Analysis of Intraobserver and Interobserver Reliability for Magnetic Resonance Imaging Measurement

Variable SNR* Width of the ATFL
Intraobserver agreement
Reader 1 0.78 (0.66~0.89) 0.92 (0.83~0.99)
Reader 2 0.82 (0.69~0.92) 0.89 (0.78~0.98)
Reader 3 0.67 (0.47~0.84) 0.83 (0.69~0.95)
Interobserver agreement
Reader 1-Reader 2 0.69 (0.51~0.88) 0.86 (0.75~0.97)
Reader 2-Reader 3 0.54 (0.38~0.69) 0.69 (0.54~0.85)
Reader 1-Reader 3 0.61 (0.45~0.79) 0.78 (0.68~0.89)

Values are presented as intraclass correlation coefficient (95% confidence interval).

SNR: signal-noise ratio, ATFL: anterior talofibular ligament.

*SNR was calculated using the following equation: SNR=signal intensity of

ATFL/signal intensity of background.
