ABSTRACT:
A needle tipped with a plating of radioactive metal and covered with additional layers of plating to prevent subsequent rubbing off of radioactive material, decreases local or systemic reactions to the plating materials, and prevents decomposition of the underlying plating materials. The radioactive tipped needle can be used in conjunction with nuclear medicine imaging techniques to identify and localize abnormalities that may not be seen using other radiographic techniques. A method for producing the needle is also described.
