Several factors.: John, the main factors i consider in determining rai dosage are: surgical pathology results, what does the rai scan look like (extent of disease, amount of thyroid tissue present), and how high is the stimulated thyroglobulin level. I basically try to get a sense of how bad a person's cancer is, and what my range for giving a safe but effective rai dose would be. Hope this helps.
