The mean ± standard deviation of each measure in centimeters derived by NC-MRA and CE-MRA, p values from paired-sample student’s t-test to compare methods, the 95% confidence interval (CI) for the mean difference between methods for the same subject and the percentage of times the measures derived from the same subject differed by at least 3 mm in absolute value.
