Objective To study and analyze the MRI manifestation of miliary tuberculosis of the brain.Methods Twenty-two cases with cerebral miliary tuberculosis of the brain were retrospectively studied with MRI including plain scan and enhanced study with GD-DTPA MRI features regarding the size,shape and distribution of the lesions were summarized and analyzed.Results Miliary tuberculosis of the brain was found most frequently at the junctional area of white and gray matter.The diameter of the lesion was less than 3 mm,therefore,plain scan often failed to display the lesions,however,markedly enhanced tubercles could be demonstrated on enhanced scan.Conclusion Enhanced MRI scan proved to be very helpful in the early detection of miliary tuberculosis of the brain.

Evidence-based medicine (EBM) is a science that uses the best available research data to make decisions, and the core is that clinical decision-making is supported by the best research evidence. Incorporating EBM into traditional standardized residency training in hematology can foster residents' professional theoretical knowledge and clinical skills, improve the quality of standardized training, and provide ideas and methods for standardized training of hematology residents, which is worthy of further research and exploration.
