Who should perform the annual testing of MRI units?

Annual testing of MRI units should be performed by a physicist due to their specialized training and expertise in the principles of imaging physics, safety, and performance evaluation of MRI systems. Physicists have a comprehensive understanding of the technical aspects involved in magnetic resonance imaging, including the intricate calibration requirements and the assessment of quality assurance metrics.

They are knowledgeable about the standards and regulations set forth by organizations such as the American College of Radiology (ACR) and the Radiological Society of North America (RSNA), which outline the necessary protocols for the operation and maintenance of MRI machines. This expertise is crucial in ensuring that the MRI equipment operates within safe and effective parameters and that it provides high-quality imaging for accurate diagnoses.

While other personnel involved in MRI operations, such as technologists or radiologists, have critical roles in patient care and image acquisition, they do not typically possess the specialized technical training required for the intricate quality assurance testing and risk management involved in MRI units.
