From: MRI-detected osteophytes of the knee: natural history and structural correlates of change

Sample images show magnetic resonance imaging (MRI)-detected osteophyte (OP) progression. a Tibial MRI-detected OP increases from baseline to follow up (wider arrow indicates follow-up MRI-detected OP). b Femoral MRI-detected OP increases from baseline to follow up (wider arrow indicates follow-up MRI-detected OP)
