3-T high-resolution axial T2-weighted images of a patient with adenocarcinoma of rectosigmoid junction. (a) Image acquired with a standard clinical protocol with a number of signal excitations (NEX) of 2, with arrow showing a mass with irregular infiltrative margins. (b) Image acquired with an identical scan protocol and patient setup, except with the NEX reduced to 1 and thus scan time reduced by half as compared to (a). An expected reduction in SNR is noted. (c) Image generated from a DL-reconstruction algorithm using the same acquisition as in (b). Notice the restoration of SNR without loss of resolution compared to (b)
