Abstract (in Japanese) (See Japanese page) 
(in English) The purpose of this study is to develop a technique for the computer-aided diagnosis (CAD) system to track lesions by analyzing their temporal changes on torso FDG-PET scans. In this study, we created normal statistical models by using 243 normal scans, and detected abnormal accumulations in each examination. Our detection scheme resulted in 82.6% true-positive rate with 12.4 false-positive marks per scan. We applied this method to 58 cases with temporal changes. Our result showed that our temporal subtraction method would be useful for detecting interval changes on torso FDG-PET scans.
