Electronic off-peak status of one head of a dual-head gamma camera resulted in bone scintigraphy artifacts and faulty findings on gated myocardial SPECT
WJ Shih, T Schoenstra, K Gross… - Journal of nuclear …, 2003 - Soc Nuclear Med
Objective: Gamma cameras contain energy discriminators that allow only those photons within
a specified energy range to be recorded. A spontaneous shift in peak of 1 head of a dual-…
