Which diagnostic tool can measure the pressure in arteries for PAD assessment?

Segmental pressure measurements are specifically designed to assess vascular conditions such as peripheral artery disease (PAD) by measuring the blood pressure in various segments of the limbs. This technique involves the use of a Doppler ultrasound and a sphygmomanometer to obtain blood pressure readings at different levels of the legs or arms. By comparing these measurements, the technologist can identify significant differences in blood pressures between segments, indicative of narrowing or blockage in the arteries due to PAD.

Other diagnostic tools, while useful for vascular assessment and imaging, do not measure arterial pressure directly. Ultrasound imaging primarily provides information about the structure and blood flow within the vessels but does not quantify pressure. CT angiography and magnetic resonance angiography offer highly detailed images of blood vessels and can visualize blockages or anomalies, but they do not provide direct pressure measurements necessary for the functional assessment of PAD.
