 note = {In recent years, it is recognised that MRI has high avalability in the diagnosis of neurological diorders. MRI is superior to XCT for the reason of high quality. On the other MRI has some weak points such as the insensitivity of fresh bleeding, calcification, and bony disease adding to imaging artifact. In ischmic cerebrovascular, disease, MRI can detect the lesion in its early stage. Further small infarct (lacunae) are found in details by MRI. As a result of the investigation of sevral diseases accompany with diffuse white matter lesion (Binswanger dis. , radiation encephalopathy, Alzheimer type dementia), the exsistance of lacunae and the location of lesions were helpful to the defferentiation of the cause of it. Today it is known that MRI is very useful in the detection of MS plaque. We also confirmed it in our 16 MS cases, but we realized that for the detection of optic and spinal MS lesion, other diagnostic technique were as impotant comparatively. Flow related image is the most interesting application of MRI. Using fast MR image, we analyzed aqueductal CSF flow. In normal control, aqueductal signal was indicated as two peaks in the ECG RR interval. Phase related image showed that the second image was descending CSF flow from 3rd vetricle to 4th ventricle. In 4 cases of hydrocephalus ex vacuo, aquedactal flow could be observed normaly, on the other in 2 cases of aqueductal stenosis, aquedactal CSF flow weren't recognized yet. By our experiment it is avalabile to estimate the aquedactal CSF flow by this method.},
