Bev, glad things are moving along. Perhaps not the direction planned on (is it ever with cancer...) but movement is good.
A MUGA scan is looking at the heart basically to a) make sure it's strong enough to withstand chemo and more importantly b) as a baseline incase the chemo is cardiotoxic. Many chemos are cardiotoxic so it's a good idea to have a baseline heart scan in case they get concerned down the track. They will label his red blood cells with some radioactivity and then re-inject them into his body and watch the heart as they get pumped around. It allows a good look at wall motion, sometimes chemo can affect the wall motion of the heart, making it 'lag' at the end of it's pump. It also produces a number called the 'ejection fraction' or EF. THis is the % of blood the heart pumps out (difference between when its full of blood and once it's pumped). This number should be over 50% for 'normal' heart function. Most people have an EF over 60%. Depending on the chemo they may repeat this scan over the course of his treatment. If the EF drops they may alter the chemo.
Hope this helps explain it a little. It's usually not looking to find things 'wrong' just to initially do a baseline and keep check on it over the treatment course.
Hoping you are both coping ok all things considered.
