Abstract:
1. A method for producing an image using a magnetic resonance imaging (MRI) system, the steps comprising: a) performing a first preparatory stage of an MR pulse sequence to suppress a transverse magnetization of a first spin-species having a first T b) performing a first imaging stage of the MR pulse sequence using projection imaging to sample a first free induction decay signal from a second spin species having a T c) performing a second preparatory stage of the MR pulse sequence to suppress the transverse magnetization of the first spin-species and invert a longitudinal magnetization of a desired spin-species; d) performing a second imaging stage of the MR pulse sequence using projection imaging to sample a second free induction decay signal from the second spin species and produce a second image data set; and e) reconstructing the first and second image data sets to produce an MR image including the second spin species that is substantially free of the first spin-species.
