| Sensitivity | Specificity | Dichotomous pMRI vs. SOC (κ) | Continuous pMRI vs. SOC (ICC) | |
|---|---|---|---|---|
| All SW Versions | 0.93 | 0.96 | 0.87 | 0.94 |
| RC3/RC4a | 0.80 | 0.95 | 0.75 | 0.73 |
| RC5/RC6b | 1.00 | 0.96 | 0.90 | 0.97 |
| RC7/RC8c | 1.00 | 1.00 | 1.00 | 1.00 |
SW, software; κ, kappa statistic; ICC, intraclass correlation coefficient; pMRI, portable MRI; SOC, standard-of-care imaging.
