PDFAbstract
Objective To investigate the value of high field magnetic resonance diffusion tensor imaging (DTI) technique in malignant brain tumors. Methods Five cases of malignant meningiomas, 15 cases of gliomas and 30 cases of metastases were scanned by AX3DFSPGR and diffusion tensor imaging (DTI). The apparent diffusion coefficient (ADC) Value and anisotropy fraction (FA) were post-processed and reconstructed. The white matter fiber bundles in the tumor parenchyma area, edema area and peritumor white matter area were measured and analyzed. Results Malignant brain tumor edema area, peritumoral white matter fiber bundles were destroyed, interrupted, the incidence of white matter damage around the tumor and the tumor is proportional to the degree of malignancy. Conclusion Diffusion tensor imaging (DTI) has important application value in differentiating intracranial malignant tumors.
