| Abstract(in English) | The purpose of this study is to develop a technique for the computer-aided diagnosis (CAD) system in torso FDG-PET images. We constructed the CAD system that integrates two technologies of temporal subtraction and score image production. The doctor evaluated the effectiveness of integrated system of the two techniques. In the experiment, 21 normal cases, 11 good cases, and 26 malignant cases were employed all with temporal changes. The appropriateness of the temporal-subtraction image processing inclusion was evaluated by three stages as "appropriate", "unclear", and "inappropriate". As a result, the evaluations of appropriateness were 54 pairs (85%) for appropriate, 0 pairs (0%) for unclear, and nine pairs (15%) for inappropriate. It was found from this qualitative evaluation that the system developed was able to show the temporal changes of most of the diseased areas appropriately. |
