| 摘要 |
A magnetic resonance imaging (MRI) system (600), for acquiring magnetic resonance (MR) information of a volume, includes at least one controller (610) configured generate at least a portion of a stimulated echo acquisition mode (STEAM) CEST-sequence including first through third 90° radio frequency (RF) pulses, and a first pulse train situated before the first 90° RF pulse. The first pulse train has first number of pulses. The controller (610) is further configured to generate at least another portion of the STEAM CEST sequence comprising a second pulse train situated between the second and third 90° RF pulses, the second pulse train comprising a second number of pulses which is less than the first number of pulses; generating end of spoil gradients; and/or to ac quire MR information during an acquisition window which is stated at least partially after the end of spoil gradients. |
