The application of phase analysis of gated myocardial perfusion imaging to assess left ventricular mechanical dyssynchrony in cardiovascular disease

Left ventricular mechanical dyssynchrony is closely related to the severity of cardiovascular disease, it is essential to assess left ventricular mechanical dyssynchrony accurately for early prediction of adverse cardiac events and prognosis assessment of the cardiac resynchronization therapy. As a new technology to assess left ventricular mechanical dyssynchrony, the phase analysis of gated myocardial perfusion imaging(GMPI) can get both quantitative indicators of regional myocardial perfusion, evaluation of regional myocardial viability and scar tissue, as well as quantitative analysis of left ventricular function and left ventricular mechanical synchrony, it has broad application prospects in cardiovascular disease to assess left ventricular mechanical dyssynchrony and prognosis assessment. This review mainly described the applications of GMPI phase analysis in the cardiovascular disease.
