Radiolabeling and in vitro evaluation of 99mTc-methotrexate on breast cancer cell line

In the present study 99m Tc-MTX was prepared with high labeling yield by a new simple and easy formulation method. According to cell culture studies, 99m Tc-MTX incorporated with both MCF-7 and CRL8798 cells, with significant differences in the uptake percentages. Since 99m Tc-MTX highly uptake in cancer cell line, the results demonstrated that radiolabeled MTX may be promising for breast cancer diagnosis of oncological patients.
