Abstract:
1. A method to generate magnetic resonance images of an examination region of a subject, said examination region comprising tissue exhibiting a first T 2 time and tissue exhibiting a second T 2 time that is substantially longer than said first T 2 time, said method comprising the steps of: with a magnetic resonance data acquisition unit in which the examination subject is located, radiating the subject with a series of pulse sequences; in said series of pulse sequences, initially radiating an overview pulse sequence from which magnetic resonance overview images are generated; after said overview pulse sequence in said series, radiating a T in said series, radiating a multiple contrast pulse sequence in which at least two groups of magnetic resonance signals are acquired, a first of said two groups being acquired after excitation of a magnetization in a first time period and at least a second of said two groups being acquired at a second time period after said first time period, in which said tissue with said substantially longer T in a processor, calculating a final magnetic resonance image as a pixel-by-pixel difference of respective absolute values of the magnetic resonance signals in said first of said groups and said second of said groups.
