摘要：
The aim of this fMRI study was to evaluate the motor reorganization (cerebral plasticity) and the risk of motor deficit in patients presenting with tumors and vascular malformations, within the framework of their pre-surgical planning. Functional MR imaging data was obtained from 17 patients. Ten patients (seven with tumors and three with vascular malformations) presented with motor reorganization. The results of the present study suggest that the evaluation of the cerebral reorganization is an essential step in predicting the risk of motor deficit in patients having surgical indication for treatment. Furthermore, the cerebral reorganization constitutes an important factor for surgical decision. (C) 2002 Elsevier Science Ireland Ltd. All rights reserved.
