CT scans find missed gout

CT scans can help detect cases of gout that have otherwise proved negative on needle aspirate, a study from the Mayo Clinic shows. 

Dual-energy CT scans identified gout in one-third of patients whose aspirates tested negative for the disease, found the study of over 80 patients with active gout or other joint diseases.

The overall sensitivity and specificity of the scan for diagnosing gout was 0.90 and 0.83 respectively, the researchers reported in this week’s Annals of the Rheumatic Diseases.
