Quantitative Assessment of MRI Data at Each Enrollment Site.
| Enrollment Site | Cohort | SNR | CNR |
|---|---|---|---|
| MSSM + UW | Inclusion Cohort (n = 87) | 15.2 +/− 3.3 | 1.0 +/− 0.3 |
| Exclusion Cohort (n = 9)* | 8.3 +/− 2.6 | 0.9 +/− 0.2 | |
| P value | <0.0001 | 0.65 | |
| MSSM | Inclusion Cohort (n = 66) | 15.1 +/− 2.9 | 1.0 +/− 0.4 |
| Exclusion Cohort (n = 9)* | 8.3 +/− 2.6 | 0.9 +/− 0.2 | |
| P value | <0.0001 | 0.9 | |
| UW | Inclusion Cohort (n = 21) | 15.6 +/− 4.5 | 1.1 +/− 0.1 |
| Exclusion Cohort (n = 0) | – | – | |
| P value | – | – |

For two subjects, the FreeSurfer processing pipeline could not be completed. Thus, only 9 of the 11 excluded patients could undergo signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) analysis. P values were determined using two-tailed T-tests. MSSM = Mount Sinai School of Medicine; UW = University of Washington.
