摘　　要：目的:探究磁共振弥散张量成像(DTI)技术在布氏杆菌脊柱炎(BS)中的诊断效能及相关参数。方法:选择2020年8月—2022年7月于新疆医科大学附属中医医院就诊的疑似BS的40例患者作为研究对象,均行CT及磁共振DTI技术检查。将实验室检测及细菌学培养结果作为“金标准”,分析CT及磁共振DTI技术在BS中的诊断价值;对BS患者进行随访,对比治疗前及治疗后的各向异性分数(FA)值及表观弥散系数(ADC)值。结果:磁共振DTI在BS诊断中准确率高于CT检查,差异有统计学意义(P<0.05);两者灵敏度、特异度、阳性预测值及阴性预测值对比,差异无统计学意义(P>0.05)。治疗后急性期与亚急性期的ADC值及FA值均小于治疗前,而慢性期治疗后ADC值小于治疗前,FA值大于治疗前,差异有统计学意义(P<0.05)。结论:磁共振DTI技术在BS诊断中准确率较高,可依据ADC及FA值变化判断患者疾病时期,同时对指导临床治疗具有重要作用,值得推广应用。Objective To explore the diagnostic efficacy and related parameters of magnetic resonance diffusion tensor imaging(DTI)technology in Brucella spondylitis(BS).Methods 40 patients with suspected BS who were treated in the Affiliated Hospital of Traditional Chinese Medicine of Xinjiang Medical University from August 2020 to July 2022 were selected as the study objects,and all of them were examined by CT and magnetic resonance DTI techniques.The results of laboratory test and bacteriological culture were taken as the"gold standard"to analyze the diagnostic value of CT and magnetic resonance DTI in BS.Patients with BS were followed up to compare the anisotropy fraction(FA)and apparent diffusion coefficient(ADC)values before and after treatment.Results The accuracy of MRI DTI in the diagnosis of BS was higher than that of CT(P<0.05).There were no significant differences in sensitivity,specificity,positive and negative predictive values between the two groups(P>0.05).After treatment,ADC and FA values in acute and subacute stages were lower than those of before treatment,while ADC values in chronic stage were lower than that of before treatment,and FA values were higher than that of before treatment,with statistical differences(P<0.05).Conclusion Magnetic resonance DTI technology has high accuracy in the diagnosis of BS,and can determine the disease stage of patients based on changes in ADC and FA values.It also plays an important role in guiding clinical treatment and is worth promoting and applying.
