摘　　要：目的:探讨磁共振成像(MRI)检查在非典型慢性化脓性骨髓炎(CPO)患者诊断中的临床应用价值。方法:选取医院接诊的83例骨感染和骨肿瘤患者影像资料,将采用CT影像检查的患者纳入对照组,磁共振影像检查的患者纳入观察组,由两位放射科医师对两组影像进行盲法诊断。结果:两组的CPO、骨样骨瘤及骨肿瘤诊断准确率差异无统计学意义;观察组的非典型病例诊断准确率为96.5%,高于对照组(75.9%),其差异具有统计学意义(x2=5.220,P<0.05)。结论:对比于CT检查,MRI检查可以有效地提高非典型CPO的诊断准确率,在与骨样骨瘤、骨肉瘤的鉴别诊断方面具有重要的应用价值。Objective:To explore the clinical application value of magnetic resonance imaging(MRI)in diagnosing atypical chronic pyogenic osteomyelitis(CPO)of patients.Methods:The imaging data of 83 patients with bone infection and bone tumor,who received diagnosis and treatment in hospital,were selected.Patients who underwent CT imaging examination were divided in control group,and those who underwent MRI imaging examination were divided in observation group.And the images data of two groups were diagnosed by two radiologists as blind method.Results:There were no significant differences in the diagnostic accuracies of CPO,osteoidosteoma and bone tumor between the two groups.And the diagnostic accuracy of atypical cases of observation group was 96.5%,which was significantly higher than that(75.9%)of control group(x2=5.220,P<0.05).Conclusions:Compared with CT examination,MRI examination can effectively improve the diagnostic accuracy of atypical CPO,and it has important application value on the aspect of differential diagnosis for osteoidosteoma and osteosarcoma.
