(This is part 4 of a series. Click here to read part 1 ) Did you know there is a branch in the medical field called nuclear medicine? I didn't until today. Cool, huh? So a week ago I received a call from my endocrinologist to tell me my Thyroid Stimulation Hormone (TSH) levels were high enough that we could go forward with the radioactive iodine therapy. Shortly after that I received a call from the hospital to schedule, and not wanting to miss my first week of teaching seminary, we settled on today.
