From: Imaging the implant-soft tissue interactions in total knee arthroplasty

  CT MRI
Advantages • Fast
• Not expensive
• Possible for full lower limb
• Possible on fresh-frozen cadavers
• Adequate visualisation of bone and soft tissues
• Visualisation of all the soft tissues
Disadvantages • Needs injection of barium-sulfate
• Impossible to inject all structures
• Contrast medium does not reach the bony insertions
• Time consuming
• Expensive
• Needs transection of femur and tibia to flex the knee
• Poor image quality for bone and implant
• Require temperature monitoring
