The invention belongs to the technical field of medical image processing and application, and relates to a frontal lobe language cortex functional area positioning method based on diffusion tensor imaging. The positioning method comprises the following steps: acquiring a preoperative structure and a DTI magnetic resonance image of a tested object; selecting ROI # 1 as a rear triangular area of a lateral ventricle posterior angle of a left hemisphere, selecting ROI # 2 as a left frontal lobe, and selecting ROI # 3 as a left apical lobule; combining the ROI # 1 and the ROI # 2 to reconstruct an arcuate beam, and combining the ROI # 2 and the ROI # 3 to reconstruct an upper longitudinal beam; combining the tail ends of the two fiber bundles to obtain a frontal lobe language cortex function area of the tested object; comparing the cerebral cortex Chinese language functional area based on the preoperative DTI with the language function positive site of the DCS under the wake-up operation, and calculating the sensitivity and specificity based on the positioning method. The method is simple and convenient to operate, easy to popularize and high in sensitivity and specificity; deviation and invasive operation of cortex electrical stimulation in an operation can be effectively avoided, and perfect guidance can be provided for a clinical operation.
