Abstract
In a method and apparatus to generate MR images of an examination region containing tissue with a first Ttime and tissue with a second, significantly longer Ttime are contained, as series of pulse sequences is employed the following pulse sequences: an overview pulse sequence to generate MR overview images, a T-weighted pulse sequence to generate T-weighted MR images and a multiple contrast pulse sequence in which at least two groups of magnetic resonance signals are acquired. A first group of magnetic resonance signals is acquired after excitation of a magnetization in a first time period and at least one second group of magnetic resonance signals is acquired in a second time period after the first time period in which the tissue with the significantly longer Ttime delivers the significant signal contribution. An MR image is calculated based on a pixel-by-pixel difference of the absolute values from the magnetic resonance signals of the first group and the second group.
