Five percent of adult African-Americans and 4 percent of whites in the U.S. have gout. The nation’s obesity CT Scan Gout2epidemic is thought to be a factor behind the increase in gout cases.
Gout is often thought of as a man’s disease and associated with sudden sharp, burning pain in the big toe. It’s true that until middle age, more men than women get gout, but after menopause, women catch up in the statistics. And gout can hit more than the big toe: Other joints including parts of the feet, ankles, knees, fingers, wrists and elbows can be affected.
“The first flare of gout most commonly occurs in the big toe, but gout can affect pretty much every joint in the body, and the more gout flares you have the more likelihood that other joint areas will be affected,” Dr. Bongartz says.
An accurate and early gout diagnosis is crucial because gout patients are treated with different medication than people with other forms of inflammatory arthritis, and proper medication and dietary changes can help prevent further gout attacks and the spread of the disease to other joints.
“What we are learning from the dual-energy CT scans has really changed our perception of where gout can occur and how it can manifest,” Dr. Bongartz says. “The ability to visualize those deposits clearly broadens our perspective on gout.”
The study co-authors included researchers from Mayo Clinic radiology, rheumatology, orthopedic surgery, family medicine and biomedical statistics and informatics.
