One hundred twenty infants ranging in weight from 600 to 4,000 grams were entered into a prospective sonographic study to establish normal renal growth parameters. Renal cortical echogenicity was demonstrated to decrease with increasing infant weight. Observations on the use of Doppler analysis for assessing renal vascular flow are presented.
120名体重在600克至4000克之间的婴儿被纳入一项前瞻性超声研究，以确定正常的肾脏生长参数。研究表明，肾皮质回声随着婴儿体重的增加而降低。本文介绍了使用多普勒分析评估肾血管血流的观察结果。
