Clinical Applications of CMR Techniques for Assessment of Regional Ventricular Function

摘要: Cardiovascular magnetic resonance (CMR) allows for a highly accurate description of segmental wall motion and quantitation contractile function. The excellent contrast between the endocardium blood pool improves measurement thickness, end-diastolic end-systolic volumes, left ventricular (LV) ejection fraction. Other noninvasive imaging modalities such as echocardiography assume uniform LV geometry when calculating these global parameters. Errors caused by assumptions are magnified shape is deformed, in dilated cardiomyopathy or after myocardial infarction (MI). Because CMR acquires images tomographic set planes, no regarding made. Not only does produce more measurements, but also regional function can be precisely quantitated. purpose this chapter to describe clinical applications techniques assessment right (RV)
