首先接受血管内栓塞治疗,之后利用功能MRI的DTI显示神经传导束与AVM的关系(D),分次射波刀治疗(3次照射,每天照射一次,中间休息1天),照射剂量22.5Gy/3F。联合治疗后,没有出现明显脑水肿,病人左侧肢体肌力逐步恢复正常。3年后复查DSA显示AVM缩小了90%(E、F、G、H)。病人继续观察随访中(引自《现代神经外科学》第...
入院后完善检查,排除禁忌后制作头颅面罩,用于头部固定。考虑到患者的病灶位于右侧基底节区,并已经出现左侧肢体运动障碍,因此病灶位于右侧锥体束周围,治疗过程中可能损伤右侧锥体束从而造成患者左侧肢体运动障碍加重,遂2016年3月31日患者在我...

MethodsA retrospective analysis of 24 patients with refractory epilepsy, admitted to our hospital from March 2011 to March 2014, was performed; the epileptic foci of these patients were adjacent to the language functional areas conformed by imaging before operation. Surgical resection was performed with...
brain tumor surgery outcomes. This is because DTI is able to image the scaffolding and connections of the brain CT and routine MRI cannot. DTI is a measurement of the diffusion, the movement, of water through the white matter (nerve axons) of the brain by use of a high field MRI ...
结果 32例BOLD-fMRI和DTI图清晰的显示了大脑皮层左右两侧运动功能区的位置、大小和移位情况，为确 定手术路径提供重要的参考依据；手术也取得比较满意的效果。结论 BOLD-fMRI和DTI在功能区及附近区域脑肿瘤的术前评估中具有重要 的意义。 【关键词】 Experimental Research on a Pre-bulit Module in Sellar ...
DTI是近年来在常规MRI技术和弥散加权成像(DWI)技术基础上发展起来的一种新的无创成像技术,能在活体显示脑白质纤维束走向。 磁共振DTI及DTT对脑肿瘤手术前、后的研究中山大学硕士学位论文一、磁共振DTI及DTT在术前脑肿瘤中的研究目的:1.探讨MR弥散张量成像(DTI)及扩散张量纤维束成像(DTT)技术显示良、恶性脑肿瘤与...
However, fiber tracking can identify most of the brain's white matter tracts. In this image, the arcuate fasciculus has been tracked, between Broca's and Wernicke's areas of language. Fiber tracking Limitations The diffusion tensor imaging model assumes that, in each voxel, there is a ...
