  1. To diagnose peripheral artery disease

  2. To evaluate venous insufficiency

  3. To detect deep vein thrombosis

  4. To treat varicose veins
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Peripheral angiography is primarily indicated for diagnosing peripheral artery disease, which is a narrowing of the arteries in the legs or arms.

Multiple choice

What is the primary indication for performing carotid angiography?

  1. To diagnose carotid artery disease

  2. To evaluate brain function

  3. To detect stroke

  4. To treat aneurysms
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Carotid angiography is primarily indicated for diagnosing carotid artery disease, which is a narrowing of the arteries that supply blood to the brain.

Multiple choice

Which imaging modality is commonly used in conjunction with angiography to provide detailed images of the heart?

  1. Ultrasound

  2. Magnetic resonance imaging (MRI)

  3. Computed tomography (CT)

  4. Positron emission tomography (PET)
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Magnetic resonance imaging (MRI) is commonly used in conjunction with angiography to provide detailed images of the heart, as it can generate cross-sectional images of the heart and its structures.
