I had a thyroid ultrasound done today and I'm just curious if anyone knows what all they measure and what it means. I understand they assess its overall size, but I did notice the technician measuring several, round, lsort of bean-sized, dark black spots. she probably took about 30 images all told. I've had surgery on my thryroid once, they removed a nodule on the right side, but I never saw the ultrasound images because they did the fna at the same time. I'm just wondering if there's normally black areas they measure or if I've got some little nodules again. my doctor says my thyroid levels are all normal, but I've been having problems with appetite, bradycardia, sleeping etc lately.
any info would be appreciated.. I'm very curious
