The Stress MUGA test is a good indicator of coronary artery disease. The
patient is not to eat approximately four hours prior to the study. Some of
the patient's blood is drawn, mixed with UTRBC kit and 99 mtc. and then
reintroduced into the patient's body via IV. After the isotope is
injected, images are taken in three views for about 15 minutes. The
patient is then stressed with IV Dobutamine approximately 5 minutes. The
patient will rest until the heart rate returns to near normal. Another
five minutes of images are then made.
