This is Dr. David

high signal on an MRI scan can be on T1 weighted image or T2 weighted image.

inflamed cysts in the thyroid gland can be bright on T2 weighted images.

active thyroid nodules producing thyroid hormone can be bright on T1 weighted images.

this doesn't necessarily mean you have a thyroid cancer in your thyroid

most thyroid cancers are very slow growing and many can be watched and not treated.

but your doctor should follow up and get an ultrasound scan of your thyroid gland to check on the gland and nodules and see how large it may be

nodules larger than 1 or 1.25cm in size may need a biopsy to know for sure what is in there

let me know if you have questions.
