Analysis of T2*WI WM/GM and T2WI signal changea
| Measure | T2WI− (n = 61) | T2WI+ (n = 37) | P Value |
|---|---|---|---|
| mJOA | 17.0 ± 1.6 | 13.6 ± 2.8 | 7 × 10−9 |
| MCL T2*WI WM/GM | 0.862 ± 0.033 | 0.905 ± 0.037 | 2 × 10−7 |
| MCL T2*WI WM/GM ∼ mJOA | −0.43 (9 × 10−4) | −0.36 (0.03) |
↵a The entire cohort (including subjects with DCM and healthy subjects) is divided into subjects with and without T2WI hyperintensity, denoted T2WI+ and T2WI−, respectively. Mean ± SD are reported. T2*WI WM/GM is extracted from the MCL (subjects with DCM) or C4–5 (healthy subjects), and Pearson correlation coefficients between mJOA and T2*WI WM/GM within each signal change group are shown (P values in parentheses).
