[Current approaches to estimating the sizes of the thyroid in neonates and infants from ultrasonographic data]

Area of Science:

• Neonatal medicine
• Endocrinology
• Medical imaging

Background:

• Thyroid function is crucial for infant development.
• Preterm infants are at higher risk for thyroid dysfunction.
• Early detection of thyroid abnormalities is essential.

Purpose of the Study:

• To ultrasonographically assess thyroid gland dimensions and echogenicity in preterm neonates.
• To develop a standard formula for thyroid volume in newborns.
• To enable early diagnosis of neonatal goiter and thyroid hypoplasia.

Main Methods:

• Ultrasound examination of the thyroid in 384 preterm infants (4-8 days old).
• Comparison of thyroid echogenicity with the parotid salivary gland.
• Development of a statistical formula for individual standard thyroid volume.

Main Results:

• Established a formula for calculating the standard thyroid volume in neonates.
• Demonstrated the feasibility of using ultrasonography for early thyroid assessment.
• Identified variations in thyroid size and echogenicity in infants born to mothers with iodine deficiency.

Conclusions:

• The developed formula provides a reliable method for assessing neonatal thyroid volume.
• Early ultrasonographic evaluation can aid in diagnosing thyroid abnormalities in preterm infants.
• This technique is valuable for managing potential endocrine issues in newborns.
