- Ultrasound - a test that uses sound waves to visualize the inside of the body.
- Abdominal and pelvic CT scan - a type of X-ray that uses a computer to take pictures of the inside of the body.
- Intravenous pyelography (IVP) - a series of X-rays of the urinary system taken after injection of a dye.
