磁共振弥散张量成像是目前惟一可以在活体映射白质纤维束走行的无创的影像学检查方法,当白质纤维束受到胶质瘤不同程度的累及时,磁共振弥散张量成像能定性、定量地将之反映出来,从而指导术者术前准确评估胶质瘤的分级分期,并选择合适的手术方式,尽可能达到既最大程度地切除肿瘤,又合理地保护患者的神经功能。 Magnetic resonance diffusion tensor imaging is the only noninvasive imaging method that can be used to map the white matter fiber in vivo. When the white matter fiber bundle is affected by different degree of glioma, MR diffusion tensor imaging can qualitatively and quantitatively Will be reflected in order to guide the surgeon preoperative accurate assessment of glioma grading and staging, and select the appropriate surgical approach, as far as possible to achieve the maximum extent of tumor removal, and reasonable protection of the patient’s neurological function.
