Dynamic PET imaging of glycoclusters 1a, 2a, and 3a–c (a–e, respectively) in normal BALB/c nude mice. 68Ga-DOTA-labeled glycoclusters (10 MBq) were administered into the tail vein of the mice (n=3, 500 pmol, 100 μL/mouse) and the whole body was scanned by a small-animal PET scanner, microPET Focus 220 (Siemens Medical Solutions Inc., Knoxville, TN, USA), over 0–4 h after injection; H: heart; K: kidney; L: liver; B: urinary bladder; GB: gallbladder.
