51Թ provides ARDMS classes to sonographers who are preparing to take either the Registered Diagnostic Medical Sonographer (RDMS) certification or the Sonography Principles and Instrumentation (SPI) exam. Taking either of these exams issued by the American Registry for Diagnostic Medical Sonography can be a boon to your career. With the help of your ARDMS prep course, you can learn more efficiently than if you were studying on your own.
Sonographers must first pass the SPI, which assesses basic knowledge of instrumentation and basic physical principles that are necessary for sonography students and those who work in the field. The ARDMS prep courses that 51Թ offers involve one-on-one study sessions with an instructor covering the content on the exam. The SPI exam content areas are listed below, along with the portion of the test that will focus on each one:
- Clinical Safety, Patient Care, and Quality Assurance - 10%
- Patient Care
- Quality Assurance
- New Technologies
- Physical Principles -15%
- Physical Principles
- Ultrasound Transducers -16%
- Transducers
- Imaging Principles and Instrumentation - 28%
- Instrumentation
- Doppler Imaging Concepts - 31%
- Hemodynamics
Our ARDMS course entitles you to personalized study sessions. If you're finding physical principles especially challenging, your ARDMS class instructor can take the time you need to gain a firm understanding of the concepts. Another way ARDMS courses can be customized to meet your needs is based on your instructor getting to know how you study most effectively and guiding you towards those practices that will help you learn most resourcefully.
More than just covering the content, you can take advantage of an ARDMS prep class that also provides test-taking strategies geared towards the specific test you're taking and your strengths in testing situations. For example, if you've been provided a timed practice test and you're having a hard time answering all the questions in the time allowed, your tutor could work with you on improving your pacing and using other techniques until you feel confident you can complete all the questions when the day of the exam arrives.
Another thing ARDMS prep classes can prepare you for is the structure of the exam. This is how the SPI exam breaks down:
Format | # Questions | Interface | Time Allowed |
Multiple-Choice | 110 | The Semi-Interactive Console simulates a live ultrasound machine and administers questions | 2 Hours |
Your instructor can also help you become familiar with the non-traditional interface.
Once you've earned your SPI certification, you have up to five years to successfully complete the RDMS certification. These credentials were developed to raise diagnostic medical ultrasound practices throughout the world. They also encourage sonographers to follow best practices, which enhance the safety of patients. Earning the RDMS credential shows that a professional in sonography has the critical knowledge and skills needed to promote public safety in ultrasound situations.
As you can see, the SPI exam and RDMS credentials are worth taking the time and making the effort to prepare for as thoroughly as possible. That's why 51Թ developed an ARDMS class for you that can so directly meet your unique set of needs, goals, and attributes. You don't have to rely on your own understanding of a passage in a test information booklet or wonder if the information on the website you're reading provides accurate information. You can be confident your instructor is providing you with accurate, relevant, and personalized study help.
