rs | P | |
1.5T discrete foci: total cerebral number | 0.69 | 0.005 |
1.5T discrete foci: total cerebral volume | 0.70 | 0.006 |
3T discrete foci: total cerebral number | 0.74 | 0.0001 |
3T discrete foci: total cerebral volume | 0.72 | 0.0002 |
Note:—rs = Spearman correlation coefficient. According to Choi's test for correlations, there was no difference in the correlation between age and number of hyperintense foci (p = 0.2) or age and hyperintense foci volume (p = 0.3) when comparing the 2 scanners. See also Fig 3.
