The MS Excel calculator was applied to estimate costs and analyze impact on the budget under treatment of multiple sclerosis exacerbations, that were diagnosed using various gadolinium-containing contrast mediums. The direct medical costs for diagnostics with gadolinium-containing contrast medium and hospitalization due to exacerbation in accordance with mandatory medical insurance system were taken into account. At the expense of reducing number of multiple sclerosis exacerbations due to the use of single-molar gadolinium-containing contrast medium (gadobutrol) as compared with semi-polar gadolinium-containing contrast medium (gadodiamide, gadoteric acid and gadoteridol) in 1000 patients it is possible to reduce financial expenses from 1,968,642 to 7,175,520 RUB. The cost of magnetic resonance imaging diagnostics with contrast enhancement and treatment of multiple sclerosis exacerbations increases in the series: gadobutrol < gadodiamide (Jodas Expoim) < gadodiamide (GE Health Care) < gadoteridol < gadoteric acid.
