  • a McNemar and Wilcoxon signed rank tests were used to determine the difference in prevalence and sum of CMBs, respectively; analysis was done separately between T2* and TSWI, T2* and tSWI, and TSWI and tSWI. “All Raters” represents the median value of all separate ratings for all patients (ie, not the final values). The whole cohort is included in the analysis (N = 246). For “Prevalence,” values are given as the number of patients (percentage). All significant values are designated in the Table. All P values have been Bonferroni-corrected.

  • b P < .05 between T2* and tSWI.

  • c P < .05 between T2* and TSWI.

  • d P < .05 between TSWI and tSWI.
