Abstract
A method and apparatus for marking a lesion in a body part is provided. The method includes the steps of obtaining a first nuclear-emission image of the body part; determining a position of the lesion from the first image; percutaneously introducing a cannula to the determined position; inserting a wire into the cannula, the wire including radioactive material; retracting the cannula while holding the wire in place; and obtaining a second nuclear-emission image of the body part. The second image includes data relating to a position of the lesion and data relating to a position of the wire.
