T2 mapping heart mri
WebBoth T1 and T2 mapping require multiple images to be obtained at various TR or TE times, respectively, to calculate a relaxation curve, which can then be displayed as an absolute value for a given region of the heart or as an image with an overlaying color map representing the relaxation time [ 14, 15] ( Fig. 3 ). Web(1) Background: Radial RARE-EPI MRI facilitates simultaneous T2 and T2* mapping (2in1-RARE-EPI). With modest undersampling (R = 2), the speed gain of 2in1-RARE-EPI relative …
