- •The concordance between CNFS grading based on axial and oblique sagittal images was strong for all three observers (W = 0.80, 0.79, and 0.82).
- •In case of discordance, oblique sagittal image-based grading tended to result in higher grading than axial-based grading with all three observers.
- •Both axial and oblique sagittal images supported strong interobserver agreement.
- •However, oblique sagittal images provided slightly higher reliability (W = 0.79) than axial images (W = 0.73).
