What is an ultrasound?
An ultrasound (USG) uses sound waves to create live images of organs and tissues inside the body. Dr. Chandak uses a handheld probe, moved gently over the skin with a small amount of gel, to see structures like the liver, kidneys, gallbladder, and more.
Why is an ultrasound done?
- To investigate abdominal pain
- To check the liver, kidneys, or gallbladder for stones or other issues
- To evaluate a lump, such as in the thyroid
- As part of a general health check-up
- For pregnancy scans (see our Fetal Medicine & Pregnancy Scan page)
How to prepare for an ultrasound
Preparation depends on which part of the body is being scanned:
- Abdominal scans: fasting for 6 to 8 hours beforehand, since food and gas can block the view
- Pelvic scans: a full bladder is often needed for a clearer image
The clinic will confirm which preparation applies to your specific scan when you book.
What happens during the scan
A small amount of gel is applied to the skin, and the probe is moved gently over the area being examined. The scan is painless and usually takes 15 to 30 minutes, depending on what is being checked.
What happens after the scan
The gel is wiped off and you can resume normal activity right away. There is no recovery time needed.
Is an ultrasound safe?
Yes. Ultrasound uses sound waves, not radiation, and is considered safe for adults, children, and during pregnancy.
Frequently asked questions
No. It is a painless test. You may feel slight pressure from the probe.
Fasting is usually required for abdominal scans but not for all types of ultrasound. The clinic will confirm this when you book.
Ultrasound uses sound waves and has no radiation, making it a good first choice for many conditions. CT and MRI use different technology and are used for specific situations your doctor will advise on.
Reports are usually ready the same day.
