Functional MR Imaging of the Motor Cortex in Active and Passive Movement: Qualitative and Quantitative Changes
2002
Journal of the Korean Radiological Society
Purpose: To compare functional MR imaging of the motor cortex during active and passive movement. Materials and Methods: Seven healthy, right-handed volunteers (M:F=6:1; age:25 30 years) were included in this study. A 1.5-T whole body scanner and the multislice EPI BOLD method were used. The motor paradigm was flexion-extension of a thumb against rest. In the active motion task, the thumb was flexed voluntarily once a second, while in the passive task, it was tied with a thread and pulled to
