What is an Ultrasound?

Ultrasonography, or ultrasound, is a safe, painless, and non-invasive test. It uses sound waves to create real-time images of the organs and tissues inside your body. Since it doesn't use radiation, it is safe for everyone, including pregnant women.

Why Do I Need an Ultrasound?

Your doctor may recommend an ultrasound to:

• Check organs like the liver, kidneys, gallbladder, and pancreas
• Monitor pregnancy (fetal development, due date, and possible issues)
• Evaluate blood flow (such as with Doppler ultrasound for the heart and vessels)
• Examine injuries to muscles, tendons, and joints
• Guide surgeries or biopsies (helps doctors be more accurate)
• Investigate lumps or pain (such as cysts or tumors)

Preparation for the Test

What you need to do before the test depends on the area being scanned:

• Abdomen/Pelvis: Fast for 6-8 hours (you can drink water).
• Bladder/Kidneys: Drink 4-5 glasses of water 1 hour before the test for a full bladder.
• Pregnancy or other areas: Usually no special preparation needed.

• Wear loose, comfortable clothing.
• Bring any previous ultrasound reports if available.

What to Expect During the Test

• You will lie on an exam table, and a gel will be applied to your skin.
• A handheld probe is moved over the area. It might feel like slight pressure, but it’s painless.
• You may hear swishing sounds if Doppler ultrasound is used to check blood flow.
• The test usually takes 15-30 minutes.
• Afterward, the gel is easy to wipe off.

How Long Will It Take?

Total visit time: 30-45 minutes

Actual scan time: 15-30 minutes

Results: Often available immediately or within 24 hours if more detailed analysis is needed.

After the Test

• No recovery needed – you can resume normal activities right away.
• If contrast is used, drink water to flush it out.
• Your doctor will review the results and discuss any next steps if needed.
