确诊为LTF，阳性病灶均行SPECT/CT同机融合显像，对病灶进行CT及SPECT/CT阅片。病灶检出率比较采用χ2检验。结果 SPECT/CT同机融合显像发现LTF病灶共45个，其中，第1至第5腰椎（L1-L5）分别为4、12、21、8、0个，以L2（26%）和L3（46%）发病率较高。CT扫描发现LTF病灶共38个。两种方法对LTF的检出率差异具有统计学意义（χ2=4.0，P < 0.05）。结论 SPECT/CT同机融合显像在诊断LTF方面具有良好的临床应用价值。

Application value analysis on SPECT/CT in the diagnosis of lumbar vertebral transverse process fracture

Objective To investigate the diagnostic value of SPECT/CT on lumbar vertebral transverse process fracture (LTF).Methods From June 2013 to June 2015,203 patients with flank pain were collected by X-ray eliminating lumbar vertebral degeneration or bone metastasis.A total of 42 patients with 49 LTF lesions confirmed by pathology or follow-up over six months of imaging underwent both SPECT/CT and CT examinations.Imaging findings in all patients were analyzed independently.The prevalence of lesion was statistically analyzed usingx2 test.Results SPECT/CT was able to detect 45 lesions,wherein 4,12,21,8,0 lesions were observed from L1 (the first lumbar) to L5 (the fifth lumbar),respectively.Meanwhile,the CT images showed 38 lesions.Significant differences were observed between SPECT/CT and CT (x2 =4.0,P ＜ 0.05).Conclusion SPECT/CT imaging was significantly superior to CT in diagnosis of LTF.
