T1 and T2 values for different ocular structures in a uveal melanoma patienta
| T1 (ms) | T2 (ms) | |
|---|---|---|
| Lens nucleus | 916 | 24 |
| Vitreous body | 4218 | 209 |
| Orbital fat | 112 | 84 |
| Extraocular muscle | 1282 | 56 |
| Eye tumor | 883 | 36 |
| Liquid behind detached retina | 1814 | 64 |
a
T1 and T2 values in milliseconds were averaged over drawn regions of interest. The eye tumor shows different relaxation times (both T1 and T2) compared with the vitreous body and with the liquid behind the detached retina, which allows for discrimination between tumor and healthy tissue.
