​Considering a career in sonography?

Sonography is one of the fastest growing healthcare fields, with demand for skilled and certified professionals increasing every year. As a student, pursuing an ARDMS certification will distinguish you as a prominent practitioner of sonography.

 What is Sonography?

​Sonography (ultrasound) is a non-invasive diagnostic medical imaging procedure that is used to visualize organs or systems in the body. It is commonly used to monitor fetal growth and understand the health of the heart, the abdomen and the vascular and musculoskeletal systems.

 What is an ARDMS number and how do I use it?

​When you apply for the SPI examination or create a MY ARDMS account, you will receive an ARDMS number. You will use this number to apply, and sit, for an ARDMS examination once you have met the prerequisite or eligibility requirements.


Note that your ARDMS number does not indicate that you are registered with ARDMS, are eligible to sit for an ARDMS exam or are credentialed. Inappropriate use of this number could result in your examination eligibility being revoked.
