CT scans are also very useful to evaluate for adverse wear failure (AWF) around metal bearings in certain circumstances. Similar to simple x-rays, but unlike MRI they do expose the patient to a low dose of x-rays. They are less costly and allow imaging of both hips simultaneously. Metal suppression techniques also need to be used.

We are currently working on advanced techniques to accurately measure implant positions in 3 dimensions on these scans. We hope this will eventually allow us to develop more accurate guidelines as well as surgical guides for implantation during surgery.
