Duodenitis: endoscopic-radiologic correlation in 272 patients

Potential radiologic findings of duodenitis were investigated in 272 patients, 157 with endoscopically diagnosed duodenitis and 115 endoscopically normal controls. The study assessed the value of four signs: folds more than 4 mm thick, mucosal nodules, bulbar deformity, and erosions. The most sensitive signs were thickened folds (72.0%) and nodularity (48.4%), while demonstration of erosions was the least sensitive (10.8%). Overall sensitivity (77.7%) approximated that for the radiologic diagnosis of peptic ulcer or esophagitis. Radiologic specificity (76.5%) was in the same range.
