Residence times of source organs and remainder of body determined in nine healthy volunteers.

AIf all radioactivity remains in the body, the sum of all residence times equals 0.49 h for 11C.BAlthough this variance was high as a percentage, the mean residence time of the urinary bladder was itself quite small. The small residence time corresponded to accumulation of urinary activity of Fig. 2).CSalivary glands included parotid and submandibular glands. We list the residence time here for comparison with source organs. However, because OLINDA/EXM1.1 excludes salivary glands as a source organ, we attributed activity from salivary glands to remainder of body.
