What's a Mugu?

It's a rather bizarre heart test. Or maybe it's just the prep that's bizarre: they take some of your blood out, take the iron out of that blood, put radio-isotopes into that blood, then put the blood back into you.

Then they just take lots and lots of pictures of your heart, using the radioisotopes to get prettier images. Which wouldn't be so bad except that each set of pictures takes six or seven minutes, you're in a darkened quiet room, and apparently, if you fall asleep and then jerk awake in the middle, they have to start that set over - ahem, I did that a few times.

This test gives them a baseline reading of my heart's ability to squeeze, so they'll know that it's strong enough to handle chemo - and later, so they'll know whether the chemo hurt it. Oh joy.
