Cells can be damaged by diagnostic ultrasound. While I may not know much about the brain, I do know that when building the house the foundation is the most important.
Similarly, early parts of fetal development are sensitive and disturbance could have long term consequences.
If diagnostic ultrasound is capable of causing cellular damage, then the downstream effects of this definitely deserve further investigation.
To evaluate the effects of diagnostic ultrasound on villus ultrastructure of early pregnancy.
Using the electron microscopy, the effect of B-mode ultrasound and color Doppler flow image on villus of early pregnancy were studied. 46 cases of early pregnancy women were divided into five groups: Groups 1 : control group; Group II and III: 24 +/- 1 hours after exposure to B mode and color Doppler ultrasound for 30 minutes respectively; Group IV and V: 72 +/- 1 hours after exposure to B mode and color Doppler ultrasound for 30 minutes respectively.
Expansion of perinuclear space in cytotrophoblasts and syncytiotrophoblasts, enlargement of rough endoplasmic reticulum, and vacuolization in the cytoplasm were found in Group II and III.
The present study showed that the main injured sites after exposure to ultrasound were the plasma membrane and suborganelles. These changes disappeared within 3 days.
