| Outline of Final Research Achievements |
In this research project, by image engineering approach, we aimed at support of diagnosis of amyotrophic lateral sclerosis (ALS), which is one of designated intractable diseases. We realized an automatic recognition of whole-body skeletal muscles and an automatic analysis of fat in skeletal muscle region. Here, we fully automated the recognition of skeletal muscles in whole-body CT images and developed the site-specific automated analytical technique for patients with muscle diseases accompanied by ALS and muscular atrophy. Automatic recognition of surface muscle by modeling the body cavity was performed, and the whole body was divided into 22 areas, and also three dimensional analysis of skeletal muscles was achieved. As a result, significant differences were found in multiple image features between the ALS and the myogenic disease group in the upper arm, thigh and lower leg.
