Answer

A study by Ruchala et al indicated that sonoelastography may be useful in the diagnosis and differentiation of subacute, acute, and chronic autoimmune thyroiditis, and may be an effective means of monitoring treatment success in these disorders. The investigators compared thyroid tissue stiffness in 40 healthy control subjects with stiffness in 2 patients with acute thyroiditis, 18 patients with subacute thyroiditis, and 18 patients with chronic autoimmune thyroiditis.

Findings included higher thyroid tissue stiffness in patients with the subacute disorder than in the control subjects at baseline and when the disease was in remission. The thyroid tissue was also stiffer at baseline in the subacute subjects than it was in patients with chronic autoimmune thyroiditis but was less stiff during remission than it was in the chronic patients.
