The radiographic appearance of calcified nodules in synovial osteochondromatosis typically features multiple intraarticular calcifications. These calcifications are commonly round or oval in shape and may present with a "ring-and-arc" pattern. In the advanced stages, they may ossify, giving a more clearly defined appearance. Below are some key characteristics and accompanying images depicting these features:

1. Concentric Ring Pattern: The calcifications may present as concentric rings, indicating ossification within the synovial tissue.
2. Popcorn-ball Appearance: These calcified cartilage nodules often have a distinct appearance, sometimes described as resembling popcorn.

Here are some images illustrating these radiographic appearances:
