Would hashmitos or graves disease show up on a thyroid ultrasound ?

Often not different: Sonographic features and vascularity of nodular Hashimoto thyroiditis is extremely variable.Thyroid gland can be nodular or normal. Graves (hyperthyroidism) usually has homogeneous appearance.

Maybe: Hashimoto's disease is auto immune thyroiditis. it is diagnosed clinically and by thyroid auto antibodies such as antithyroglobulin antibodies and antithythroid microsomal antibodies. It may be inferred on a ultrasound. Hyperthyroidism is diagnosed clinically, by lab. and by a 24 hour RAI23 uptake and scan.
