摘要： 末次月经作为计算孕龄的常用手段，计算方法简单，经济成本低，但该方法存在诸多缺陷。超声检查近年来越来越受到重视，其计算孕龄较末次月经有着明显优势，并且已被众多机构推荐为首选计算孕龄的方法。超声检查的指标选择及计算公式在不同地域均有差异，因此各地也在摸索适合本地人群的数据资料，但针对中国大陆人群尚无数据资料。综述末次月经和超声检查计算孕龄的特点及超声评估孕龄的具体方法，为产科处理提供更好的依据。

Abstract: Last menstrual period（LMP），which is a common means of estimation of gestational age，is simple，economical and low-cost. However，this method has many defects. Studies have demonstrated ultrasonography measurement to be superior to the LMP in estimation of gestational age and is receiving more and more attention. It is becoming the preferred choice for estimation of day of delivery in many countries. There is clinically significant difference among areas when determining gestational age on the basis of ultrasonography measurement. But there is no a sonographic dating formula based on ultrasonography measurement in Chinese population. This paper reviews the LMP and ultrasound characteristics and calculate gestational age ultrasound assessment of gestational age specific method for processing to provide a better basis for obstetrics.
