Dynamic PET measures the time-dependent spatial distribution of tracers in blood and tissues, enabling quantification of physiological parameters at the individual voxel level. But though many clinical PET protocols now involve whole-body acquisitions using multiple bed positions, the complexity of dynamic PET data acquisition means that such scans have been constrained to single bed fields-of-view. Whole-body dynamic PET has not yet been employed in routine clinical imaging.
To address this challenge, a US-Swiss research team has developed a parametric imaging method for whole-body dynamic PET. Their dynamic PET parametric imaging framework involves four to six whole-body passes. Read more.
