Is it important to find my thyroid. mri of head and neck did not show thyroid. i take 100mcg and 150mcg thyroxine alternate days?

Not important: Hi. No, it is not important to find your thyroid. You are effectively treated for hypothyroidism. We are assuming no neck scar and no diagnosis of congenital hypothyroidism, right? Your thyroid may be a small, atrophic little scarred down thing not seen on MRI. The only significance would be on the off chance that a mass in the thyroid developed, but by definition, that would be palpable or seen.
