文题释义:
MRI检查的不足:在于它扫描所需的时间较长,因而对一些不配合患者的检查常感困难,对运动性器官,例如胃肠道因缺乏合适的对比剂,常显示不清楚;对于肺部,由于呼吸运动以及肺泡内氢质子密度很低等原因,成像效果也不满意。MRI对钙化灶和骨骼病灶的显示,也不如CT准确和敏感。磁共振成像术的空间分辨室,也有待进一步提高。
SPECT-CT检查:是将SPECT和CT进行图像融合,不仅可以进行全身骨显像,一次性获得全身功能代谢信息,又能进行骨断层显像,克服了平面显像对器官、组织重叠造成的掩盖小病灶的缺点;骨折早期即出现血流和成骨细胞活动增加,同时多伴有局部软组织的出血或血肿、炎症反应等,故一般在损伤后6-72 h内可见到放射性浓聚区(即有阳性发现),能显示局部异常活跃的骨代谢活动,其灵敏度较高,特异性欠缺。
 
摘要
背景:骨质疏松性椎体压缩性骨折的诊断已有较多研究,然而目前对不同时期骨折诊断方法的研究较少。
目的:比较分析高强度MRI与SPECT-CT在诊断骨质疏松性椎体压缩骨折中的应用价值。
方法:回顾性分析35例骨质疏松性椎体压缩骨折患者的临床资料,涉及责任椎体56个,其中男14例,女21例,平均年龄72.6岁。其中22例病程在3周内,属于急性期骨折;10例病程在4-12周内,属于亚急性骨折;3例病程在6个月以上,属于骨折愈合期。所有患者同时接受高强度MRI及SPECT-CT检查,并行经皮椎体成形或经皮椎体后凸成形治疗,使用Fisher精确检验方法比较两种诊断方法对椎体骨折的显示情况。
结果与结论:①在56个责任椎体中:32个椎体属于急性期骨折,24个椎体属于非急性期骨折。在所有骨折椎体中,MRI诊断49个节段,SPECT-CT诊断52个节段,SPECT-CT检查的敏感度高于MRI检查,特异度低于MRI检查,两者诊断骨折有较高的一致性;②32个急性期椎体骨折中:两种检查各诊断29个节段,SPECT-CT检查的敏感度高于MRI检查,特异度低于MRI检查,两者诊断骨折有较高的一致性;③24个非急性椎体骨折中:MRI诊断20个节段;SPECT-CT诊断23个节段,SPECT-CT检查的敏感度高于MRI检查,特异度低于MRI检查,两者诊断骨折有较高的一致性;④MRI与SPECT-CT检查对不同时期骨折责任椎体的确定具有很高的一致性,但SPECT-CT检查较MRI检查的敏感性更高,是诊断椎体骨折的一种有效检查方法。

Abstract:

BACKGROUND: There have been many studies on the diagnosis of osteoporotic vertebral compression fractures. However, there are few studies on the diagnostic methods of fracture in different periods.

OBJECTIVE: To comparatively analyze the application value of high-intensity magnetic resonance imaging (MRI) and single photon emission computed tomography combined with CT scan image fusion (SPECT-CT) in the diagnosis of osteoporotic vertebral compression fractures.
METHODS: Clinical data of 35 patients with osteoporotic vertebral compression fractures were retrospectively analyzed, including 56 vertebrae. There were 14 males and 21 females, with an average age of 72.6 years. The course of disease was within 3 weeks in 22 patients, belonging to acute fractures. The course of the disease was between 4 and 12 weeks in 10 patients, belonging to the subacute fractures. The course of disease was 6 months in 3 patients, belonging to the fracture healing period. All patients were tested with high-intensity MRI and SPECT-CT examination, and were treated with vertebroplasty or percutaneous kyphoplasty. The Fisher exact method was used to compare the two diagnostic methods in the diagnosis of vertebral fracture.
RESULTS AND CONCLUSION: (1) In the 56 responsible vertebral bodies, 32 vertebral bodies belonged to the acute-stage fractures, and 24 vertebral bodies belonged to the non-acute-stage fractures. In all the fractures, MRI diagnosed 49 segments; SPECT-CT diagnosed 52 segments. The sensitivity of SPECT-CT testing was higher than MRI, and its specificity was less than MRI. There was a high consistency of diagnosis between fractures. (2) In the 32 acute vertebral fractures, the two tests diagnosed 29 segments. The sensitivity of SPECT-CT was higher than that of MRI, but its specificity was lower than that of the MRI. There was a high consistency between the diagnoses of fractures. (3) In the 24 non-acute vertebral fractures, MRI diagnosed 20 segments; SPECT-CT diagnosed 23 segments. SPECT-CT was more sensitive than MRI; the specificity of SPECT-CT was lower than MRI. There was a high consistency between the two diagnoses of fractures. (4) There was a high consistency in the MRI and SPECT-CT examination to determine the fracture of different periods of responsibility of the vertebral body, but the sensitivity of SPECT-CT is higher than MRI examination; SPECT-CT is an effective inspection method in the diagnosis of vertebral fractures.
