ADC Benchmark Range for Correct Diagnosis of Primary and Recurrent Middle Ear Cholesteatoma

Figure 3

Proposed ADC ranges (mean ADC value ± 1,96 standard deviation σ → confidence interval 95%). (1) Reference range for cholesteatoma: 318 × 10⁻⁶ mm²/s–1265 × 10⁻⁶ mm²/s. (2) Reference range for noncholesteatomatous inflammatory lesions: 1774 × 10⁻⁶ mm²/s–2658 × 10⁻⁶ mm²/s.
