Summit Planned on Managing CT Doses

A joint summit on optimizing image quality and managing CT radiation will be held in April, following several reports on the dangers of radiation therapy. The summit is organized by the American Association of Physicists in Medicine and funded by the American College of Radiology (ACR) and other groups.

Late last year, the FDA issued a safety investigation of CT brain perfusion scans after a radiation overexposure at Cedars-Sinai Medical Center in Los Angeles. And in January, a series of New York Times articles reported on radiation therapy accidents.

“Ideally, each CT scan protocal would be designed to meet the image quality need for the examination to be conducted on each patient, using the appropriate dose level, the ACR and the American Society of Neuroradiology (ASNR) said last fall in a joint statement calling for the summit. The process for establishing such a protocol has been difficult because various CT scanner manufacturers have different implementations, the statement said.

Organizers say the summit will enable participants to:

  • identify the trade-offs between CT image quality and dose associated with common scan and reconstruction parameters
  • recognize common technical and clinical errors in CT imaging
  • appreciate the characteristics of high-quality head, body, and cardiovascular CT scans
  • become familiar with multiple dose reduction strategies, including patient size adaptation
  • understand the roles and responsibilities of the various members of the imaging community for CT protocol development and optimization
