| Research Abstract |
In this study, the imaging technique by the segmental acquisition method to optimize the visualization of the cancer lesion in the nuclear medicine tests was studied. As a result of optimal reconstruction algorithm in FDG-PET tests with short acquisition time, FORE+OSEM reconstruction might be useful under short acquisition time. Then, we evaluated the usefulness of the segmental acquisition method in clinical FDG-PET tests for rectal cancer patients. According to our study, the segmental acquisition method allows better detection of lesions and image quality than the conventional continuous acquisition method. The segmental acquisition method appears likely to be useful for clinical FDG-PET tests.
