RESUMO
Objective To explore the value of multimodal magnetic resonance myocardial perfusion imaging (MR-MPI)in detecting myocardial viability of coronary heart disease.Methods 52 patients suspected or diagnosed coronary heart disease confirmed with SPECT myocardial perfusion and had MR-MPI examination were collected.MR-MPI protocol included double inversion T2WI fat suppressed imaging,diffusion weighted imaging(DWI),resting perfusion and dipyridamole myocardial perfusion.Results In 52 patients,the sensitivity,specificity,positive predictive value and negative predictive value of MR-MPI were 89.13%,66.67%,95.35% and 44.44% respectively.Conclusion MR-MPI can effectively detect myocardial viability in coronary heart disease.MR-MPI exhibits high clinical value for qualitative evaluation of degree of the myocardial ischemic coronary heart disease.
