AbstractAbstract
[en] Cardiac magnetic resonance imaging (MRI) using fast imaging techniques has been developing quickly recently. Left ventricular function with pharmacological intervention can be evaluated using True fast imaging with steady-state precession (FISP) method. In addition, left ventricular diastolic function can be evaluated by retrospective gating with a high frame rate. Myocardial perfusion and viability can also be evaluated by first-pass imaging and delayed enhancement with Gd-DTPA. Data concerning myocardial ischemia, viability, and left ventricular function is now almost equivalent to that of myocardial SPECT and contrast echo. Additionally, coronary arterial narrowing and coronary vessel wall can be visualized with both the bright-blood and black-blood method. These methods are still currently in the research stage. The prognostic value of myocardial perfusion and ventricular function in ischemic heart disease should be established using large numbers of patients. Multi-center trials using cardiac MRI should be recommended for this purpose. Furthermore, detecting acute coronary syndrome in the emergency department can be performed with safety and accuracy. MR coronary angiography should be used not only for flow-limiting coronary stenosis but also the atherosclerotic wall region. This provides information that may predict cardiovascular risk, and facilitate further study of artherothrombosis, progression and response to therapy. It may also provide for the assessment of subclinical disease. (author)
