Drink at least 8 glasses (8 ounces each) of decaffeinated liquids a day. Beverages include water and drinks in the low iodine diet guidelines.

The first week you will have blood work and scans and then receive your treatment. During the second week, you will have a post-treatment scan. The schedule generally looks like this:
