Navigated transcranial magnetic stimulation for presurgical planning--correlation with functional MRI.

摘要: Purpose: This paper describes the potential of navigated trans- T cranial magnetic stimulation to map motor cortex in patients t with mass lesions near primary by comparing results this technique those functional MRI. Material and Methods: Ten central c sulcus were studied preoperatively using a figure-of-eight tran- scranial stimulator attached neuronavigation sys- tem allow for direct visualization stimulated brain regi- r on. Subsequently, all blood oxygenation level de- l pendent 2D multislice multishot 2 * -weighted gradient echo EPI sequence on 1.5 Philips Gyroscan during activation was p performed. Results both methods coregistered com- ( pared. Results: The distances between peak parenchymal fMRI cortical area where TMS elicited ma- u ximum MEPs ranged 0 1.2 cm (mean 0.6 cm, SD 0.4 cm). Conclusion: We conclude that is reliable alternative localizing motor-related areas human therefore may be useful adjunct or, selected patients, even helpful k
