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.
