Diagnostic x-ray studies during any stage of gestation have been shown to increase the risk of childhood cancer in the irradiated fetus. This study reviews those risks and examines the uses of pregnant abdomen and x-ray pelvimetry studies. The abdominal films appear to have provided useful and necessary information in the management of labors and deliveries; however, the x-ray pelvimetry results appear to have provided much less usable information. The predictive values of both positive and negative x-ray pelvimetry studies were low, .57 and .66, respectively. The predictive values were low for both vertex and breech presentations. The definite hazards of prenatal diagnostic radiation studies should be carefully weighed against their possible benefits.
妊娠期任何阶段的诊断性X线检查已被证明会增加受照胎儿患儿童癌症的风险。本研究回顾了这些风险,并探讨了孕妇腹部X线检查和骨盆测量检查的用途。腹部平片似乎为分娩管理提供了有用且必要的信息;然而,骨盆测量X线检查结果提供的可用信息要少得多。骨盆测量X线检查的阳性和阴性预测值都很低,分别为0.57和0.66。头先露和臀先露的预测值都很低。产前诊断性放射学检查的明确危害应与它们可能带来的益处仔细权衡。
