Which describes a non-invasive test used in patients with symptoms of PAD that measures the blood pressure in the upper and lower extremities at rest and after exercise?​
A) ​magnetic resonance angiography
B) ​radionucleotide imaging
C) ​positron emission tomography
D) ​ankle-brachial index
E) ​CT angiography

Quizplus · Accepted Answer

The ankle-brachial index (ABI) is a non-invasive test used in patients with symptoms of PAD to measure the blood pressure in the upper and lower extremities at rest and after exercise. It is a simple and inexpensive screening tool used for the diagnosis of PAD. Magnetic resonance angiography, radionucleotide imaging, positron emission tomography, and CT angiography are all imaging tests used for the diagnosis of PAD, but they are more invasive and involve the use of contrast agents and radiation.
