摘　　要：目的分析和对比CT与MRI在四肢骨关节隐匿性骨折诊断中的应用价值。方法简单随机选取2022年1—12月山东省菏泽市单县东大医院收治的60例疑似四肢骨关节隐匿性骨折患者作为研究对象,入院后,分别对其行CT、MRI检查,以手术检查结果为金标准,对比两种诊断技术对四肢骨关节隐匿性骨折诊断的准确度、灵敏度、特异度及诊断符合率。结果金标准诊断出阳性57例,阴性3例;CT诊断出阳性51例,阴性9例;MRI诊断出阳性56例,阴性4例。MRI诊断准确度(98.33%)、灵敏度(98.25%)、特异度(100.00%),高于CT的86.67%、87.72%、66.67%,差异有统计学意义(χ^(2)=9.219、9.327、9.348,P均<0.05);MRI诊断符合率高于CT,差异有统计学意义(P<0.05)。结论在四肢骨关节隐匿性骨折的诊断中,CT和MRI都具有一定的应用价值。相较于CT,MRI的三维重建技术能够提供更准确的诊断结果,且诊断灵敏度和特异度较高。Objective To analyze and compare CT and MRI in the diagnosis of occult fractures of limb bones and joints.Methods Sixty patients with suspected occulted bone and joint fractures of limbs admitted to Dongda Hospital of Shanxian,Heze City,Shandong Province from January to December 2022 were simply and randomly selected as the study objects.CT and MRI were performed on them after admission,and surgical examination results were used as the gold standard.The accuracy,sensitivity,specificity and diagnostic coincidence rate of the two diagnostic techniques were compared in the diagnosis of occult fracture of limbs and joints.Results Gold standard diagnosis was positive in 57 cases,negative in 3 cases;CT diagnosis was positive in 51 cases,negative in 9 cases;MRI diagnosis was positive in 56 cases,negative in 4 cases.The diagnostic accuracy(98.33%),sensitivity(98.25%)and specificity(100.00%)of MRI were higher than those of CT(86.67%,87.72%and 66.67%),and the differences were statistically significant(χ^(2)=9.219,9.327,9.348,all P<0.05).The coincidence rate of MRI diagnosis was higher than that of CT diagnosis,the difference was statistically significant(P<0.05).Conclusion Both CT and MRI have certain application value in the diagnosis of occult fractures of limb bones and joints.Compared with CT,three-dimensional reconstruction of MRI can provide more accurate diagnostic results,with higher diagnostic sensitivity and specificity.
