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 |
