研究目的:

胎肺成熟程度与其出生后的肺功能密切相关,因此早期准确评估胎肺成熟度可指导临床医生治疗并改善新生儿预后,减低新生儿期呼吸系统疾病的发病率。本课题拟联合多种超声模式综合评估产前胎肺成熟度,为今后指导临床用药及预测新生儿呼吸系统疾病提供一项影像学参考依据。  

Objectives of Study:

The degree of fetal lung maturity is closely related to its lung function after birth, so accurate assessment of fetal lung maturity at an early stage can guide clinicians in treatment and improve the prognosis of newborns, and reduce the incidence of respiratory system diseases in the neonatal period. This study aims to comprehensively evaluate fetal lung maturity before birth by combining multiple ultrasound modes (two-dimensional ultrasound, three-dimensional ultrasound, and shear wave elastography) to provide an imaging reference basis for guiding clinical medication and predicting respiratory system diseases in newborns in the future.
