Ultrasound Preparation Guidelines

Ultrasound: How to prepare for the examination

Ultrasound (US) is one of the most popular and safest diagnostic methods, providing accurate images of internal organs, tissues, and blood vessels. The method is based on the use of ultrasound waves, which are completely harmless to the body. This makes the procedure suitable for patients of all ages, including children and pregnant women.

What can be diagnosed with ultrasound?

Ultrasound is used in various fields of medicine to diagnose a wide range of conditions:

• Abdominal cavity. Helps detect inflammatory processes in the liver, gallbladder, pancreas, and spleen. It can reveal stones, tumors, and other pathologies.

• Urinary system. Examination of the kidneys, bladder, and ureters can detect kidney stones, cysts, and inflammation.

• Thyroid gland. Detects nodules, tumors, changes in tissue structure, and evaluates gland size.

• Cardiovascular system. Echocardiography and Doppler ultrasound help diagnose heart defects and assess vessel condition and blood flow.

• Breast tissue. Detects cysts, tumors, and inflammation at early stages.

• Soft tissues. Identifies injuries, inflammation, and tumors in muscles and subcutaneous tissue.

How is the procedure performed?

The examination is carried out in comfortable conditions and usually takes no more than 30 minutes. The doctor applies a special gel to the examination area to improve sensor contact with the skin. The sensor sends ultrasound waves, which are displayed as images of the organs on the monitor.

Preparation for ultrasound

Proper preparation is important for accurate results:

• Abdominal ultrasound. Fasting for 8–12 hours before the exam is required. Avoid gas-producing foods 1–2 days before.

• Bladder ultrasound. Drink 1–1.5 liters of water 1–2 hours before the exam and do not urinate to ensure better visualization.

• General advice. Your doctor may provide additional preparation instructions depending on the type of exam. Inform them about any medications or chronic conditions. 

• Pelvic ultrasound. For transabdominal exams, preparation is similar to bladder ultrasound — drink water and avoid urination before the procedure.

• Thyroid ultrasound. Minimal preparation — avoid heavy meals 2–3 hours before to prevent pressure on the neck area.

If you have previous ultrasound results, bring them with you to help track changes over time.
