Ultrasound Measurements of Thyroid Gland Volume at 36 Weeks’ Corrected Gestational Age in Extremely Preterm Infants Born before 28 Weeks’ Gestation

摘要

BackgroundThyroid ultrasound is a non-invasive imaging tool and provides good evaluation of thyroid anatomy, location, vascularisation, and echogenicity. The aim of this study was to assess thyroid function and thyroid volume in extremely preterm infants born before 28 weeks’ gestation evaluated at 36 weeks’ corrected gestational age (CGA) compared to term infants’ normative data in the literature.
