ARRT MRI Certification - Complete Guide

The ARRT MRI credential is a post-primary certification - meaning you must hold a primary ARRT credential first. Here's exactly how it works.

Key Fact: ARRT MRI is Post-Primary

Unlike ARMRIT, the ARRT MRI credential requires you to first hold a primary ARRT credential - most commonly Radiologic Technology (R). If you don't already have an ARRT primary credential, the ARMRIT pathway is likely better suited for you.

What is ARRT?

ARRT stands for the American Registry of Radiologic Technologists - the largest certification body for medical imaging professionals in the United States. ARRT credentials are widely recognized by employers, states, and regulatory bodies across the country.

ARRT offers certification in over 20 imaging disciplines. MRI is one of the post-primary specialties - meaning you layer it on top of your primary credential rather than pursuing it independently.

Eligibility Requirements

Hold a primary ARRT credential in Radiologic Technology (R), Nuclear Medicine (N), Radiation Therapy (T), or other approved primary disciplines. Check ARRT.org for the current approved primary pathways - these are updated periodically.

Complete ARRT-required MRI education. You must complete the didactic and clinical education requirements specified by ARRT. These include a defined number of supervised clinical hours. Verify current requirements at ARRT.org.

Meet ethics requirements. ARRT requires candidates to meet their ethics standards - criminal convictions may affect eligibility. Review ARRT's ethics review process before applying if applicable.
