Final answer:
ABI Doppler U/S Angiography (CTA or MRA) are diagnostic tests used in medicine to evaluate blood flow and circulation. ABI measures blood pressure in the legs, Doppler U/S uses sound waves to create images of blood vessels and flow, and Angiography visualizes blood vessels using contrast dye.
Step-by-step explanation:
ABI Doppler U/S Angiography (CTA or MRA) are all diagnostic tests used in medicine to evaluate the blood flow and circulation in different parts of the body. ABI (Ankle-Brachial Index) is a non-invasive test that measures the blood pressure in the legs to assess peripheral artery disease. Doppler U/S (Doppler Ultrasonography) is an imaging technique that uses sound waves to create images of blood vessels and blood flow. Angiography (CTA or MRA) involves injecting a contrast dye into the blood vessels to visualize and evaluate any blockages or abnormalities.
