ABSTRACT:
In order to provide a magnetic resonance imaging system and method which allows an optimal timing of the imaging sequence at minimal procedure cost, a magnetic resonance imaging system and method is proposed, wherein a first MR scan of a structure of interest is performed for detecting the arrival of a contrast bolus in the structure of interest, the first MR scan using a first resonance frequency corresponding to first MR sensitive nuclei, the first performing step is repeated at least until the bolus arrival in the structure of interest has been detected, and a second MR scan of the structure of interest is performed for acquiring a MR image, the second MR scan using a second resonance frequency corresponding to second MR sensitive nuclei, the second nuclei being different from the first nuclei.
