Knee injuries are among the most common injuries of the musculoskeletal system. Unfortunately, static MRI often does not lead to satisfying diagnoses, especially in difficult cases. We developed a motion device and in collaboration with Rapid Biomedical a 16 channel U-shaped coil array to enable dynamic imaging of the knee for a characterization of the complex motion of the knee or therapy monitoring after cartilage or ligament reconstruction. A triggered, segmented, dynamic multislice MRI sequence was used to acquire 4D datasets in 8 minutes which can be visualized as several compartments (femur, tibia, patella, infrapatellar fat pad, cruciate ligaments).
