↵a Data indicate the mean ± SD.
↵b There were no significant differences between DSA and HR-MR (P > .05).
↵c There were significant differences between DSA and HR-MR (P < .05).
↵d Agreement refers to the interclass correlation coefficients between DSA and HR-MR, and data in parentheses indicate 95% confidence intervals.
↵e Agreement refers to the κ values between DSA and HR-MR, and data in parentheses indicate 95% confidence intervals.
