You should not drink any liquids containing sugars or calories for several hours before the scan. Tell your doctor about all the medications you are taking. If the tissue is viable, you may benefit from a PCI or coronary artery bypass surgery.

When you come to the Heart Institute, please check in with central registration in the front lobby. All of the six volunteers were men and were nonsmokers. SNR over OSEM, which may potentially be helpful when looking at scar tissue and ischemia.

MRI for the assessment of myocardial viability. Relative radiotracer uptake assessment with SPECT will miss those patients, and quantitation will identify them better. Terminal arterioles perfusing the capillary bed are shown in the right panel. Symptoms such as chest pain, shortness of breath, and others during the administration of the stressor and in the recovery phase should be documented.
