Cardiac positron emission tomography (PET) perfusion images for two sleep apnea patients.

Caption

Cardiac positron emission tomography (PET) perfusion images for two representative patients. Both patients had similar demographic characteristics. Neither patient had significant perfusion abnormalities as shown in the figure. Patient A had mild sleep apnea while patient B had severe obstructive sleep apnea. The corrected myocardial flow reserve (MFR) for patient A was normal at 3.24 while for patient B it was severely abnormal at 1.22.
