Assessment of left ventricular (LV) function in patients with myocardial infarction (MI) provide useful diagnostic and prognostic information. Up to date, single photon emission tomography (SPET), positron emission tomography (PET), multidetector computed tomographic angiography, echocardiography (EC) and magnetic resonance imaging (MRI), have been used to examine LV parameters. However, due to limitations of some imaging methods, new studies are directed to improve myocardium function evaluation. In conclusion, SEC and GSPET can be applied to semi-quantitatively assess LVEF and regional wall motion abnormalities in a noninvasive manner. These techniques can provide strong diagnostic and prognostic information related to anterior myocardial infarction. In addition to this, nitrate enhanced GSPET allows to identify stunning and hibernating myocardium. New methods of reconstruction on GSPET systems will better improve image quality using lower count rates.
