Abstract
A method for operating a Magnetic Resonance (MR) imaging system that includes generating radio frequency (RF) excitation pulses in a volume of patient anatomy and generating slice select magnetic field gradients for phase encoding and readout RF data acquisition in the patient anatomy. The method further includes concurrently acquiring T1 map image data of slices of an image by: (i) acquiring image calibration data using a pre-scan sequence; (ii) inverting a longitudinal magnetization in the volume of patient anatomy using a non-selective inversion recovery pulse; (iii) applying an excitation RF pulse to different slices in the volume of patient anatomy to rotate a portion of the longitudinal magnetization in a transverse direction; (iv) sampling individual slice image data of the slices in response to applying the excitation RF pulse; and (v) separating the concurrently acquired T1 map image into separate slices.
