Dynamic uptake pattern of 18F-labeled-Fe3O4@Al(OH)3 NPs or mMSCs labeled with these NPs. The static scans were reframed into 20 frames of 1 min and 8 frames of 5 min to study the uptake pattern of radiolabeled (RL) NPs and mMSCs over the time period of acquisition within a the liver and b the lungs. Uptake of RL NPs in the liver can be seen in both experimental groups as seen by the increase in mean standardized uptake value (SUVmean), with a slow decreasing trend at later time points. On the other hand, the first pass of RL NPs in the lungs can be visualized, while there is stable uptake of mMSCs after 2 to 3 min
