Abstract

The use of^{5 5}Co for positron emission tomography (PET) is criticized on the grounds that its 477 keV γ-rays would interfere with the positron annihilation measurements. This interference will lead to distorded pictures, lower resolution and lower tumor-non tumor ratios for^{5 5}Co-bleomycin. It is suggested that^{5 7}Co-bleomycin used in single photon imaging is better replaced by^{5 7}Ni-bleomycin rather than by^{5 5}Co-bleomycin for PET studies.
