发明名称 MAGNETIC RESONANCE METHOD AND APPARATUS WITH NUCLEAR SPINS TYPE-SPECIFIC SIGNAL SUPPRESSION
摘要 A method in the form of a sequence for magnetic resonance imaging with which image data of a subject to be examined are acquired and with which signals of nuclear spins of a specific type are suppressed, includes the steps of (a) application of a suppression module to suppress signals of the nuclear spins of the specific type, (b) application of an acquisition module after a wait time to acquire measurement data, (c) repetition of the steps (a) and (b) one or more times, respectively after a repetition time and, (d) before the steps (a), (b) and (c), application of a spin preparation module that shifts a magnetization of the nuclear spins of the specific type into a steady state condition that is maintained through the application of the subsequent steps (a), (b) and (c). Alternatively, instead of the spin preparation module the first suppression module can be fashioned such that it has an RF pulse with a flip angle selected such that the magnetization of the nuclear spins of the specific type is shifted into a steady state condition.
