Alteration of the organ uptake of the 99mTc-radiopharmaceuticals, 99mTc-DPD, 99mTc-DMSA, 99mTc-tin colloid and 99mTc-MAA, induced by the applied cytotoxic drugs methotrexate sodium and cyclophosphamide

These results confirm that both methotrexate sodium and cyclophosphamide may alter the organ uptake of (99m)Tc-radiopharmaceuticals in experimental animals.
