FIELD: medicine.
SUBSTANCE: invention relates to method of obtaining medication for roentgenologic examination by processing suspension of tantalate of element, selected from group, which includes yttrium, lanthanum, cerium, praseodymium, neodymium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium in mode of percussive mechanical loadings with intensity not less than 10 g, in presence of sodium salt of carboxymethylcellulose (Na-CMC), taken in quantity 0.5-1.5 wt % from the total mass.
EFFECT: invention ensures high contrast of image and stability of medication for a long time due to obtaining suspension, which contains nano-size particles.
