Osteoarthritis
Osteoarthritis Knee (left image)
Asymmetrical joint space narrowing, subchondral sclerosis and osteophyte formation on lateral femoral condyle.
Severe Osteoarthritis (right image)
Specific features include joint space narrowing and subchondral sclerosis.
Cervical Degeneration
C4-5, C5-6 severe degeneration. Narrowed disc space and collapse of vertebral body.
Ankylosing Spondylitis – Sacroiliitis
Earliest sign of AS is indistinctness of the sacroiliac joint. Subchondral bony erosions, subchondral sclerosis, and bony proliferation may eventually lead to bony fusion. In the later stage, the sacroiliac joint may not be visible or may present only as a thin dense line. Bamboo spine, also prominent here, is an AS feature caused by syndesmophytes formation.
