What does an MRI of the wrist show?

MRI often reveals carpal bone cysts, commonly called bone ganglia, and demonstrates their relation to cortical defects, ligament injuries and associated soft tissue ganglia. Found most often in the scaphoid and lunate, bone ganglia may be differentiated from subchondral cysts due to associated deep chondropathy.

What are the routine projections for the wrist?
