磁共振脂肪抑制STIR序列在椎体压缩性骨折中的诊断价值研究

Diagnostic Value of Magnetic Resonance Fat Suppression STIR Sequence in Vertebral Compression Fractures

目的探讨磁共振脂肪抑制STIR序列在椎体压缩性骨折诊断中的临床价值。方法收集我院2015年3月-2016年4月我院收治的经手术或临床病理证实为椎体压缩性骨折患者42例的影像学资料。所有研究者均行常规磁共振及磁共振脂肪抑制STIR序列检查,并阐述磁共振脂肪抑制STIR序列对椎体压缩性骨折中的临床诊断价值。结果 42例研究对象中,其中24例骨折部位为胸椎,18例骨折部位为腰椎,其中为单个椎体病变的有28例,为多节椎体病变的有14例;椎体压缩性骨折在MRI图像上主要呈现凹陷形和扁平形;其中椎体后缘骨皮质主要表现形态为:骨皮质后缘上、下角后翘,后缘皮质成角;在T1WI扫描序列中椎体内呈低信号显示,在T2WI扫描序列上椎体内呈稍高信号,在脂肪抑制STIR序列上椎体内显示大部分为高信号,少数椎体内出现小部分低信号;磁共振脂肪抑制STIR序列对42例患者的检查结果均显示为椎体压缩性骨折,磁共振脂肪抑制STIR序列对椎体压缩性骨折的确诊率为100%。磁共振脂肪抑制STIR序列扫描对椎体压缩性骨折的形态、附件及周围软组织显影均直观清晰。结论磁共振脂肪抑制STIR序列对椎体压缩性骨折检出率高,能从多角度、多切面准确显示椎体压缩骨折的具体情况,为临床提供了影像学资料具有重要指导作用。

Objective To investigate the clinical value of magnetic resonance fat suppression STIR sequence in the diagnosis of vertebral compression fractures. Methods The imaging data of 42 patients with vertebral compression fractures confirmed by surgery or clinical pathology in our hospital from March 2015 to April 2016 were collected. All participants underwent conventional MRI and STIR fat suppression sequence checking, and described the MRI fat suppression sequence of STIR vertebral compression fractures in clinical diagnosis. Results 42 cases were studied, including 24 cases of thoracic fracture, 18 cases of fracture site of lumbar spine, including single vertebral body lesions in 28 cases, a plurality of vertebral body lesions in 14 cases. V_ertebral compression fractures on the MRI image shows the main concave and flat shape, the posterior cortical bone vertebral main forms： posterior cortical bone of upper and lower corner after Alice, posterior cortex angle; In the T1 WI scan sequence, the vertebral body showed a low signal, and a slightly higher signal appeared in the vertebral body on the T2 WI scan sequence. In the fat suppressed STIR sequence, most of the vertebral body showed high signal, and a few small signals appeared in the vertebral body. Magnetic resonance fat suppression STIR sequence of 42 patients showed vertebral compression fractures, magnetic resonance fat suppression STIR sequence of vertebral compression fracture diagnosis rate was 100%. Magnetic resonance fat suppression STIR sequence scan of vertebral compression fracture shape, accessories and surrounding soft tissue development is intuitive and clear. Conclusion Magnetic resonance fat suppression STIR sequence has high detection rate of vertebral compression fracture, and can display the specific situation of vertebral compression fracture from multi angle and multi view, which provides important imaging data for clinical guidance.
