PY - 2022 T2 - Nuclear Cardiology: Practical Applications, 4e AB - KEY POINTSRadiation exposure and outcomes: Radiationexposure to patients should be a concern in evaluating testing procedures.Current patient radiation exposure demonstrates 12 to 15 mSv for single-photon emission computed tomography (SPECT) and 3.5 to 4.0 for positron emission tomography (PET) perfusion imaging.Strategies for radiation reduction in SPECT MPI are described and include stress-only imaging and radiation reduction software applicable for most current cameras.Current status of PET radiation exposure demonstrates that the common tracer, rubidium, is consistently below the American Society of Nuclear Cardiology recommendations for patient exposure.Strategies for radiation reduction in PET MPI include 3D imaging and use of one transmission scan for attenuation correction.Can radiation reduction strategies work? Recent studies demonstrate success in meeting more than 5 mSv per patient with current systems.
