Many reports say that DWI (diffusion-weighted-image) is very useful for the diagnosis of cerebral infarction, especially in the acute phase, but it is difficult to have a fine image because DWI is very sensitive to artifacts caused by the “body-move” of the patient.
About the degree of MPG (motion probing gradient), criteria are yet to be established. Many persons try in their own way. With MPG5, the intensity of CSF and that of the focal lesion are almost equal, so that it is difficult to distinguish infarcts from adjacent ventricles.
The stronger the degree of MPG is, the more artifacts or noises we get, We recommend MPG6 or 7 in the right-left direction.
