This was a retrospective study of TPO - Ab concentrations in 36 women and 2 men (mean age 51 + / - 16 years; range 19 - 81 years) with Hashimoto's thyroiditis as defined by the following criteria: elevated plasma TPO - Ab and typical hypoechogenicity of the thyroid in high - resolution
sonography at first presentation or during follow - up and low pertechnetate uptake in thyroid scintigraphy.
Sonographic technology is expected to evolve rapidly and to spawn many new
sonography procedures, such as 3 - D
sonography; however, high costs may limit the rate
at which some promising new technologies are adopted.
