The Registered Musculoskeletal (RMSK) Registry Review online course is designed to prepare the physician and clinician to successfully take the APCA RMSK sonography certification exam. 

Upper and lower extremity joints are covered in great detail, including anatomy/physiology, scan protocols and normal sonographic characteristics, pathology, integration of data and treatment/interventional techniques. The APCA RMSK content outline indicates that 26% of the exam pertains to ultrasound physics so this online course includes a comprehensive review of Sonography Principles & Instrumentation (Physics). Post-module quizzes and two mock exams allow for assessment of comprehension of the material. 

This online course is the ideal choice for examination preparation, plus reinforcement of interpretation skills to improve competence and confidence to perform and/or interpret MSK ultrasound examinations.  

ULTRA P.A.S.S. Musculoskeletal Ultrasound Interactive Registry Review Online Mock Exam (compatible with Mac & PC) is an excellent self-assessment tool for the physician or clinician preparing to take the APCA RMSK sonography certification exam. 

The ULTRA P.A.S.S. Musculoskeletal Ultrasound Interactive Registry Review Online Mock Exam includes 277 questions that are based on the current APCA RMSK examination content outline and presented in a similar format as the exam. The mock exam includes both an exam mode and a study mode. In the Exam Mode, you will be able to demonstrate your subject knowledge in a timed setting mirroring the actual registry setting. Questions and answers are randomized each time the quiz is taken. The Study mode is an untimed exam format that provides feedback regarding the correct answer along with an explanation and reference to enhance the learning experience. 

IMPORTANT UPDATE: The APCA has updated their RMSK Exam Content Outline to include up to 26% ultrasound physics content. This product contains 50 Physics related questions. Please see our Sonography Principles & Instrumentation Online Mock Exam or the Sonography Principles and Instrumentation Registry Review Online Course for an entire comprehensive review for this topic.

Fully revised and updated, the 4th edition of Fundamentals of Musculoskeletal Ultrasound delivers a definitive, clinically focused guide to MSK ultrasound imaging. This bestselling resource provides a thorough, protocol-driven approach to scanning every major joint, empowering readers to build an efficient, systematic, and reproducible examination technique.

Each chapter pairs clear, step-by-step scanning protocols with high-quality illustrations and real-world ultrasound examples. Readers will see exactly where to place the transducer and how normal anatomy should appear, reinforcing spatial understanding and diagnostic confidence. Essential musculoskeletal anatomy is clearly reviewed and visually mapped to ultrasound findings, while common pathologic conditions are explored with corresponding imaging examples and integrated video content.
