Free ARDMS SPI Practice Test
The Sonography Principles & Instrumentation (SPI) exam from ARDMS tests ultrasound physics and instrumentation. Most sonography specialty credentials require passing SPI plus a specialty exam (e.g., ABD, OB/GYN).
Official-source aligned. Topic weights, timing, and pass rules follow published American Registry for Diagnostic Medical Sonography (ARDMS) outlines. Questions are original UniPrep2Go study aids — not leaked official items. Verify on the official site ↗

Sample ARDMS SPI practice questions
These sample items mirror the domains in the timed ARDMS SPI mock. Correct answers and explanations unlock inside the practice session.
Sample 1
On the ARDMS SPI, which bioeffect is more associated with cavitation risk? Select the best answer.
- A. Only skin burns from the keyboard
- B. Mechanical/nonthermal effects monitored conceptually by MI
- C. Solely the thermal index for bone
- D. MRI projectile risk
Sample 2
Increasing imaging depth while keeping other factors constant typically requires:
- A. Higher PRF
- B. Lower PRF to allow time for echoes to return
- C. Shorter listening time
- D. Elimination of the range equation
Sample 3
Bernoulli equation simplified in echo estimates pressure gradients from:
- A. 4v^2 (modified Bernoulli)
- B. v/4 only
- C. 2v
- D. PRF × depth
Sample 4
A convex (curved) array produces an image that is typically
- A. this concept always eliminates all investment, legal, and regulatory risk for every customer
- B. Blunted-sector shaped with a wider field at depth from sequential firing along a curved face
- C. this concept has no application in US securities, insurance, or licensing markets
- D. this concept is identical to FDIC deposit insurance for every customer account
Sample 5
Attenuation in soft tissue increases when:
- A. Frequency decreases with path fixed always reducing attenuation
- B. You freeze the image
- C. Path length or frequency increases
- D. Gain is increased (true attenuation change)
