ACR-ASNR-SPR Practice Parameter for the Performance of Computed Tomography Angiography (CTA) of the Head and Neck.

AIM/OBJECTIVES/

BACKGROUND

This practice parameter was revised collaboratively by the American College of Radiology (ACR), the American Society of Neuroradiology (ASNR), and the Society for Pediatric Radiology (SPR). The practice parameter has been updated to reflect current performance of CT angiography of the head and neck with the inclusion of newly-available information since the last revision.

METHODS

This practice parameter was developed 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 and the Committee on Practice Parameters - Pediatric Radiology of the ACR Commission on Pediatric Radiology in collaboration with the ASNR, and the SPR.

RESULTS

CTA is a widely-used modality in neuroradiology, and is critically important for diagnosis and monitoring of numerous conditions. This updated practice parameter provides information on indications, patient preparation, equipment specifications, examination performance, and interpretation of head and neck CTA in current practice.

CONCLUSIONS

This practice parameter can be used to establish or modify a head and neck CTA protocol based on current evidence and recommendations.
