[Value of the technique of intravenous infusion of contrast media for the diagnosis of fluid processes (author's transl)].

The study covered 50 patients suffering from hepatic effusions; a solution used in contrast intravenous psychography was administered to them by the intravenous route, at similar doses to those used in intravenous psychography with infusions. This process which we have called Intravenous Viscerogramme, because of the similarity of the images obtained with those of the viscerographic phase of arteriography, has enabled the diagnosis of 35 hydatidiform cysts, one case of cholangiolar hamartoma and an abscess. Owing to the ease with which it can be carried out, we think that it can be used in the diagnosis of tumoral lesions of the liver. When the result is positive, radiological signs are obtained which enable identification of the lesion, thus avoiding resorting to more complex investigations such as angiography.
