GI-Tl SPECT may enhance viability assessment in ischemic LV dysfunction; leaves open need for prospective validation before practice change.
Does glucose-insulin-thallium-201 infusion SPECT improve the prediction of reversible dysfunction compared to reinjection imaging and dobutamine echocardiography in patients with ischemic left ventricular dysfunction?
Glucose-insulin-thallium-201 infusion SPECT provides superior diagnostic accuracy compared to conventional reinjection imaging and low-dose dobutamine echocardiography for predicting functional recovery in ischemic left ventricular dysfunction.
