PET analysis of [44Sc]3 in Wistar rats. a Maximum intensity projection (MIP) of rat administered with 2 1 h prior to administration of 12 MBq of [44Sc]3, 4 h p.i of radioactivity; sh shoulder, el elbow, wr wrist. b MIP of rat administered with saline 1 h prior to administration of 12 MBq of [44Sc]3, 4 h p.i. of radioactivity. c TAC of radioactivity uptake in the muscle (background grey circles), left shoulder (red triangles), and right shoulder (burgundy triangles) of rat pre-treated with 2 1 h prior to administering [44Sc]3. d TAC of radioactivity uptake in the muscle (background grey circles) and left shoulder (red triangles) and right shoulder (burgundy triangles) of rat pre-treated with saline 1 h prior to administering [44Sc]3. Three different ROIs were drawn for each shoulder to calculate the uptake value for the region
