腰椎横突骨折(lumbar vertebral transverse process fracture,LTF)属于腰椎附件骨折,在腰椎骨折中的发病率仅次于椎体骨折[1]。腰椎横突较薄,呈带状,为由椎弓根与椎弓板会合处向外突出的骨性结构,是腰大肌、腰方肌、棘肌及腰部筋膜的附着点[2]。腰椎横突可直接受损伤或因附着其上肌肉猛烈收缩而发生骨折,以第2及第3腰椎(L2、L3)受伤较多,患者多以腰痛、腰部活动障碍为常见症状。SPECT/CT同机融合显像集合了SPECT的高灵敏度与CT的高特异度的优点,大大提高了LTF诊断的准确率。本研究通过回顾性分析我院LTF患者的SPECT/CT同机融合影像学特征,探讨SPECT/CT同机融合显像在LTF诊断中的应用价值。

摘要:
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。 -

Abstract: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 using χ2 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 (χ2=4.0, P < 0.05). Conclusion SPECT/CT imaging was significantly superior to CT in diagnosis of LTF. -
