MSE = 7.688e-11 +/- 1.044e-10 NMSE = 0.03413 +/- 0.058 PSNR = 32.45 +/- 8.1 SSIM = 0.7501 +/- 0.2546
Singlecoil 8x:
MSE = 1.144e-10 +/- 1.722e-10 NMSE = 0.04438 +/- 0.0683 PSNR = 30.95 +/- 7.13 SSIM = 0.6916 +/- 0.2941

Multicoil 4x
MSE = 1.882e-11 +/- 4.54e-11 NMSE = 0.006153 +/- 0.0148 PSNR = 38.94 +/- 5.915 SSIM = 0.9157 +/- 0.1188
