AGENT FOR CONTRASTING IN DIAGNOSTIC RADIOLOGY

FIELD: medicine, radiology, pharmacy. ^ SUBSTANCE: invention relates to an agent used in contrasting in carrying out the diagnostic radiology that comprises tantalite of at least one element taken among the group including yttrium, lanthanum, cerium, praseodymium, neodymium, samarium, europium, gadolinium, terbium, holmium, erbium, thulium, ytterbium, lutecium or bismuth, organic additive and water wherein the natural polysaccharide with acid functional groups is used as an organic additive in the definite ratio of components. Invention provides preparing an agent exhibiting uniform distribution of insoluble particles, high effectiveness of absorption in the low dose given to a patient, and high degree of contrasting, the combination of high adhesion to mucosa tissue of organs and good fluidity in applying the external stress that results to increasing reliability of results in carrying out the diagnosis. Invention can be used as X-ray contrast agent in X-ray assay of different organs. ^ EFFECT: valuable properties of agent. ^ 3 cl, 9 ex
