Why do I need a standing CT scan?

For lower limb surgeons, being able to see the joint spacing and bone positioning in a load-bearing, functional position is very important. Because we use Conebeam CT, 3D weight-bearing scans are available at a radiation dosage that is roughly equivalent to the corresponding X-ray set. Traditional weight-bearing X-rays can be problematic as they can take time to position the patient correctly and multiple X-rays are required which takes time and is not consistently reproducible. With our standing CT scans, the contralateral limb is also always imaged at the same time, as a control.
