[Grey value analysis of the ultrasonic image of the thyroid in children]

Simultaneously with the sonography of the infantile thyroid gland in addition to the description of the echo texture we tried to elaborate with the aid of a grey-value analysis quantitatively comparable parameters for healthy thyroid glands. The thyroid gland of newborn showed by 17.4 the lowest mean grey-value. In schoolchildren it ranges between 25.5 and 31.0. Consequently the differences in grey-values objectively found out may be of use for diagnostics of thyroid diseases in infancy by the fact that before the rear of values dependent on age abnormalities will become better percentile.
