ARDMS SPI Practice Test 2026 — Free ARDMS SPI Exam Prep Questions
The SPI exam tests the ultrasound physics and instrumentation that every ARDMS credential rests on, and sonography students and practitioners take it alongside a specialty exam. Our practice questions cover wave propagation, transducers, image optimization, Doppler and hemodynamics, and safety, with every calculation worked step by step.
Deep structures appear too dark. Following the ALARA principle, which adjustment should the sonographer try first to brighten the image?
