Repeat measurement accuracy of estimation methods in 20 randomly selected vestibular schwannomas*
| Measurement Method | Error in Units of Measurement | Average % Error Relative to Size |
|---|---|---|
| Maximal diameter | 1.8 mm (8.5–0.2) | 15 (114–0.9) |
| Manually segmented volume | 150 mm3 (430–4) | 18 (112–2.0) |
| Bayesian classification volume | 70 mm3 (342–1) | 7 (22–0.3) |
* Percentages in parentheses are the ranges in measurement errors with respect to diameter or volume of each initial tumor measurement.
