The multi-pronged approach to reducing MPI dose

April 30, 2015

The use of myocardial perfusion imaging (MPI) has spiked over the past four decades and along with it individual patient dose. A comprehensive effort to reduce that dose could reduce unnecessary procedures and reduce the risk of downstream cancers, according to a meta-analysis published in the April issue of the Journal of Nuclear Medicine.

With increasing procedure numbers came an estimated 10-fold increase in nuclear cardiology-related radiation exposure spanning from the early 1980s until 2006. In response, industry leaders have spurred multiple initiatives focused on appropriate-use criteria and technological development to reduce radiation dose.
