A segmented cine MR pulse sequence of the &ldquo;TrueFISP&rdquo;-type having a short repetition time TR is used to acquire MR data during a single breath hold. In the resulting cine images, the blood and the myocardium have distinctly different image contrasts.

Cardiac cine imaging with a short repetition time and high contrast between the blood and the myocardium

During acquisition of one frame of MR data, the phase-encoding gradient oscillates between a maximum phase-encoding gradient and a minimum phase-encoding gradient. Each oscillation includes a zero phase-encoding gradient.

Method of acquiring MR data especially for cardiac cine data sets

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.
