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

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.
