Experience of brain checkup by MRI

Abstract

Purpose: We performed head MRI and MR angiography (MRA) to find asymptomatic central nervous systems (CNS) diseases and to prevent their development as a group health care. Methods: We performed 583 head MRI and MRAs since on March 1991 for the staff lived in Self Defense Force (SDF) Maizuru guard area whose age was 40 years, who reached the retirement age and had the risk factor of the cerebral vascular disease. Results: We found 119 subcortical lesions, 26 asymptomatic cerebral infarctions, 6 unruptured cerebral aneurysm, 2 pituitary adenomas, 4 venous angiomas. For 5 cases of asymptomatic cerebral infarction, we prescribed anti platelet agglutination drugs, there was no people whose disease became symptomatic. For unruptured cerebral aneurysms and pituitary adenomas, we did operation, everyone attained social rehabilitation. Before equipment of the MRI in SDF Maizuru hospital, 2 ruptured cerebral aneurysms occurs. There were no subarachnoid hemorrhage patient since our challenge started in SDF Maizuru guard area. Conclusions: It is useful to clarify the etiology of CNS disease and for group health care, using head MRI as medical checkup.
