Ultrasound imaging uses high-frequency sound waves to view inside the body. It is a safe and painless procedure often used during pregnancy and to diagnose various medical conditions.

How to Prepare

• Fasting: For abdominal ultrasounds, you may need to fast for several hours before the exam.
• Full Bladder: For pelvic ultrasounds, you may be asked to drink plenty of water to ensure a full bladder, which helps create clearer images.
• Comfortable Clothing: Wear loose, comfortable clothing, as you may need to change into a gown.

Following your doctors instructions will help ensure accurate results.
