Abdominal Ultrasound

Doctors use abdominal ultrasound to help determine the cause of symptoms coming from the abdomen. A patient may have stomach or back pain, or a mass might have been detected at a doctor’s visit. A variety of disorders can be diagnosed by abdominal ultrasound such as:

• Kidney stones
• Gallstones
• Tumors, abscesses, and cysts
• Aneurysms
• Blood clots
• Blood vessel narrowing

Benefits

• Abdominal ultrasound is an inexpensive, fast, and non-invasive way to assess structures inside the abdomen. In many cases, this test helps doctors accurately detect the cause of abdominal symptoms, avoiding more complex testing or exploratory surgery.
• Ultrasound does not expose you to any ionizing radiation (X-rays).
• Unlike MRI, ultrasound can be used in patients with any type of metal in their body, including implantable medical devices.
• Ultrasound is very safe and has no side effects.
• There is no need to take contrast for ultrasound exams.
• Ultrasound can detect soft tissue abnormalities that cannot be visualized with X-ray exams.

Risks

• The use of diagnostic ultrasound has no known risks or harmful effects.

• Abdominal ultrasound is done in an ARA outpatient imaging center. The exam will take about 30 minutes and you will be in the imaging center for about an hour.
• You may be asked to change into a gown.
• You will be placed lying on your back on an exam table. You may have to change position during the exam. For kidney ultrasound, you may be positioned face down or on your side.
• A water-based gel will be placed on the area to be examined. The gel creates a sealed contact between your skin and the ultrasound probe. This eliminates any air pockets that may interfere with imaging. The probe will be moved around to capture images from different locations. The gel does not stain clothing.
• The technologist or radiologist performing the study may have to apply pressure with the probe to the body part being examined. If the area is tender, you may experience some discomfort.
• The gel is wiped off of your skin.
• You can return to your normal activities after the exam is over.

• For exams of the liver, gallbladder, spleen, and pancreas you may be asked to avoid fat in your diet the evening before the test. Also, you may be asked to avoid eating and drinking for 8-12 hours before the exam.
• For kidney ultrasound, you may be asked to drink 4-6 glasses of liquid an hour before the exam. You may also be asked to avoid food for 8-12 hours before the test.
• For aortic ultrasound, you may be asked to avoid eating and drinking for 8-12 hours before the exam.
• Wear comfortable, loose-fitting clothing for the exam.
