Pooled Data from Viability Studies of Bax et al. (18) with Different Techniques to Predict Improvement in LVEF After Revascularization

Technique	No. of studies	% Sensitivity	% Specificity	% NPV	% PPV
¹⁸F-FDG PET	20	93	58	85	77
²⁰¹Tl imaging	33	87	55	81	64
^99mTc-labeled tracers	20	81	66	77	71
DSE	32	81	80	85	77

DSE = dobutamine stress echocardiography; NPV = negative predictive value; PPV = positive predictive value.
