Theranostics

Theranostics, also known as theragnostics, is a technique in personalised medicine and nuclear medicine where a one radioactive drug is used to identify (diagnose) and a second radioactive drug is used to treat cancerous tumors.

In other words, theranostics combines radionuclide imaging and radiation therapy which targets specific biological pathways. Technologies used for theranostic imaging include radiotracers, contrast agents and positron emission tomography. It has been used to treat thyroid cancer and neuroblastomas.
