    • The present invention provides a method for magnetic resonance (MR) imaging of a subject of interest (120) using arterial spin labeling, comprising the steps of performing a labeling module (200) by applying magnetic and/or radio frequency (RF) fields to the subject of interest (120) for labeling arterial blood in at least a labeling region (144) thereof, performing a first readout module (202) to obtain first MR information of the subject of interest (120) in a region of interest (142) using first parameters, performing a second readout module (204) to obtain second MR information of the subject of interest (120) in a region of interest (142) using second parameters, and performing MR image generation of a region of interest (142) based on the first and second MR information, wherein the first and second parameters of the first and second readout module (202, 204) are chosen to be different parameters. The invention also provides a MR imaging system (110) adapted to perform the above method and a software package for upgrading a MR imaging system (110), whereby the software package contains instructions for controlling the MR imaging system (110) according to the above method.
    • 本发明提供使用动脉自旋标记对感兴趣对象(120)进行磁共振(MR)成像的方法,包括以下步骤:通过将磁场和/或射频(RF)场施加到 用于在至少其标签区域(144)中标记动脉血的感兴趣的主题(120),执行第一读出模块(202)以获得感兴趣区域(142)中的感兴趣对象(120)的第一MR信息(142) )使用第一参数,执行第二读出模块(204),以使用第二参数获得感兴趣区域(142)中感兴趣对象(120)的第二MR信息,并且执行感兴趣区域(142)的MR图像生成 ),其中第一和第二读出模块(202,204)的第一和第二参数被选择为不同的参数。 本发明还提供一种适于执行上述方法的MR成像系统(110)和用于升级MR成像系统(110)的软件包,由此软件包含有用于控制根据上述的MR成像系统(110)的指令 方法。
