【正文】 ength of the techniques are that they are the only monly available direct methods of assessing viability, although the relatively low resolution of the images disadvantages them for detecting small areas of infarction. Radionuclide Imaging ? The mon single photonemitting radiopharmaceuticals are also tracers of myocardial perfusion and so the techniques readily detect areas of infarction and inducible perfusion abnormalities. ? ECGgated imaging provides a reliable assessment of myocardial motion, thickening, and global function. Magic Resonance Imaging ? Cardiovascular MRI has high spatial resolution and moderate temporal resolution. It is a wellvalidated standard for the assessment of myocardial function and has, in theory, similar capability to echocardiography in suspected acute infarction. It is, however, more cumbersome in an acute setting and is not monly used. Magic Resonance Imaging ? Pa
