In myocardial perfusion imaging, after high-level stress exercise it is recommended that SPECT imaging begin when respiration has returned to normal to avoid

Question

Quizplus · Accepted Answer

After high-level exercise (>10 METS), SPECT imaging should not commence until respiration has returned to normal.This will eliminate an artifact caused by a change in the extent of diaphragmatic excursion during SPECT acquisition.This phenomenon of upward creep typically results in an artifactual lesion in the inferior or inferoseptal regions of the left ventricle.
