WebThe R2* value for Phantom I was much greater than the R2* value for Phantom III (R2*=155 s-1 vs. R2*=80 s-1 for high SNR data measurement); signal within Phantom I images decayed more rapidly to the noise floor. For both phantoms at later TEs, OBC images demonstrated decreased noise levels compared to RSS images.
