Ultrasound uses sound waves and a computer to generate focused images of the body. It does not use x-rays, a form of ionizing radiation, to acquire the images. Thus it is safer for the patient and non-invasive. Ultrasound exams are available on an inpatient and outpatient basis.
Ultrasound is frequently used to evaluate the abdomen, including:
- Liver disease
- Splenic masses
- Gastrointestinal tract – e.g. Foreign body obstruction, tumors
- Urinary bladder – e.g. Stones
- Kidney disease
Ultrasound can also be used to evaluate other parts of the body including the chest, tendons, and salivary glands, and to guide biopsies or needle aspirates.
