RVT ARDMS EXAM FINAL SCRIPT 2026
COMPLETE SOLUTION SET
◉ Distal to a stenosis, PI (increases/decreases) and AT
(increases/decreases). Answer: PI decreases, AT increases
◉ A 2x increase of PSV at a stenosis = _____% stenosis Answer: 50%
◉ A 4x increase of PSV at a stenosis = ______% stenosis Answer: 75%
◉ How is the damping factor calculated? Answer: PI prox to
stenosis/ PI dist to stenosis
◉ The greater the stenosis, the (greater, lesser) the damping factor
Answer: Greater
◉ At the CFA, an AT > ______ indicates inflow disease. Answer: 140 ms
◉ In a segmental pressure exam, if the cuff is too wide the pressure
will be (under/over)estimated. Answer: Underestimated
,◉ In a segmental pressure exam, a > _______ mmHg difference
between two adjacent levels in the same leg is abnormal. Answer: >
30 mmHg
◉ In a segmental pressure exam, a > _______ mmHg difference
between the same level on the opposite leg is abnormal. Answer: >
20 mmHg
◉ A >________ reduction in ABI on serial exams indicates disease
progression. Answer: > 0.15
◉ What does an ABI of 1.0 -1.3 indicate? Answer: Normal
◉ What does an ABI of 0.5 - 0.9 indicate? Answer: Mild to moderate
disease
◉ What does an ABI of <0.5 indicate? Answer: Severe disease
◉ What does an ABI > 1.3 typically indicate? Answer: Medial
calcification
◉ In a patient with true claudication, ankle pressures will
(drop/rise) with exercise. Answer: Drop
, ◉ What does it indicate if severe disease is seen with Doppler but
exercise has no effect on ankle pressures? Answer: Collaterals are
present
◉ Are PVR measurements affected by medial calcification? Answer:
No
◉ In a PVR exam, the loss of the dicrotic notch indicates ______
Answer: mild disease
◉ What disease seen in the pediatric population causes the
dilatation and potential aneurysm of small to medium arteries
(usually coronary arteries)? Answer: Kawasaki disease
◉ What lifestyle choice is Buerger disease always associated with?
Answer: Heavy smoking
◉ What is the most common location of Giant Cell Arteritis? Answer:
Superficial Temporal Artery
◉ What condition is associated with the Halo sign? Answer: Arteritis
◉ Are popliteal aneurysms usually unilateral or bilateral? Answer:
Bilateral
