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.

We report our experience of successful hemostasis after dental extraction with the use of rFVIIa in a FVII deficient patient. Preoperative PT% was 25%, and FVII was less than 3%. Thirty minutes before tooth extraction, 1.2 mg of rFVIIa was injected. At the beginning of the operation, PT% was more than 200%, FVII was 336%, and the hemostasis after dental extraction was excellent. rFVIIa was used effectively and safely for dental extraction in this case of FVII deficiency.
