A method for measurement of the uptake patterns of two beta-emitting radionuclides in the same tissue section with a digital silicon detector: application to a study of 89SrCl2 and 153Sm-EDTMP in a dog with spontaneous osteosarcoma
The biological effect of a radiopharmaceutical depends heavily on the heterogeneity of the uptake in the various tissues. A comparative study of two radiopharmaceuticals should therefore include a comparison ...
