| Outline of Final Research Achievements |
We have developed a prototype of computer-aided diagnosis system for FDG-PET images based on statistical image analysis. Fifty-five cases were employed to evaluate the initial performance. As a result of this work, we have achieved 95% true-positive fraction to detect abnormal spots and to track the activity changes between two time series examinations. The evaluation of activity changes of 76% examinations showed the same results as radiologists' comments.
In conclusions, the presentation of activity changes with SUV and Z-score will be a helpful index for the interpretation of FDG-PET images during the cancer treatment.
