Synopsis

Keywords: Joint, Joints, Knee; Osseous abnormality; Zero echo time

Motivation: Current imaging techniques for knee joint osseous abnormalities have limitations in radiation exposure and soft tissue contrast. A non-invasive, radiation-free imaging method is needed.

Goal(s): To evaluate the potential of 7T ZTE imaging in detecting knee osseous abnormalities compared to CT.

Approach: A clinical study comparing 7T ZTE and CT for detecting knee joint osseous abnormalities, with qualitative assessment for bone structures by musculoskeletal radiologists.

Results: 7T ZTE demonstrated high diagnostic consistency with CT, providing superior visualization of osteophytes, cortical, and trabecular bone, though it was less effective in delineating epiphyseal lines.

Impact: This study highlights 7T ZTE as a promising, non-invasive, and radiation-free alternative for evaluating knee joint bone abnormalities, potentially enhancing clinical diagnostic accuracy and patient safety.
