Abstract
A system and method for acquiring magnetic resonance imaging (MRI) images with an MRI system is provided. The system and method directs the MRI system first to produce an inversion recovery radio frequency (RF) pulse, wait for a time period, produce a T2-preparation RF pulse, wait for another time period, and then acquire data of a part of a subject. The first produced RF pulse rotates net magnetization 180 degrees about an axis. The pulse sequence used to acquire data can be any two-dimensional or three-dimensional sequence used to acquire a volume in the subject. The two waiting time periods are chosen such that the signals of two or more tissues of the subject are nulled.
