Tiny red and blue dots on ultrasound

Hormones
1

I had an ultrasound done yesterday as my antibodies are extremely high for the past 6+ months. I had a hard time watching the screen, but at one point, I saw dozens of tiny red and blue dots on the screen. They were about the size of a pen dot, small and scattered, but not in a huge area. More like in the center of the screen. I was told that the red and blue represented blood flow, but what does it mean? They were quite small dots. Any ideas?

Thanks

On your thyroid?  I believe that the only parts of the thyroid that show well on a scan are the inflamed parts.  My whole thyroid showed easily, giving a definite diagnosis of Graves Disease.  So I am guessing that only part of your thyroid is inflamed and don't know enough about it to be able to say why.

Thanks. I do know I have Hashimoto's as my antibodies are over 1000 and lab says under40.  I also know she was measuring things but not sure what.

I've believe it's blood flow. Blue and red and flow either towards the probe ir away from the probe. I think it must be an ultrasound using a dopler.

it measures blood flow.
