  • Look-locker IR-SSFP for cardiac MR imaging with simultaneous generation of cardiac T1 maps, cine images and IR-prepared images
    Patent number: 9008753
    Abstract: The present invention is directed to a method for use in conducting cardiac MR imaging which allows for reconstruction of T1 maps, cine images and IR-prepared images from one raw data set, wherein the method comprises the following steps: a) acquisition of raw data by use of an ECG-triggered, segmented, inversion recovery (IR) -prepared Look-Locker type pulse sequence for data acquisition, wherein the pulse sequence encompasses more than one shot, wherein each shot comprises: i) an ECG-triggered inversion pulse; ii) SSFP cine data acquisition of radial segmented profiles over more than one RR-interval for a predefined acquisition duration AD; and iii) a relaxation duration RD, during which no data is acquired; b) retrospective gating of raw data by sorting acquired raw data for each RR-interval into a pre-determined number of heart phases by definition of specific time windows within the RR-intervals and sampling of raw data acquired during the time windows respectively; c) image reconstruction, wherein the r
