| Active arthropathy (acute stage) | Mild inflammation/soft tissue oedema | Severe inflammation/soft tissue oedema | No skeletal deformity | Severe skeletal deformity | X-ray: normal | X-ray: abnormal | MRI: abnormal (bone marrow oedema, microfractures, bone bruise) | MRI: abnormal (bone marrow oedema, macrofractures, bone bruise) |
| Inactive arthropathy (becalmed stage) | No inflammation | No inflammation | No skeletal deformity | Severe skeletal deformity | X-ray: normal | X-ray: abnormal (past macrofractures) | MRI: no significant bone marrow oedema | MRI: no significant bone marrow oedema |
