T2prep sequence produces accurate four-point T2maps at ES within a 24-second breathhold. Demonstrated on phantoms and healthy human volunteers to present superior results.
Representative result mid-LV T2map image with LV segmentation lines (green and red) transferred after being drawn on a T2Prep TEmin=15 ms image. This T2map has good consistency and minimal “bad” mapping pixels.
T2Prep T2mapping Sequence. ECG-triggered with a T2prep module, followed by a delay, then a ramped flip angle readout module (bSSFP or FLASH) acquires four successive images at or soon after end-systole.
