Difference in quantitative measurements of lacrimal gland between active and inactive Graves' ophthalmopathy.
| Measurement | Inactive (40 eyes) | Active (26 eyes) | P-value |
|---|---|---|---|
| Axial width (mm) | 6.1±3.8 | 5.1±1.1 | 0.194 |
| Axial length (mm) | 15.9±3.4 | 16.7±3.7 | 0.363 |
| Axial area (mm2) | 68.63±20.97 | 68.90±31.49 | 0.966 |
| Coronal width (mm) | 5.4±0.9 | 5.4±1.2 | 0.866 |
| Coronal length (mm) | 16.3±2.8 | 16.0±4.5 | 0.711 |
| Coronal area (mm2) | 68.42±17.6 | 70.36±29.74 | 0.766 |
| Volume (cm3) | 0.737±0.250 | 0.676±0.367 | 0.425 |
| SIR | 2.34±0.36 | 2.72±0.51 | 0.001 |
SIR indicates the signal intensity ratio of the lacrimal gland to the ipsilateral temporal muscle on fat-suppressed T2-weighted imaging.
