Predictive accuracy of imaging tests for myocardial viability

Weighted mean positive and negative predictive accuracy of the different imaging tests for predicting recovery of segmental function after revascularization from a meta-analysis of 52 studies that included 1367 patients with ischemic left ventricular dysfunction. The rectangles are centered on the weighted means, and the size of the rectangles indicates 95 percent confidence intervals. The highest negative predictive values were seen with FDG-PET, reinjection thallium SPECT, and dobutamine echocardiography, while the highest positive predictive value was seen with dobutamine echocardiography.
