Standard protocol for knee MRI. The coronal STIR sequence was exchanged for the coronal PD SPAIR sequence in the two last examinations.
| Scan sequence | Scan plane | TR | TE | Section thickness (mm) | Gap (mm) |
|---|---|---|---|---|---|
| TSE T1W | Coronal | 560 | 17 | 3 | 0.6 |
| STIR | Coronal | 3912 | 30 | 3 | 0.6 |
| PD | Sagittal | 4500 | 30 | 3 | 0.3 |
| PD SPAIR | Axial | 3423 | 30 | 3 | 0.3 |
| PD SPAIR | Coronal | 3500 | 30 | 3 | 0.3 |
PD, proton density; SPAIR, spectral attenuated inversion recovery; STIR, short tau inversion recovery; T1W, T1-weighted; TE, echo time; TR, repetition time; TSE, turbo spin-echo.
