|Prognostic value||Predictive of risk for cardiac events, supported by some studies (30,31,54,55). Less evidence to support PET when compared with SPECT.|
|Randomized trials||None available.|
|Suggestions for current clinical use|
|Potential future use||May be used as first-line test in all cases if diagnostic superiority to SPECT is confirmed in head-to-head or randomized trials and if cost-effectiveness is proven in the present health care environment.|
PET = positron emission tomography; SPECT = single-photon emission computed tomography.
