Frequently asked questions about Ultrasound (USG)
Is ultrasound safe in pregnancy?
Yes. Ultrasound uses sound waves, not radiation, and is the standard method for monitoring pregnancy.
Why do I need a full bladder for a pelvic ultrasound?
A full bladder pushes the bowel out of the way and acts as a window, giving clearer pictures of the uterus, ovaries, prostate and bladder.
Is sex determination done?
No. Sex determination of the foetus is illegal under the PC-PNDT Act and is not done.
