Abstract:
Objective To discuss the application of DWI and DTI in diagnosis and evaluation of brain tumor. Methods Combining with literatures, the application of DWI and DTI in brain tumor diagnosis, differential diagnosis, tumors classi- fication, preoperative evaluation, operation plan establishment, follow-up role of treatment were reviewed and evaluated. Results The DWI and DTI were available to brain tumor diagnosis, differential diagnosis and tumor grade. The DTI could be clearly shown the influence of tumor with white matter quality, it was important in operation plan establishment. The combination of intra-operative MRI, functional MRI and DTI was valuable for brain tumor resection. In the meantime, the treatment response of tumor and the changes of treatment-induced white matter were accurately assessed by DTI. Conclu- sion With the MRI hardware and software technology development, the DWI and DTI imaging information can be provided important value in brain tumor pathological changes diagnosis, evaluation, therapeutic planning and post treatment assess- ment.
