What should you know?
Water is allowed before many ultrasound examinations and is often required before transabdominal pelvic or bladder ultrasound. For an upper abdominal examination, drink larger amounts only if the clinic specifically instructs you to.
Ultrasound uses high-frequency sound waves and does not use ionizing radiation. Preparation and examination time depend on the body area and the clinical question.
Common symptoms and signs
- Water is commonly taken about one hour before a full-bladder scan
- Carbonated or sweet drinks are not a substitute
- Transvaginal ultrasound is usually performed with an empty bladder
- Fluid intake should be individualized in severe heart or kidney disease
Diagnosis and the role of ultrasound
The radiologist selects the appropriate approach, examines the target structures in several planes, records measurements and uses Doppler when needed. Findings must be interpreted with symptoms and other clinical information.
- Organ size, shape and position
- Tissue texture and echogenicity
- Focal or diffuse changes
- Blood flow with Doppler when indicated
Ultrasound findings must be interpreted together with symptoms, examination and, when needed, laboratory or other imaging results. An image alone should not be used for self-diagnosis or self-treatment.
Treatment and next steps
When several areas are examined together, follow the exact combined preparation instructions provided by the clinic. Confirm preparation instructions with the clinic and do not stop essential medication unless your clinician tells you to.
Management is individual and depends on age, symptoms, imaging findings, other health conditions and pregnancy plans. Medication or a procedure should be selected with the appropriate clinician.
When is urgent care needed?
- Sudden severe or rapidly worsening pain
- Fainting, marked weakness or breathing difficulty
- Heavy bleeding, high fever or persistent vomiting
