説明

Recently, the value of MRI has come to be recognized and its scope of application is broadening. It is used to examine the brain. The horizontal axial view to obtain a brain image is taken most frequently, so as to visualize its anatomy and make the comparison of X-ray CT images and MRI. We thus attemptted to advice away of taking images with OML take would allow reproducibility. We studied the relation between the nose root and OML by a cephalogram. And found the former to be probuged according to the latter regardles of age the nose is on the prolongation of OML without considering ages. OML from a patient was thus make to accord with a localizer and found to be situation in the center of a magnetic field. A median view was then taken to ditermine the location of what and the angle of the image by the line through the root of the nose to the cross point of the grid. In this possible to obtain images parallel to OML at any neck position with satisfactory reproducibility.
