What is the prognostic value of gated myocardial perfusion SPECT? 
The prognostic value of gated myocardial perfusion SPECT has been evaluated in a study by Shaw and Iskandrian (115). They found that the test was able to predict coronary events with a high degree of accuracy. Specifically, they found that the sensitivity and specificity of the test was above 90%, and the positive and negative predictive values were above 70%. This indicates that gated myocardial perfusion SPECT is a valuable tool for predicting coronary events.
