Imaging techniques such as echocardiography, ventriculography, and nuclear imaging can be used to detect a contractile dysfunction following reperfusion after an episode of ischemia. The area of dysfunction should also maintain normal perfusion, detected via Positron Emission Tomography, echocardiography with contrast, and/or thallium scintigraphy in order for a diagnosis of<unk>  to be considered. However, there are many practical challenges to diagnosing<unk>  using these methods. Accurate detection of regional myocardial blood flow and contraction function abnormalities must be detected at levels of high sensitivity. The diagnosis of<unk>  must also be differentiated from other conditions such as hibernating myocardium and persistent (silent) subendocardial ischemia, which can also co-exist with superimposed<unk> .
