摘　　要：超声波可以通过生物学效应作用于人体及动物的器官组织、细胞超微结构甚至细胞因子,引起它们的变化乃至损伤,这种变化与超声辐射时间及强度成正比。诊断超声引起组织细胞的凋亡是近期效应、是可逆的,并且分子水平的损伤具有累积效应。孕期是器官组织、细胞的敏感时期,最易受到外界影响,所以孕期超声检查要尽可能使用最低剂量的原则。Ultrasound is biologically active and may cause the alteration and injuries in human and animal organs,tissues,cellular ultrastructures and even cytokines,proportional to the exposure time and intensity.Diagnostic ultrasound results in the acute and reversible apoptosis in cells and becomes accumulated at the molecular level.In pregnancy,organs,tissues and cells are highly sensitive and subject to the environmental interference.Therefore,the dosage of ultrasonography should be minimized for the pregnancy examination.
