MRI scans are a method of visualising the soft tissue components of a joint, not well seen on x-rays.
When interpreted by an experienced radiologist a scan will identify the majority of injured structures. MRI is especially sensitive and specific for the diagnosis of ACL, PCL, MCL and meniscal injuries. Any subtle bone injuries are easily identified. MRI is not so good at identifying PLC, LCL and capsule injuries, especially after the initial healing period.
