text: Right-angle dual-headed tomography,
  Cardiac SPECT utility, cutting time in half, oh, what a story!
  Enhancing gating capabilities, that's the goal,
  But when the heart rate decelerates, it takes a toll.
  
  Returnin' to baseline rate after stress or lessened anxiety,
  Last step(s) of a gated study affected, can't you see?
  Possible frame loss, information on the line,
  Let me break it down and illustrate, make it shine.
  
  Myocardial perfusion studies, artifacts they produce,
  Frames lost in single- and dual-detector SPECT, that's the truth.
  Imaging methodologies, oh, what a mix,
  But we gotta understand the risks, that's the fix.
