Dynamic Whole-Body 18F-FDG PET for Minimizing Patient Motion Artifact

Recent PET/CT systems permit short acquisition with acceptable image quality. In addition, continuous-bed-motion mode is available for whole-body PET imaging with some PET cameras providing better uniformity and reproducibility throughout the field of view. We demonstrate a case with patient motion during the dynamic scan. Although the total summation of serial whole-body scan showed image artifact, the first 15 minutes' summation of the serial scans provided high-quality images by eliminating the frames with motion. This acquisition mode seems to be particularly useful to perform for those who may likely to move during PET scan.
