Objective: To evaluate availability of dual-source computed tomography (CT) for representative joint pathologies and to document the findings of each.
Methods: We used dual-source CT to evaluate representative joint diseases. Dual-source CT has two X-ray tubes and can produce two different X-ray energies (80 KV and 140 KV) at the same time. We analyzed CT values of each structure obtained by dual-source CT, and distinguished one from the others using the three-material decomposition theory.
Results: Dual-Energy Imaging produced virtual non-contrast (VNC) images, which detected several clinically important joint pathologies such as articular cartilage defect of the knee joint, labral tear of the hip, and triangular ligament tear of the wrist.
Conclusion: VNC imaging obtained by dual-source CT is considered to be valuable in the evaluation of joint pathologies.
