This work introduces a reconstruction-only approach, dubbed “single echo reconstruction” (SER) to demonstrate (i) the first, rapid 128 x 128 MRI without phase encoding using a 64-channel coil; (ii) significant reduction of RF power, PNS, and gradient noise; (iii) using only a commercially available coil with no external sensors (iv) comparison with gold-standard 2D spin-echo (SE) and accelerated acquisitions for $$$ T_2 $$$ weighted imaging as an application. For imaging 11 slices with TE = 80ms, the acquisition time was 1.8s with 10.8W total RF deposition, 12.09% peripheral nerve stimulation and no blurring artifacts.
