What is an Ultrasound?

The term “ultrasound” refers to sound with a frequency that humans cannot hear.

Ultrasound is a sound that travels through soft tissue and fluids, but it bounces back off denser surfaces and creates an image from the inside of your body. It’s also known as sonography and is a painless procedure.

Ultrasound uses no radiation and for this reason, it’s the preferred method for viewing a developing fetus during pregnancy.

Why an ultrasound is performed?

An ultrasound allows your doctor to see problems with organs, vessels, joints, tendons, muscles and other tissues without needing to make an incision.

An ultrasound can provide a view of the:

  • Liver
  • Gall Bladder
  • Pancreas
  • Spleen
  • Kidneys
  • Urinary Bladder
  • Prostate
  • Uterus
  • Ovaries
  • Thyroid
  • Testicles
  • Blood Vessels
  • Brain (in infants)
  • Unborn child during pregnancy

An ultrasound is also a helpful way to guide the surgeons and radiologists movements during surgeries and certain medical procedures, such as biopsies and FNAC.

How to prepare for an ultrasound

Patients are advised to carry their doctor’s prescription and any relevant prior investigations when they come for the scan. A Government approved ID card of the patient/patients relative is mandatory for all pregnancy related ultrasounds along with their referring Doctor’s prescription.

It’s advisable to take a prior appointment.


Atleast 4-6 hours of fasting  but 8–10 hours of overnight fasting is preferable for gall bladder scans. You should also drink lots of water and hold your urine so that your bladder is full and better visualized.


You need to come on a full bladder . Empty stomach is not necessary.
If it is a transvaginal scan (TVS) you need to empty your bladder.


For pregnancy scans patient has to come on a full bladder if the pregnancy is less than 3 months. Fasting is not necessary for any pregnancy related scan.

A pregnancy scan may take anywhere between 10 minutes – 30 minutes. In certain cases the scan may have to be repeated at intervals especially if the fetus is not in the right position, It may rarely be necessary to be call you back on another day if the scan is suboptimal.


You need to come on a full bladder unless it’s a transvaginal scan.

How is an ultrasound is performed?

The Doctor (Radiologist) usually holds a transducer, a hand-held device, like a wand, which is placed on the patient’s skin. A water based gel is applied to the skin which helps transmit the sound waves. Depending on the area being examined, you may need to change positions. After the procedure is over, the gel will be cleaned off of your skin.

  • Would you like to see your unborn baby’s face before its birth? Now experience the miracle of watching your unborn baby in 4D HD LIVE realistic views.

    What is it?

    We understand how joyful it is to become a mother, therefore to make this delightful wait a little easier, we provide 4D HD LIVE ultrasounds, which allow you to watch your baby in 3D and move with realistic perspectives. This is an experience you will never forget. A 4D scan is a type of ultrasound imaging in which the baby can be seen moving in real time – like in a movie or film – as a result of adding the time dimension to a standard 3D ultrasound scan.

    When to get it done?

    It is recommended to perform a 4D scan between 24 to 32 weeks of pregnancy. It may get more difficult to view the baby’s face as your pregnancy progresses. For twins, 22-25 weeks is the ideal time to see the little ones.

    Why you should get it done?

    Many expecting parents use this optional session to strengthen their bond with their child or to introduce their child to their family members. We can capture your baby’s yawning and stretching motions.
    In most cases, 4D scans are not required for medical diagnosis. A 4D scan, on the other hand, could be useful if your child has a face issue like cleft palate or cleft lip.

    Apart from pregnancy scans we also offer transvaginal(TVS) 3D scans used for fibroid mapping and morphological anomalies in Uterus like Bicornuate/Septate uterus.
