Measuring myocardial blood flow using dynamic myocardial perfusion SPECT: artifacts and pitfalls.Dynamic acquisition allows absolute quantification of myocardial perfusion and flow reserve, offering an alternative to overcome the potential limits of relative quantification, especially in patients with balanced multivessel coronary artery disease.  SPECT myocardial perfusion is widely available, at lower cost than PET.  Dynamic cardiac SPECT is now feasible and has the potential to be the next step of comprehensive perfusion imaging.  In order to help nuclear cardiologists potentially interested in using dynamic perfusion SPECT, we sought to review the different steps of acquisition, processing, and reporting of dynamic SPECT studies in order to enlighten the potentially critical pitfalls and artifacts.  Finally, published data enlighten some facets of dynamic cardiac SPECT while several issues remain.
