Recently, a series of studies reported that low injection activity of 18F-FDG or a shorter scan time of total-body PET/CT imaging could still be feasible for good image quality [6–9]. Additionally, influence factors of image quality were varied and complicated, such as PET equipment, ...
If there is clinical deterioration, an earlier scan can be performed. Finally, a scan should be performed prior to discontinuation of immune checkpoint inhibitors so that accurate assessment of subsequent progression can be made. Despite some diagnostic uncertainty due to systemic inflammatory response ...
(b) On the first post-treatment FDG PET-CT scan, the node has decreased in size and activity following but is still evident (white arrowhead) and has surrounding inflammatory changes and fat stranding; (c) Follow-up FDG PET-CT scan 3 months later shows complete resolution of the node and...
