CAD System for Nuclear Medicine Brain Imaging

Abstract

The CAD system in the field of the brain nuclear medicine has been developed for diagnosis of dementia. The technique using voxel-based statistical analysis system has been developed and is used in the clinical study for brain glucose metabolic PET images and perfusion SPECT images. There may be few artifacts on the analysis process and it is always necessary to compare the findings with visual inspections. These methods have not yet established the evidence of good diagnostic performances. These techniques are expected to have high diagnostic accuracy and to be applied to other brain images: amino acid metabolic images, brain receptor images and amyloid images.
