Abstract Although two-dimensional tomographi images of X-ray CT and MR imaging have brought great improvements in diagnostic efficacy, they do not allow external inspection of organs. It is important to precisely identify gyri in terms of the relationship between anatomy and function of the brain. In three-demenshional images, identification of gyri and sulci is very easy and accurate. We developed software that automatically extracts the brain matter from thin-sliced coronal MR images. This software simultaneously generates volumees and three-dimensional volume-rendered images of the brain. The results of comparing patients with dementia and healthy subjects were good in the qualitative visual evaluation and the quantitative volume evaluation.
Keywords MRI, 3-dimensional image, brain volumetry, dementia
