摘要
本文应用超声检测８７例有宫内生长迟缓（ＩＵＧＲ）倾向的孕妇，为评价ＴＣＤ／ＡＣ比率对ＩＵ－ＧＲ的诊断可靠性进行了前瞻性研究。结果显示敏感性为８１％，特异性为８７％，阳性预测值８４％，阴性预测值７６％。ＴＣＤ／ＡＣ比率能脱离孕周计算独立评估ＩＵＧＲ，有其特殊价值。
A prospective study was conducted to evaluate the ability of the transverse cerebellar diameter/abdominal circumference ratio to identify growth retarded fetuses.Of the cases analyzed,48 of 87(55%)were growth retarded by birth weight. The TCD/AC ratio identified growth retardation with a sensitivity of 81%,specificity of 87% ,positive predictive value of 84%,and negative predictive value of 76%.The TCD/AC ratio can beuseful for the assessment of fetal growth retardation. however,the ratio may be normal in cases of severe fetal growth retardation.
