New CT scanner tested for better joint cartilage imaging

This study tested whether a cone-beam CT scanner (often used for dental imaging) can detect cartilage damage in the wrist, ankle, elbow, and knee as well as a standard multidetector CT scanner. 69 adults who needed an arthroscan (a CT scan after dye injection into the joint) were enrolled. Each participant received both types of scans, and radiologists compared the images to see if the cone-beam CT was equally good at finding cartilage problems.
