Synopsis

Keywords: Quantitative Imaging, KidneyThe overlapping-echo detachment (OLED) imaging can capture a T2 map within about 150 ms. However, when the region of interest (ROI) is smaller than the object, it is inefficient to acquire the whole object because many unnecessary phase-encoding steps should be acquired. The zonal oblique multislice (ZOOM) is a method to reduce the field of view (FOV) by using two pulses to excite two slabs that have a specific angle between them. This study combined ZOOM with OLED to capture the T2 map with reduced FOV. The ZOOM-OLED can reduce geometric distortion and improve image resolution.
