Coincidence and noncoincidence counting (81Rb and 43K): a comparative study.
This paper compares the accuracy of imaging and resolution obtained with 81Rb and 43K using coincidence and noncoincidence counting. Phantoms and isolated infarcted dog hearts were used. The results clearly show the superiority of coincidence counting with a resolution of 0.5 cm. Noncoincidence counting failed to reveal even sizable defects in the radioactive source.
