Abstract:
1. A method for producing, with a magnetic resonance imaging (MRI) system, an image indicative of an imaging volume within a subject, the steps comprising: a) acquiring from the imaging volume, a saturated image data set that is sensitized to at least one blood flow velocity by directing the MRI system to perform a pulse sequence that includes: b) acquiring from the imaging volume, a non-saturated image data set by directing the MRI system to perform a pulse sequence that acquires the non-saturated image data set such that magnetization of blood flowing into the imaging volume is substantially not saturated; c) reconstructing a saturated image from the saturated image data set; d) reconstructing a non-saturated image from the non-saturated image data set; and e) producing, by subtracting the saturated image from the non-saturated image, a difference image indicative of blood flow in the imaging volume within the subject that occurs at the at least one blood flow velocity.
