Abstract :
An automated blood sampling system has been constructed and evaluated for use with positron-emission tomography (PET). The dispersion functions of two different detector units in the blood sampling system are compared. One is a plastic scintillator, and the other is a coincidence detector. No significant differences were found. Results from studies of blood-brain barrier transfer of a C-11 labelled receptor antagonist are discussed.<>
