Increased MPI volumes heighten radiation exposure concerns; leaves open optimal implementation of dose-reduction strategies.
Cardiovascular diseases (CVDs) are the leading cause of death in Europe (5 million deaths per year) at a cost of e196 billion in 2009. Imaging techniques such as computed tomography (CT), single photon emission computed tomography (SPECT), and positron emission tomography (PET) play an increasingly important role in the diagnosis of CVD. Regarding myocardial perfusion imaging, scan volume has grown rapidly worldwide over the past two decades to 15–20 million procedures annually and diffusion of technology and expertise has led to its continued adoption across the developing world.2 However, there are concerns regarding the radiation burden associated with these diagnostic modalities.
