FIELD: medicine, pharmaceutics.
SUBSTANCE: invention refers to chemical-pharmaceutical industry and medicine and represents a contrast agent for T1 and/or T2 magnetic resonant scanning consisting of a nano-sized superparamagnetic powder of cubic cobalt ferrite spinel CoxFe3-xO4, wherein 0.1 ≤ x ≤ 0.99 of particle size 3÷20 nm.
EFFECT: invention provides preparing the contrast agent having a simultaneous effect on relative positive T1 and negative T2 contrasts in magnetic resonant scanning.
