Rapid 2D Na MRI of the calf using a denoising convolutional neural network.

Magnetic resonance imaging 38642779
PURPOSE: Na MRI can be used to quantify in-vivo tissue sodium concentration (TSC), but the inherently low Na signal leads to long scan times and/or noisy or low-resolution images. Reconstruction algorithms such as compressed sensing (CS) have been pr...
