A MUGA Scan is used to evaluate the function of the heart. Patients undergoing chemotherapy have this exam to ensure that they will be able to tolerate the therapy.
There is no preparation needed prior to this exam. After registration and once you are in Nuclear Medicine, you will have an IV inserted into a vein in your arm. The technologist will draw blood out through the IV to be "tagged" with the medicine. You will wait for 30 minutes while the tagging process is completed.
The technologist will then reinject the blood that has been tagged back through the IV. You will then be asked to lie on a table and hold still while the scanner remains stationary over your body, which takes approximately 30 minutes.
If you are having chemotherapy later that day, the technologist will leave the IV in your arm.
