Ultrasound imaging or sonography is based on the priciple of piezo-electric effect.Sound waves are produced by a piezoelectric crystal and images are produced by sound waves being reflected by various organs in the body.It does not use any ionizing radiation.
It is used in pregnancy to determine following things-
Number of fetuses, lie, presentation, fetal maturity, placental localiztion, liquor and congenital anomalies.
Evaluation of early preganancy requires a full bladder (oops!!!) and it is not essential for later stages of pregnancy. Nowadays even three dimensional and four dimensional (3D in real time) are also available which can give 3D representations of fetal face, spine and various congenital anomalies and give the parent an oppurtunity to decide after seeing the baby.
Doppler US can also be used especially in high risk mother like Pregnancy induced hypertension and IUGR to assess utero-placental and fetal blood flow dynamics.
Please note-ultrasound cannot identify all fetal abnormalities. It can determine the sex of the baby (but telling the sex of the baby is illegal in India!!)

I had to go back for a repeat Mammogram on my right breast. I have calsification and have for years. I usually get a call back but this time they said I have more and I have Implants. The Radiologist feels it is just Calsifiction and not to worry but the small area behind the implant they want to check the tissue. I am very sick and nervous and suffer with anxiety. I have to go for an MRI and I just want to know do you think it would be serious? Would the Radiologist have said to be concerned? he told me he didn't think it was anything to worry about.
Please let me know.
