Advantages of ultrasound as a diagnostic tool are many. The patient experiences no discomfort, nor does she feel any sensation. The patient can be examined without moving from her bed. Unlike x-ray, there is no danger of exposing the fetus and the mother to adverse effects of radiation. Its application in determination of fetal death, early in pregnancy, diagnosis of hydatidiform mole and localization of the placenta in cases of antepartum hemorrhage are only some of the obvious applications of this method.
超声作为一种诊断工具,优点众多。患者不会感到不适,也不会有任何感觉。患者无需离开病床即可接受检查。与X射线不同,不存在将胎儿和母亲暴露于辐射不良影响的风险。它在妊娠早期确定胎儿死亡、诊断葡萄胎以及前置胎盘出血病例中胎盘定位方面的应用,只是该方法一些明显的用途。
