Correlation of Standard and Volumetric Measurements between Two Neuroradiologists. Correlation of measurement between two neuroradiologists is demonstrated. The calculated ICC is shown as an assessment of the interobserver variability of radiographic measurements for each measurement method.a
| ICC | ||
|---|---|---|
| Percent change from baseline | 1D | 0.42 |
| 2D | 0.61 | |
| Volumetric | 0.97 | |
Abbreviations: 1D, one-dimensional; 2D, two-dimensional; ICC, intraclass correlation coefficients.
