A novel chemical method of labeling porphyrin compounds, specifically hematoporphyrin derivative (HPD), with the radionuclide Technetium-99m producing a radioactive tracer material suitable for biomedical applications. HPD labeled with 99mTc is biologically active in vivo and is preferentially taken up by neoplastic tissues. This provides a simple and specific means of visualizing tumors in man or animal by scintigraphic imaging techniques.
