Magnetic Resonance Imaging (MRI) plays a crucial role in diagnosing early synovial osteochondromatosis (SOC), as it is particularly effective in visualizing the non-calcified or minimally calcified loose bodies within the joint space. MRI allows for the detailed assessment of the synovial lining and the identification of the characteristic cartilaginous nodules that develop in SOC. These nodules can be challenging to detect using plain radiography, especially in the early stages when there is little to no calcification.

MRI is beneficial because it provides high-resolution images that can outline the morphology and number of intra-articular loose bodies and assess the condition of the surrounding soft tissues and synovium. This imaging modality is vital for making an accurate diagnosis before significant joint damage occurs [source].
