Associations call for nuclear cardiology field to optimize radiation dose

November 21, 2016

New research reveals that the nuclear imaging field fails to consistently adhere to clinical guidelines to reduce patient radiation exposure, and many associations aren't happy about it.

The American Society of Nuclear Cardiology, the Intersocietal Accreditation Commission's Nuclear/PET accreditation division and the Society of Nuclear Medicine in Molecular Imaging are mandating that radiation dose be optimized for nuclear cardiology studies.

ASNC published guidelines for myocardial perfusion SPECT imaging in February 2016 and it listed recommendations on radiopharmaceutical activities and the appropriate radiation doses.

The dose reduction strategies included weight-based radiotracer dosing, thoughtfully selecting the radiotracers, performing stress-only imaging when appropriate, software innovations, purchasing advanced SPECT systems and using PET for myocardial perfusion imaging.
