Comparison of image reconstructions from conventional consecutive-slice and proposed FLEET-ACS data acquisition strategies, demonstrating SNR discontinuity is caused by a discontinuity of the time-series standard deviation rather than from a discontinuity in image intensity. Panels show time-series mean image intensity, time-series standard deviation, and time-series SNR from an example 3T subject. (Native axial images are displayed next to sagittal reformats.) Discontinuity is seen in the tSNR of consecutive-slice multi-shot EPI ACS data for both R=2 acceleration (2-shot ACS data) and R=3 acceleration (3-shot ACS data) and is absent in FLEET-ACS data.
