Why the study?
Does a body-weight-dependent dose protocol provide more consistent image quality compared to a fixed dose in patients undergoing SPECT stress MPI?
Does a body-weight-dependent dose protocol provide more consistent image quality compared to a fixed dose in patients undergoing SPECT stress MPI?
A patient-specific, body-weight-dependent dosing protocol for conventional SPECT MPI provides constant image quality regardless of patient weight.
No takes yet. Share an insight, caveat, or question.
Fixed-dose protocols may reduce counts in heavier patients with conventional SPECT; leaves open need for weight-based dosing.
Dijk et al. (2015) studied this question.
