[Abstract] Objective: To investigate the clinical application of fractional anisotropy (FA) and apparent diffusion coefficient (ADC) in MR diffusion tensor imaging (DTI) for intracranial tumor.Materials and methods: Conventional MRI and DTI were performed in 39 patients with intracranial tumor (12 cases of glioma, 10 cases of meningioma, 9 cases of Schwannoma, 8 cases of lymphoma) prior to tumor excision. All the patients have been confirmed by pathology. ADC and FA were measured and compared between different types of tumor. The reconstruction of diffusion tensor tracking (DTT) in lesions and normal regions were obtained.Results: The average values of FA and ADC in glioma, meningioma, lymphoma, Schwannoma were FA1: 0.318±0.0036, FA2: 0.45±0.052, FA3: 0.304±0.012, FA4: 0.0362±0.071; ADC1: 1.233±0.204, ADC2: 1.061±0.039, ADC3: 1.014±0.108, ADC4: 1.469±0.06. Meningioma shows the highest FA value, and Schwannoma shows the highest ADC value, while both values of FA and ADC in lymphoma were the lowest. The result shows significant statistical differences (α=0.05).Conclusion: FA and ADC value shows significant differences between different tumors. DTT is better in displaying displacement, invasion and damage of white matter tracks. It is valuable for making diagnosis and differential diagnosis, and providing evidence for determining surgical plan and postoperative follow up.
