Observer 2^{^e} 0.579 (0.390–0.768) 67.6% (25/37) 32.4% (12/37) 
↵a Agreement refers to κ values between DSA and HR-MR, and data in parentheses indicate 95% confidence intervals.
↵b Data in parentheses indicate the numbers of agreed or disagreed cases compared with the total number of cases in the diagnosis.
↵c The proportions of undetermined diagnosis for observer 1/observer 2.
↵d Interobserver agreement between observer 1 and observer 2.
↵e Intermodality agreement between DSA and HR-MR.
