Do the association between hypoechogenicity or irregular echo pattern at thyroid ultrasonography and thyroid function in the general population?
We demonstrated an association between hypoechogenicity at thyroid US and higher levels of serum TSH even in subjects without overt thyroid disease, suggesting decreased echogenicity as an early sign of thyroid dysfunction. Irregular echo pattern, whether accompanied by hypoechogenicity or not, was another possible marker of thyroid failure. This indicates a possible use of thyroid US in detecting early and subclinical thyroid dysfunction.
Our results support the conclusion of a very limited impact of ABVD chemotherapy on brain metabolism in patients with HD.
