DUAL-ENERGY COMPUTED TOMOGRAPHY (DECT) SCANS INCREASE THE LIKELIHOOD OF DETECTING TOPHI1

Advanced imaging techniques like DECT scans may reveal urate deposits that are undetectable by physical examination alone. DECT scans use multiple x-rays of different strengths to produce an image that can distinguish substances such as calcium and uric acid crystals from soft tissues in areas where visual inspection would be difficult or impossible.1

Professors Georg Schett, MD and Nicola Dalbeth, MD utilize DECT scans in their research and in diagnosing and monitoring patients with gout.

“Our understanding of the disease has really shifted as we've been able to visualize the disease better. If patients do have tophi, this is an excellent indication for urate-lowering therapy.”

– PROFESSOR NICOLA DALBETH, MD

VISUAL INSPECTION OF TOPHI IS NOT ALWAYS SUFFICIENT

The mere inspection of the patient is not sufficient in chronic gout. We want to actually know what the stage of the disease is. Dual-energy CT scans increase the possibility of finding tophi.

– PROFESSOR GEORG SCHETT, MD
