title: Radiological examination of the colon.
abstract: In view of the diagnostic limitations of Welin's double-contrast method, which provides no total filling images or mucosal images, a description is given of a so-called universal method of investigation by which a diversity of diseases can be demonstrated. An essential feature of this method is the use of a barium sulphate suspension with experimentally established specific gravity and viscosity. This particular contrast medium has the advantage of permitting of total-filling exposures for assessment of contours and mucosal exposures for the diagnosis of inflammatory diseases and double-contrast method. The specific gravity at a given tube voltage also makes it possible to diagnose polyps after total filling.
