A member asked:
Tsh low but normal t3 (liothyronine) n t4 my endo still suggest ultrasound and iodine 123 is that necessary ?
A doctor has provided 1 answer
Yes: Your endocrinologist is making sure that you do not have an overactive thyroid which may be caused by a lesion on the thyroid. The ultrasound will look for nodules and the iodine 123 will tell if the nodule is producing excessive hormones.
