Representative planar scintigraphy scans (a,c) and combined optical/scintigraphy images (b,d) of a healthy mouse at 5 min and 60 min post-injection of [177Lu]Lu-f-MVPIK(Ahx-DOTA)I conjugate. The tracer is rapidly excreted via the renal pathway with the majority of the activity already being in the bladder after 5 min. No substantial uptake was noted in healthy organs. Of note, the scale bars between the scans at 5 and 60 min are different due to the different amounts of activity remaining in the mouse. (e) Ex vivo biodistribution data of [177Lu]Lu-f-MVPIK(Ahx-DOTA)I in healthy mice (n = 3) at 60 min post-injection.
