Table 3.

Diagnostic accuracies of 13 diagnostic criteria, calculated for pre-contrast MR scans and post-contrast MR scans as relative agreement with the standard of reference (1.00=100%) in 119 patients. The numbers in brackets represent the 95% Confidence intervals. A difference with a confidence interval not straddling zero was considered significant.
