X线是体格检查和医生诊断疾病的重要手段。尽管目前X线设备日趋完善,射线量逐渐减少,安全度不断增加,但毕竟仍存在某些副作用,对某些人可能有不同程度的损害,孕妇就是其中之一。由于胎儿对电离辐射相对敏感,造血系统及多个组织正处于发育阶段,故孕妇,特别是怀孕3个月以内者,如接受较大剂量X线直接照射,就有发生畸胎危险。当然,倘若病情特别需要,比如长时间咳嗽不愈,急需排除活动性肺结核,那就不能完全拒绝必要的X线检查,可以加强一些保护措施。有专家认为,孕期中,尤其是怀孕3个月以上偶尔进行一两次X线胸透或摄片,并不会增加胎儿畸形发生率,故孕妇对X线检查应该慎用,尽量少用,
X-ray is an important means of medical examination and physician diagnosis of disease. Although the current X-ray equipment is maturing, the amount of radiation is gradually decreasing and the safety is increasing, but after all, some side effects still exist and some people may have different degrees of damage. Pregnant women are one of them. As the fetus is relatively sensitive to ionizing radiation, hematopoietic system and multiple tissues are in the developmental stage, so pregnant women, especially those within 3 months of pregnancy, such as receiving larger doses of X-ray direct exposure, there is the risk of teratogenicity. Of course, if the special needs of the disease, such as prolonged cough unhealed, the urgent need to rule out active tuberculosis, it can not be completely rejected the necessary X-ray examination, you can strengthen some protective measures. Some experts believe that during pregnancy, especially in pregnancy more than 3 months occasionally once or twice X-ray chest radiography or radiography, and will not increase the incidence of fetal malformations, so pregnant women should be used with caution X-ray examination, try to use less,
