Abstract
Application of Ferrite as a Contrast Media to Gastrointestinal X-ray Diagnosis (I).
Ferrite is a strongly magnetic substance and can be used for a contrast media in the gastrointestinal x-ray examination, as have been pointed by a few authors.
We studied radiologic properties of the solution of this subatance. When comparing with the barium sulfate solution, the most common contrast media for the gastrointestinal x-ray examination, the ferrite solution is less flocculant even by increased acidity, and it shows better coating of a surface.
In those experiments which test x-ray absorption, homogenousity and sedimentation of the solution, it was proved that the ferrite is inferior to the barium sulfate. So, some problems are unresolved on the clinical use of this contrast media.
In demonstrating a numder of models simulating to both elevated and depressed lesions of the gastric wall the ferrite solution made to be detectable smaller changes than the barium sulfate.
The second series of our further experiments indicate that, if a lesion is located on the anterior wall of the upper portion of the stomach, an improved radiological examination will be expected with the ferrite solution.
