title: [Motor cortex by real-time imaging process functional MRI during finger movements].
abstract: OBJECTIVE
  To explore the techniques of RTIP-fMRI scanning and the correspondence between structure and functional changes of motor cortex during self-paced finger movements by RTIP-fMRI in normal volunteers.
  
  
  METHODS
  The 15 healthy volunteers were studied by RTIP-fMRI, and the activation tasks consisted of self-paced finger movements performed with the right and the left hands. Image postprocessing was done on the workstation by "correlation coefficient" algorithm analysis method, IAC and SPM software.
  
  
  RESULTS
  There was a good correspondence between the anatomical landmarks of the somatotopical organization of primary motor areas in the 15 volunteers; during the finger tasks, the functional changes occurred in the contralateral primary motor-somatosensory cortex (M1/S1), the supplementary motor area (SMA), and the ipsilateral primary motor cortex.
  
  
  CONCLUSIONS
  RTIP, a promising new technique, can localize the motor cortex accurately. It is superior to any other fMRI techniques, and may be used widely in the function research of the brain.
