Chest pain patients do well after ultralow-dose SPECT

April 10, 2015

Patients with chest pain who underwent SPECT myocardial perfusion imaging (MPI) with an ultralow-radiation-dose gamma camera had no major cardiac events a year later. The research, published in the April issue of the Journal of Nuclear Medicine, indicates that MPI radiation dose can be slashed without adverse clinical impact.

Researchers from Columbia University Medical Center and NewYork-Presbyterian Hospital in New York City found that a majority of patients who were scanned with the low-dose system had no major adverse cardiac events, did not have to return to the hospital for chest pains, and required no follow-up imaging or stress testing within three months of their emergency department visit. In addition, all 100 patients in the study remained free of any acute coronary symptoms one year later.
