Consensus on a common SNR/CNR definition for fMRI data might be difficult to achieve, because the measurement depends very much on how the signal of interest and the noise is defined. nal-to-noise ratio (sĭg′nəl-tə-noiz′) n. 1. Signal-to-noise ratio ( SNR) is used in imaging to characterize image quality. What does SNR stand for? In MRI the signal-to-noise ratio is measured frequently by calculating the difference in signal intensity between the area of interest and the background (usually chosen from the air surrounding the object). Whereas the 31 SNR would be used at around 95dB level, again being dependant on your noise survey with both examples. Therefore, we strongly recommend that authors reporting SNR/CNR values, at least mention the type of definition they use and provide an interpretation on the meaning of the reported values.
