【摘要】：目的对螺旋CT和MRI在隐性骨折早期诊断中的价值进行探讨分析。方法将210例可疑隐性骨折患者作为本次研究的对象,行螺旋CT和MRI检测,比较两种检测准确度。结果本组患者经确诊,有50例患者为疲劳骨折,34例患者为衰竭骨折,76例为隐性骨内骨折,另外50例为隐性创伤骨折。在疲劳骨折患者及隐性骨内骨折患者的早期诊断中,MRI诊断确性显著高于螺旋CT(P0.05);在衰竭骨折患者及隐性创伤骨折患者的早期诊断中,螺旋CT则可以获得更高的诊断准确率(P0.05)。就敏感度而言,螺旋CT对疲劳骨折、隐性骨内骨折、隐性创伤骨折早期诊断方面显著优于MRI(P0.05),而MRI对衰竭骨折早期诊断的特异度高于螺旋CT,螺旋CT对隐性骨内骨折的特异度高于MRI(P0.05)。结论螺旋CT和MRI是两种非常有效的隐性骨折早期诊断方式,且两种方式在不同类型的隐性骨折诊断中各具优势,均具有非常重要的临床价值,临床在诊断过程中应根据实际情况采取相应的检测方式,以提高病情诊断准确率。
[Abstract]:Objective to investigate the value of spiral CT and MRI in the early diagnosis of occult fracture. Methods 210 patients with suspected occult fracture were examined by spiral CT and MRI, and the accuracy of the two methods was compared. Results there were 50 cases of fatigue fracture, 34 cases of failure fracture, 76 cases of recessive intraosseous fracture and 50 cases of recessive traumatic fracture. In the early diagnosis of fatigue fracture and recessive intraosseous fracture, the diagnostic accuracy of MRI was significantly higher than that of spiral CT (P0.05). In the early diagnosis of failure fracture and recessive trauma fracture, spiral CT can obtain higher diagnostic accuracy (P0.05). In terms of sensitivity, spiral CT was significantly superior to MRI in early diagnosis of fatigue fracture, recessive intraosseous fracture and recessive traumatic fracture (P0.05), while MRI was more specific in early diagnosis of failure fracture than spiral CT,. The specificity of spiral CT in the treatment of occult intraosseous fracture was higher than that of MRI (P0.05). Conclusion Spiral CT and MRI are two effective methods for early diagnosis of occult fractures, and the two methods have their own advantages in the diagnosis of different types of occult fractures, and both have very important clinical value. In order to improve the accuracy of the diagnosis, we should adopt the corresponding detection method according to the actual situation in the clinical diagnosis process.
