**Note:—**rCBV indicates relative cerebral blood volume; mean_{50,}mean of the top 50% of the histogram; SD_{50}, SD of the top 50%; mean_{25}, mean of the top 25%; SD_{25}, SD of the top 25%; mean_{10}, mean of the top 10%; SD_{10}, SD of the top 10%; skew, skewness; kurt, kurtosis; PH, peak height of the histogram; PP, peak position (ie, the mode); and A1SD, area under the histogram curve within 1 SD. The highest correlations in each category are underlined; the metrics achieving significance are in bold.
