Vascular studies are a group of diagnostic tests that evaluate the blood vessels and circulation system of the body. These tests can help diagnose various vascular conditions, including peripheral artery disease, deep vein thrombosis, and aneurysms.
There are several types of vascular studies, including:
- Doppler ultrasound: This test uses high-frequency sound waves to create images of blood flow through the arteries and veins.
- Magnetic resonance angiography (MRA): This is a non-invasive imaging test that uses a powerful magnetic field and radio waves to create detailed images of blood vessels.
- Computed tomography angiography (CTA): This is a non-invasive test that uses X-rays and computer technology to create detailed images of blood vessels.
- Digital subtraction angiography (DSA): This test involves the injection of a contrast material into the blood vessels to create detailed X-ray images of blood flow through the arteries and veins.
- Ankle-brachial index (ABI): This test measures the blood pressure in the ankle and arm to determine the presence of peripheral artery disease.
- Venous duplex ultrasound: This test uses high-frequency sound waves to create images of blood flow through the veins, helping to diagnose deep vein thrombosis.
Your doctor may recommend one or more of these tests based on your symptoms and medical history. It's essential to discuss any concerns or questions you have about these tests with your healthcare provider.
