Abstract: Objective To assess the diagnostic value of apparent diffusion coefficient (ADC) in the classification of solid nodules of brain parenchymal tuberculosis and response evaluation of patients.Methods Brain parenchymal lesions of 128 patients,with clinically and (or) pathologically confirmed brain parenchymal tuberculosis were analyzed retrospectively.Results Significant differences were observed in the average ADC values between enhanced areas and edematous areas of homogeneously enhancing and ring-enhancing lesions in all 128 patients before treatment(P<0.05).In 52 patients, the average ADC values of enhanced areas and edema areas in homogeneously enhancing and ring-enhancing lesions were significantly different before and after the treatment(P<0.05).Conclusion The ADC values in different areas of solid nodules of brain parenchymal tuberculosis are different, so can be used as a supplement to magnetic resonance imaging diagnosis and classification.After anti-tuberculosis treatment, the ADC values can be used as an observational indicator in follow-up.
