Table 2 Advantages and disadvantages between MRI and CT-scan

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
