The substance used in this examination seeks into the tissues of the body that use sugar. Normally, the cardiac muscle uses a lot of sugar, but it can also use fatty acids. A special diet can be used to decrease the normal sugar intake of the myocardium to provide the optimal condition for imaging. The diet contains plenty of proteins but very little carbohydrates. A failed diet may hinder interpretation of the results, so you must follow the diet carefully. On the day preceding the examination, you must keep a meal diary (ATTACHMENT).
