Forty-four fetuses were studied sonographically because of an elevated amniotic fluid alpha-fetoprotein level noted during routine amniocentesis, questionable findings during an ultrasound examination at another institution, or a history of a neural tube defect in prior pregnancy. Eleven neural tube defects, 16 non-neural tube defect anomalies, and 17 normal fetuses were all correctly identified by sonography. Ultrasound answers the need for a second diagnostic tool to complement the alpha-fetoprotein measurement.
由于在常规羊膜穿刺术中发现羊水甲胎蛋白水平升高、在另一机构进行超声检查时发现可疑结果或既往妊娠有神经管缺陷病史，对44例胎儿进行了超声检查。超声检查正确识别出11例神经管缺陷、16例非神经管缺陷异常和17例正常胎儿。超声满足了作为第二种诊断工具以补充甲胎蛋白测量的需求。
