MRI与CT诊断隐匿性骨折患者临床检出率研究

摘要/Abstract

摘要： 目的研究并比较磁共振成像（MRI）与电子计算机断层扫描（CT）对隐匿性骨折的诊断价值。方法分析2017年5月~2020年5月在哈尔滨市第二医院拟诊为四肢骨关节隐匿性骨折患者92例的临床资料,均分别行MRI、CT诊断,手术或关节镜确诊结果作为金标准,比较临床诊断资料。结果 92例拟诊为隐匿性骨折患者,手术或关节镜确诊76例（82.61%）;MRI对四肢各部位隐匿性骨折的检出率较CT检出率高（P<0.05）;MRI检查对双边征、骨质破坏、充气征及软组织影的检出率均显著高于CT（P<0.05）。结论 MRI与CT诊断隐匿性骨折时,MRI的临床检出率更好,可清晰显示出骨折影像学特征。

Abstract: Objective To study and compare the diagnostic value of magnetic resonance imaging (MRI) and computed tomography (CT) in occult fracture. Methods The clinical data of 92 patients with occult fractures of bones and joints of limbs in the Second Hospital of Harbin from May 2017 to May 2020 was analyzed. MRI and CT diagnosis were performed respectively, and the results of surgery or arthroscopy were taken as the gold standard, and the clinical diagnosis data were compared. Results Ninety-two patients were suspected to have occult fracture, 76 patients (82.61%) were diagnosed by surgery or arthroscopy; The detection rate of occult fractures in all parts of limbs by MRI was higher than that by CT (P<0.05); The detection rate of bilateral sign, bone destruction, inflatable sign and soft tissue image on MRI was significantly higher than that on CT (P<0.05). Conclusion When MRI and CT diagnose occult fracture, MRI has better clinical detection rate and can clearly show the imaging features of fracture.

Key words: magnetic resonance imaging, computed tomography, occult fracture
