Utility of white matter disease and atrophy on routinely acquired brain imaging for prediction of long-term delirium risk: population-based cohort study.

For patients admitted within 5 years after baseline imaging, MRI-defined WMC were associated with delirium (OR = 9.28, 2.27–38.0, P = 0.002) but associations with CT-defined WMC were less strong and just failed to reach significance (OR = 3.33, 0.92–12.11, P = 0.07, Table 3 ).
