Doppler ultrasound: What is it used for? - Mayo Clinic
What is a Doppler ultrasound? Doppler ultrasound is a noninvasive test that can be used to measure the blood flow through your blood vessels. It works by bouncing high-frequency sound waves off red blood cells that are circulating in the bloodstream. A regular ultrasound uses sound waves to produce images, but can't show blood flow.
Carotid ultrasound - Mayo Clinic
Carotid (kuh-ROT-id) ultrasound is a procedure that uses sound waves to look at blood flow through the carotid arteries. The carotid arteries are a pair of blood vessels on each side of the neck. They deliver blood from the heart to the brain. A carotid ultrasound also checks the thickness of the carotid artery wall and for blood clots.
Renal artery stenosis - Symptoms and causes - Mayo Clinic
Renal artery stenosis is when one or more arteries that carry blood to the kidneys narrow. These are called the renal arteries. Having narrowed renal arteries means the kidneys don't get enough oxygen-rich blood. The kidneys need enough blood flow to help filter waste products and remove excess fluids. Less blood flow to the kidneys may injure kidney tissue and raise blood pressure throughout ...
Median arcuate ligament syndrome (MALS) - Mayo Clinic
Overview Median arcuate ligament syndrome, also called MALS, happens when the band of tissue in the upper belly area presses on the artery that sends blood to the stomach, spleen and liver. This tissue is called the median arcuate ligament. The artery is called the celiac artery. The median arcuate ligament creates a pathway between the chest and belly area for the body's main blood vessel ...
Mitral valve regurgitation - Symptoms and causes - Mayo Clinic
Overview Mitral valve regurgitation is the most common type of heart valve disease. In this condition, the valve between the left heart chambers doesn't close fully. Blood leaks backward across the valve. If the leakage is severe, not enough blood moves through the heart or to the rest of the body. Mitral valve regurgitation can make you feel very tired or short of breath.

The images can help guide diagnosis and treatment for many diseases and conditions. Most ultrasounds are done using a device outside the body. However, some involve placing a small device inside the body.
Renal artery stenosis - Diagnosis and treatment - Mayo Clinic
Your healthcare professional might order the following imaging tests: Doppler ultrasound. High-frequency sound waves help a healthcare professional see the arteries and kidneys and check how they work. This procedure also helps find if the blood vessels are blocked and measure how bad the blockage is. CT scan. This is a type of imaging that uses X-ray techniques to make detailed images of the ...
Priapism - Diagnosis & treatment - Mayo Clinic
Ultrasound. You might have Doppler ultrasonography — a noninvasive test that can be used to estimate blood flow through blood vessels by bouncing high-frequency sound waves (ultrasound) off circulating red blood cells. This test can be used to measure blood flow within your penis that would suggest ischemic or nonischemic priapism.
Deep vein thrombosis (DVT) - Diagnosis & treatment - Mayo Clinic
There are three main goals to deep vein thrombosis (DVT) treatment. Prevent the clot from getting bigger. Prevent the clot from breaking loose and traveling to the lungs.

Blood thinners reduce the risk of developing more ...
Arteriosclerosis / atherosclerosis - Diagnosis and treatment - Mayo Clinic
Doppler ultrasound. A healthcare professional may use a special ultrasound device to check blood flow at different points in your body. The test results show the speed of blood flow in the arteries. This can reveal any narrowed areas. Ankle-brachial index (ABI). This test compares the blood pressure in the ankle with that in the arm.
