| Research Abstract |
This purpose of this study was to develop a new method for quantitative analysis of standardized uptake value (SUV) of positron emission tomography scan images. Our scheme consisted of 2 approaches, which included the construction of a normal model and the determination of the SUV score. To construct the normal torso model, all of the normal scan images were registered into 1 model. After the organ and body region recognition, the body surface was deformed into the model by using a thin-plate spline technique. In order to determine the abnormality of SUV, we analyzed 243 (143 males and 100 females) normal cases to establish the normal model. We also extracted 432 abnormal spots from 63 abnormal cases. Our computerized scheme would be useful for visualization and detection of subtle lesions on FDG-PET scan images even when the SUV may not clearly show an abnormality.
