ACR-ASNR-SNIS-SPR Practice Parameter for the Performance of Magnetic Resonance Angiography (MRA) of the Head and Neck

This practice parameter was revised collaboratively by the American College of Radiology (ACR), the American Society of Neuroradiology (ASNR), the Society of NeuroInterventional Surgery (SNIS), and the Society for Pediatric Radiology (SPR).This practice parameter provides a consensus-based guide for the safe, effective performance and interpretation of MRA imaging in the head and neck for adults and children. METHODS: This parameter was revised according to the process described under the heading The Process for Developing ACR Practice Parameters and Technical Standards on the ACR website (https://www.acr.org/Clinical-Resources/Practice-Parameters-and-Technical-Standards) by the Committee on Practice Parameters - Neuroradiology of the ACR Commission on Neuroradiology, the Committee on Practice Parameters - Interventional and Cardiovascular Radiology of the ACR Commission on Interventional and Cardiovascular Radiology, and the Committee on Practice Parameters - Pediatric Radiology of the ACR Commission on Pediatric Radiology in collaboration with the ASNR, the SNIS, and the SPR.
