PS vs SPI: ARDMS Exam Comparison

Compare the ARDMS Pediatric Sonography (PS) and SPI Physics (SPI) exams side by side: pass rates, difficulty, content domains, career paths, and study strategies.

Ultrasound Analytics is an AI-powered study platform built specifically for the seven ARDMS specialty registrations: Abdomen (AB), Breast (BR), Fetal Echocardiography (FE), Obstetrics and Gynecology (OB), Pediatric Sonography (PS), Vascular Technology (VT), and Sonography Principles and Instrumentation (SPI). Every page on the site is mapped to the official ARDMS content outline so your study time translates directly into the same domain-level performance the registry actually scores.

Our practice-quiz mode delivers 25, 50, or 100 board-style multiple choice questions per session with immediate AI tutoring after every answer, while exam mode runs the full 170-question timed simulation that mirrors the real ARDMS examination. The AI tutor, powered by Anthropic Claude Sonnet, explains the correct answer, defines why each wrong answer is wrong, and offers follow-up questions that target the exact concept you missed.

The analytics dashboard computes an exam-specific Readiness Score and Estimated Pass Probability for each specialty using official ARDMS domain weights, with hard caps that keep the projection honest when accuracy is weak or coverage is thin. The AI Sonography Assistant adds personalized study guides, customized topic guides, clinical-grade exam protocols, AI-generated image quizzes, and structured reports from uploaded ultrasound images.

Educational institutions can onboard students in bulk, monitor cohort readiness with the same Readiness Score that students see, and identify at-risk learners early.
