摘要：

Functional MRI motor mapping was performed in two women with unilateral high- grade stenosis of the middle cerebral artery ( MCA) to determine the influence of impaired hemodynamics on the blood oxygenation level dependent ( BOLD) response. In both patients no structural lesions were present in primary motor pathways. A redistribution of the motor network to the healthy hemisphere was the main indicator of chronic hemodynamic compromise.
