Analyze blood flow in the arterial system of the arm, with particular attention to the influence of the radial arteries on blood flow to the hand.
No preparation is required.
Go to the reception desk of the imaging department, where you will put on a hospital gown.
Once in the exam room, you will be asked to lie down on your back. The medical imaging technologist starts by applying ultrasound gel, which is a water-based gel that conducts ultrasound waves through the skin, on the region that will be examined. Next, using an ultrasound probe (a small device that looks like a microphone), the technologist analyzes blood circulation at various areas.
The technologist will take a number of manual pressure readings from your wrist to analyze how your blood flow reacts to compressions.
The Doppler ultrasound can be noisy at times. The Doppler technique is used to listen to blood flow. It is therefore completely normal to hear various sounds throughout the exam.
The technologist finishes the exam by taking your blood pressure in both arms.
There are no side effects. After the exam, you may get dressed and leave. We will send the report from the exam to your doctor.
