The Claim
Dual-energy spectral CT quantifies uric acid concentration in tophi at approximately 1268.8 ± 32.2 mg/cm³, which is significantly higher than concentrations in muscle (1143.5 ± 15.7 mg/cm³) and cancellous bone (1070.9 ± 26.4 mg/cm³), enabling differentiation of gout deposits from adjacent tissues based on chemical composition.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Dual-energy spectral CT can measure the amount of uric acid in gout deposits called tophi and distinguish them from nearby muscle and bone tissue based on their chemical composition.

Uric acid builds up in dense crystals inside gout lumps, and these crystals absorb X-rays differently than muscle or bone, so a special CT scan can tell them apart by how much X-ray energy they block.
What the research says
1 studyStudy: Detection of uric acid depositing in tophaceous gout using a new dual energy spectral CT technology
This study shows that a special CT scan can measure how much uric acid is in gout lumps, and it finds that these lumps have more uric acid than nearby muscle and soft bone — which helps doctors tell them apart. It’s like using a color detector to spot red apples among green ones.
