What Is an Upper Extremity Arterial Ultrasound?
An upper extremity arterial ultrasound is a safe, painless, and non-invasive imaging examination that uses high-frequency sound waves to evaluate blood flow through the arteries of the arms. These arteries carry oxygen-rich blood from the heart to the shoulders, arms, forearms, and hands. The examination helps assess circulation and identify conditions that may reduce blood flow, such as narrowing (stenosis), plaque buildup (atherosclerosis), arterial blockages, or other vascular abnormalities.
​
Using real-time ultrasound imaging and Doppler technology, your healthcare provider can evaluate the structure of the arteries, measure blood flow, and detect abnormalities without the use of radiation. An upper extremity arterial ultrasound is commonly performed to investigate symptoms such as arm pain, weakness, numbness, coldness, or discoloration of the hands and fingers. It is also used to diagnose and monitor arterial disease, evaluate circulation after vascular procedures, and assess patients with suspected thoracic outlet syndrome or other conditions affecting blood flow to the upper extremities.
​
This examination provides valuable information that helps your healthcare provider diagnose vascular conditions and determine the most appropriate treatment or follow-up care.
Why Is an Upper Extremity Arterial Ultrasound Performed?
An Upper Extremity Arterial Ultrasound is performed to evaluate the arteries of the arm and assess blood flow from the shoulder to the hand. This examination provides detailed, real-time images of the arteries while measuring blood flow without the use of radiation, contrast dye, or invasive procedures.
​
This examination is commonly performed to investigate symptoms that may suggest reduced blood flow to the arm or hand, such as pain, numbness, tingling, weakness, coldness, color changes, or fatigue during activity. It can help identify arterial narrowing (stenosis), blockage (occlusion), aneurysms, pseudoaneurysms, and other conditions affecting the arteries.
​
An Upper Extremity Arterial Ultrasound is also used to evaluate circulation following arm trauma, vascular surgery, or other procedures involving the arteries. It may be performed to assess abnormal pulses, monitor previously diagnosed arterial disease, or evaluate abnormal findings from a physical examination or another imaging study.
​
Because ultrasound provides real-time imaging, it allows the technologist to evaluate both the structure of the arteries and the direction and speed of blood flow using Doppler ultrasound. This helps accurately identify abnormalities and determine the severity of arterial disease.
​
As a safe, painless, and radiation-free examination, an Upper Extremity Arterial Ultrasound is often the preferred first-line imaging study for evaluating arterial circulation in the arms and helping guide diagnosis, treatment, and follow-up care.
Common Reasons to Schedule an Upper Extremity Arterial Ultrasound
An Upper Extremity Arterial Ultrasound is performed to evaluate the arteries of the arm and assess blood flow from the shoulder to the hand. You may benefit from this examination if you are experiencing symptoms of poor circulation, have known arterial disease, or require follow-up of a vascular condition.

-
Suspected peripheral arterial disease (PAD)
-
Decreased or absent pulse in the arm or wrist
-
Suspected arterial narrowing (stenosis) or blockage (occlusion)
-
Suspected aneurysm or pseudoaneurysm
-
Follow-up after arm trauma or arterial injury
-
Evaluation after vascular surgery or arterial intervention
-
Monitoring a previously diagnosed arterial condition

Assessment before or after vascular procedures involving the upper extremity
Â
An Upper Extremity Arterial Ultrasound provides detailed, real-time images of the arteries while evaluating blood flow with Doppler ultrasound. It is a safe, painless, and radiation-free examination that helps detect arterial narrowing, blockages, aneurysms, and other circulation problems, guiding appropriate diagnosis, treatment, and follow-up care.
What to Expect During Your Examination
An upper extremity arterial ultrasound is a comfortable, non-invasive examination that typically takes 30–60 minutes to complete, depending on whether one or both arms are being evaluated. 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 arm. A handheld ultrasound transducer is gently moved over the skin to obtain detailed images of the arteries and evaluate blood flow throughout the arm.
​
The sonographer will examine multiple arteries from the shoulder to the wrist, using Doppler ultrasound to assess blood flow and identify any areas of narrowing or blockage. Depending on the reason for your examination, you may be asked to change the position of your arm or perform simple movements to help evaluate circulation and obtain the best possible images.
​
The examination is painless and does not involve needles, injections, or radiation. 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 Upper Extremity Arterial Ultrasound
An Upper Extremity Arterial Ultrasound requires very little preparation. Following these simple instructions will help ensure your examination is completed comfortably and efficiently.
​
Before Your Appointment
​
✓ No fasting is required. You may eat and drink normally before your examination.
✓ Continue taking your usual medications unless instructed otherwise by your healthcare provider.
✓ Wear a loose-fitting or short-sleeved shirt that allows easy access to the arm, shoulder, and wrist being examined.
✓ Avoid wearing jewelry, watches, or tight-fitting clothing on the arm being evaluated, if possible.
✓ If you have had previous vascular surgery, arterial stents, bypass grafts, or other procedures involving your arm, let the technologist know before your examination.
✓ Bring any previous ultrasound, CT angiography (CTA), MR angiography (MRA), angiogram, or other vascular imaging reports related to your arteries if they were performed at another facility.
✓ Arrive 10–15 minutes early to complete any necessary paperwork before your examination.
​
An Upper Extremity Arterial Ultrasound requires no injections, contrast dye, radiation, or special preparation, making it a simple, safe, and convenient examination. Following these instructions will help ensure your examination is performed as comfortably and efficiently as possible.
Frequently Asked Questions
Q: What is an upper extremity arterial ultrasound?
A: An upper extremity arterial ultrasound is a safe, non-invasive imaging examination that uses high-frequency sound waves and Dopplertechnology to evaluate blood flow through the arteries of the arms. It helps detect narrowing (stenosis), blockages, and other circulation problems without the use of radiation.
Â
Q: Why would my healthcare provider order this examination?
A: Your healthcare provider may recommend an upper extremity arterial ultrasound if you have symptoms such as arm pain, cramping, numbness, tingling, cold hands or fingers, changes in skin color, or decreased circulation. It is also used to evaluate peripheral arterial disease (PAD), thoracic outlet syndrome (TOS), and to monitor vascular procedures such as bypass grafts or arterial stents.​
Â
Q: Is the examination painful?
A: No. The examination is painless and non-invasive. You may feel slight pressure from the ultrasound transducer, but there are no needles, injections, or incisions involved.​
Â
Q: How long does the examination take?
A: Most upper extremity arterial ultrasound examinations take 30–60 minutes, depending on whether one or both arms are being evaluated and the reason for the study.​
Â
Q: Do I need to fast before my appointment?
A: No. There are typically no dietary restrictions, and you may eat and drink normally unless your healthcare provider gives you different instructions.​
Â
Q: Is there any radiation involved?
A: No. Ultrasound uses sound waves—not radiation—making it a safe imaging method for evaluating blood flow in the arteries.
Â
​Q: When will I receive my results?
A: Your ultrasound images will be reviewed by a board-certified interpreting physician. A report will then be sent to your referring healthcare provider, who will discuss the results with you and recommend any necessary follow-up.​
Â
