目的：探讨应力性骨折的影像学表现，以提高对该病的早期诊断、早期治疗。
方法：回顾性分析336例应力性骨折患者的DR、CT、MRI影像学资料，采用卡方检验对比分析3种检查方法对应力性骨折早期诊断率。
结果：DR、CT、MRI检查的早期诊断率分别为70.83%（238/332）、55.93%（66/118）、73.61%（53/72），三者比较差异有统计学意义（χ2=10.15 P=0.006），DR检查早期诊断率高于CT （χ2=8.765 P=0.003），DR检查与MR比较差异无统计学意义（χ2=0.224 P=0.636）。
结论：DR和MRI对应力性骨折均有较好诊断能力，CT检查对应力性骨折的早期诊断帮助不大，DR检查经济、方便，是应力性骨折的首选检查方法，MR是应力性骨折的首选补充检查手段，可提高应力性骨折的早期诊断，为临床提供影像学诊断依据，使应力性骨折得到早期干预和治疗。 |

Abstract:
Objective: To discuss the imaging findings of stress fracture,in order to improve the ability of early diagnosis and early treatment of this disease.
Methods: The DR,CT and MRI imaging data of 336 cases of stress fracture from January 2010 to January 2016 were analyzed retrospectively. Early diagnosis ratio in stress fractures by three methods were analyzed using χ2-test.
Results: Early diagnosis ratio of three methods as follow:DR was 70.83%(238/332),CT was 55.93%(66/118),and MRI was 73.61%(53/72). There was statistical significance among three methods (χ2=10.15,P=0.006),the early diagnosis ratio of DR was higher than CT (χ2=8.765,P=0.003)and there was no statistical significance between DR and MRI (χ2=0.224,P=0.636).
Conclusion: DR and MRI have better diagnosis of stress fractures while CT is not helpful in the early diagnosis. DR examination is preferred method due to its economical and convenient. MR is the important complement means,which can improve the early diagnosis ratio and provide imaging diagnosis basis for the clinical,so that the disease get early intervention and treatment. |
