What Is a Mesenteric Artery Ultrasound?
A mesenteric artery ultrasound is a safe, non-invasive imaging examination that uses high-frequency sound waves and Doppler technology to evaluate blood flow through the major arteries supplying the intestines. This specialized vascular study assesses the celiac artery, superior mesenteric artery (SMA), and, when appropriate, the inferior mesenteric artery (IMA) to help identify narrowing (stenosis), blockages, or other abnormalities that may reduce blood flow to the digestive system.
​
Mesenteric artery ultrasound provides real-time images and measures blood flow velocities to help detect mesenteric arterial disease, a condition that can contribute to abdominal pain after eating, unintended weight loss, and other symptoms related to reduced intestinal blood supply.
​
Unlike CT angiography or conventional angiography, mesenteric artery ultrasound does not use radiation or contrast dye, making it a safe and effective first-line examination for many patients.
Why Is a Mesenteric Artery Ultrasound Performed?
A Mesenteric Artery Ultrasound is performed to evaluate the major arteries that supply blood to the intestines, including the celiac artery, superior mesenteric artery (SMA), and, when appropriate, the inferior mesenteric artery (IMA). This examination uses Doppler ultrasound to assess blood flow and detect narrowing or blockages within these arteries. It is a safe, noninvasive, and radiation-free examination that does not require contrast dye.
​
This examination is commonly performed to look for mesenteric artery stenosis (narrowing) or occlusion (blockage), which can reduce blood flow to the intestines. Reduced blood flow may cause symptoms such as abdominal pain after eating, unexplained weight loss, fear of eating due to pain, or other signs of chronic mesenteric ischemia.
​
A Mesenteric Artery Ultrasound may also be performed to evaluate patients with suspected vascular disease affecting the abdominal arteries, monitor known mesenteric artery disease, or assess blood flow after angioplasty, stent placement, or other vascular procedures. It can also help evaluate abnormal findings from a physical examination or another imaging study.
​
Because ultrasound provides real-time evaluation of blood flow, it allows the technologist to measure blood flow velocities and identify areas of significant narrowing that may require further evaluation or treatment.
​
As a safe, painless, and radiation-free examination, a Mesenteric Artery Ultrasound is often used as a first-line imaging study to evaluate the blood supply to the intestines and help guide diagnosis, treatment planning, and follow-up care.
Common Reasons to Schedule a Mesenteric Artery Ultrasound
A Mesenteric Artery Ultrasound is performed to evaluate the arteries that supply blood to the intestines and assess blood flow through the celiac artery, superior mesenteric artery (SMA), and, when appropriate, the inferior mesenteric artery (IMA). You may benefit from this examination if you have symptoms or medical conditions that suggest reduced blood flow to the intestines.

A Mesenteric Artery Ultrasound provides detailed, real-time images of the mesenteric arteries while evaluating blood flow with Doppler ultrasound. It is a safe, painless, and radiation-free examination that helps detect narrowing, blockages, and other abnormalities affecting the blood supply to the intestines, guiding appropriate diagnosis, treatment, and follow-up care.
What to Expect During Your Examination
A mesenteric artery ultrasound is a safe, non-invasive examination that typically takes 45–60 minutes to complete. Because the mesenteric arteries are located deep within the abdomen, the examination requires careful imaging from several angles to obtain the most accurate assessment of blood flow. After you arrive, a registered vascular sonographer will explain the procedure and answer any questions you may have.
​
During the examination, you will lie comfortably on an examination table while a small amount of warm ultrasound gel is applied to your abdomen. A handheld ultrasound transducer is gently moved over the skin to obtain detailed images of the arteries supplying your intestines, including the celiac artery and superior mesenteric artery.
​
To improve image quality, you may be asked to take a deep breath, briefly hold your breath, or change your position during portions of the examination. These simple instructions help the sonographer visualize the arteries more clearly and obtain the most accurate Doppler measurements.
​
The examination is painless and does not involve needles, injections, radiation, or contrast dye. Once the study is complete, the ultrasound gel will be removed, and you may immediately return to your normal daily activities.
How to Prepare for Your Mesenteric Artery Ultrasound
A Mesenteric Artery Ultrasound requires some preparation to help obtain the clearest possible images of the arteries supplying blood to your intestines. Following these instructions will help ensure your examination is completed accurately and efficiently.
​
Before Your Appointment
​
✓ Do not eat or drink for 8 hours before your examination. A small amount of water is allowed to take necessary medications unless instructed otherwise by your healthcare provider.
✓ Continue taking your prescribed medications unless your healthcare provider gives you different instructions.
✓ Avoid smoking, chewing tobacco, vaping, or using nicotine products for several hours before your appointment, as nicotine can affect blood flow and the accuracy of the examination.
✓ Wear comfortable, loose-fitting clothing. You may be asked to change into an examination gown.
✓ Bring any previous ultrasound, CT angiography (CTA), MR angiography (MRA), angiogram, or other vascular imaging reports related to your abdominal arteries if they were performed at another facility.
✓ Arrive 10–15 minutes early to complete any necessary paperwork before your examination.

A Mesenteric Artery Ultrasound is a safe, noninvasive, and radiation-free examination that does not require contrast dye or injections. Proper fasting helps reduce bowel gas, allowing for better visualization of the mesenteric arteries and improving the accuracy of your examination.
Frequently Asked Questions
Q: What is a mesenteric artery ultrasound?
A: A mesenteric artery ultrasound is a safe, non-invasive examination that uses ultrasound and Doppler technology to evaluate blood flow through the arteries that supply your intestines. It helps detect narrowing (stenosis), reduced blood flow, and other vascular conditions that may affect intestinal circulation.
​
​Q: Why would my healthcare provider order this examination?
A: Your healthcare provider may recommend a mesenteric artery ultrasound if you experience abdominal pain after eating, unexplained weight loss, or if mesenteric artery disease is suspected. It is also commonly used to monitor patients after mesenteric artery angioplasty or stent placement.​
​
Q: Is the examination painful?
A: No. The examination is painless and non-invasive. You may feel gentle pressure from the ultrasound transducer as the sonographer images your abdomen, but there are no needles, injections, or incisions involved.
​
​Q: How long does the examination take?
A: Most mesenteric artery ultrasound examinations take 45–60 minutes, depending on your anatomy and the complexity of the study.​
Â
Q: Do I need to fast before my appointment?
A: Yes. In most cases, you should not eat or drink for 6–8 hours before your examination. Fasting helps reduce bowel gas, allowing the sonographer to obtain the clearest possible images of your mesenteric arteries.
Â
​Q: Is there any radiation or contrast dye involved?
A: No. Mesenteric artery ultrasound uses sound waves—not radiation—and does not require contrast dye, making it a safe and effective way to evaluate blood flow to the intestines.
Â
​Q: When will I receive my results?
A: Your ultrasound images will be reviewed by a board-certified interpreting physician. A comprehensive diagnostic report will be generated promptly. If you were referred by a healthcare provider, your results will also be forwarded to their office for review and follow-up.
Â
​Q: Can I drive and return to my normal activities afterward?
A: Yes. Once your examination is complete, you may drive yourself home and resume your normal daily activities immediately.​
