Case: Dual Energy Gout – Knee
Case history
DECT images of patients with known gout. Images of the right knee reveals uric acid (UA) deposits along the collateral & cruciate ligaments and in the prepatellar region. It is evident that with the material decomposition algorithm, UA can be clearly depicted in red thereby confirming the diagnosis of gout. DE allows for a specific diagnosis of UA crystal induced arthropathy to be made.
