Many older patients undergoing an exercise stress test may not need molecular imaging to provide a clear picture of cardiovascular health. Evidence suggests that SPECT MPI may not provide any additional information for those who are nimble enough to reach a certain level of exertion and show no signs of CAD or cardiovascular distress. These and similar findings point to potential radioisotope injection guidelines to reduce radiation dose and cost of healthcare for these patients, according to research presented at the International Conference on Nuclear Cardiology and Cardiac CT, held May 5 to 8 in Berlin.
