title: Measurements of an index of echogenicity in some thyroid diseases.
abstract: In the preceding article, the measurement of an index of echogenicity has been described. In this article, we present the mean value and standard deviation of this index in normal thyroid and pathological cases. It appears that the index is very significantly lowered in Hashimoto's disease compared to its value in normal thyroids and simple goiters. The advantage of this index in other cases such as Graves' disease, subacute thyroiditis, and thyroid nodules is discussed.
