What is the purpose of lower extremities arterial imaging?
The Lower Arterial Imaging test is an Ultrasound study of the arteries of the legs. This test helps to determine the severity of the peripheral arterial disease (PAD). The exact location of the plaque, as well as how much plaque is present (percent stenosis) can be identified.
Peripheral vascular disease affects a large portion of the general population, more so in patients with known cardiac disease. You may have talked to your physician about swelling, redness, pain or cramping you are experiencing when you walk or even while at rest. This pain, redness or swelling can occur in the calves, thighs and buttocks. This pain can be intermittent or constant, making it difficult for you to walk distances.
Who administers the test?
A registered vascular ultrasound technologist administers this test.
How long will the test take?
The total amount of time this test will take is approximately 1 hour.
How should I prepare for my test?
Nothing to eat or drink five (5) hours prior to the test.
What will I experience during the test?
Ultrasound equipment is used to image the arteries from the abdomen to the feet. Doppler is also used to listen to the blood flow through each leg and several measurements are taken to determine the amount of plaque in the arteries. This test is painless, but pressure will be applied to enable the technologist to get adequate images.
