Differentiating normal living myocardial tissue, injured living myocardial tissue, and infarcted myocardial tissue in vivo using magnetic resonance imaging

摘要

By administering MR contrast agent such as Gd-DPTA, waiting for a predetermined period of time and then acquiring T1-weighted MR image data, infarcted myocardial tissue can be distinguished from injured myocardial tissue. An in vivo cine MR study is used to distinguish normal myocardial tissue from injured or infarcted myocardial tissue. As a result, it is possible to distinguish between normal, injured but living, and infarcted myocardium using MR imaging.
