  • Note:—AD indicates Alzheimer disease; Other, other dementias; MCI, mild cognitive impairment; SCI, subjective cognitive impairment.

  • a Differences in prevalence and sum of CMBs were determined with the McNemar and Wilcoxon signed rank test, respectively; analysis was made between T2* and TSWI, T2* and tSWI, and TSWI and tSWI. Ratings represent the median value of all separate ratings for all patients. 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.
