noiseThe degree of diffusion anisotropy in different brain regions is usually measured by a diffusion anisotropy index (DAI) such as relative anisotropy (RA) and fractional anisotropy (FA). FA has been reported to have a higher contrast-to-noise ratio (CNR) than RA. The present work compares...
Signal-to-Noise or Contrast-to-Noise Ratio SNR is driven by image properties (e.g. resolution, bandwidth, TE), while contrast-to-noise ratio (CNR) additionally reflects diffusion contrast (e.g. b-value). There are always tradeoffs between SNR/CNR, image fidelity, and contrast, as well as...
