title: Fluoroscopically controlled examination of the upper gastrointestinal tract using low density barium. A review of 139 endoscopically proven lesions.
abstract: 120 of 139 endoscopically verified lesions were diagnosed by fluoroscopically controlled examination of the upper gastrointestinal tract (sensitivity 86%). The incidence of false negative results was 19/139 (14%). The lesions most frequently missed were ulcerations of 1 or 2 mm in size, or lesions obscured by gastric contents. All 16 malignancies were diagnosed radiologically. It is concluded that with proper fluoroscopic-radiographic technique the sensitivity of fluoroscopically controlled examination of the upper gastrointestinal tract is comparable to (or better than) that of double contrast studies.
