Investigations in SSTR2-positive pheochromocytoma allograft mice demonstrated that the albumin-binding [64Cu]Cu‐NODAGA-cLAB4‐TATE has favorable pharmacokinetic properties resulting in increased uptake and retention in tumors compared to its non-albumin-binding counterpart. Here, ALB is linked to hereditary pheochromocytoma-paraganglioma.
