Description

Tristan T. Demmert and ten colleagues tested a new algorithm for cleaning up CT scans around metal implants, where streak artifacts often hide the very bone doctors need to inspect. Their experimental study scanned three cow femur bones fitted with titanium hip nails on a photon-counting scanner.

Images were rebuilt three ways: untouched, with the current artifact-reduction software, and with a prototype that exploits the scanner's built-in spectral data. Artifact severity next to the implant fell at each step, and three radiologists rated the prototype best on every quality measure. The older software also introduced fresh artifacts near the metal, which the prototype avoided. The authors see promise for judging implant complications such as loosening.
