What are the components of radiopharmaceuticals?
Radiopharmaceuticals generally consist of two components, a radioactive element (radionuclide), that permits external scan, linked to a non-radioactive element, a biologically active molecule, drug or cell (red and white blood cells labeled with a radionuclide, for example) that acts as a carrier or ligand, responsible …
Why are radiopharmaceuticals important?
Why Use Radiopharmaceuticals? Every organ in our bodies acts differently from a chemical point of view. Nuclear medicine researchers have identified many chemicals and how specific organs absorb them. With this knowledge, radiopharmacists are able to attach various radioisotopes to biologically active substances.
What are the application of radiopharmaceuticals?
Diagnostic radiopharmaceuticals can be used to examine blood flow to the brain, functioning of the liver, lungs, heart or kidneys, to assess bone growth, and to confirm other diagnostic procedures. Another important use is to predict the effects of surgery and assess changes since treatment.
How is radiopharmaceuticals used in treatment?
Radiopharmaceuticals are part of an approach called theranostics, which relies on a lab-produced drug to carry radioactive isotopes to specific cancer cells, sometimes attached to low-dose radiation to map a cancer and sometimes to high-dose radiation as therapy.
What are the advantages of radiopharmaceuticals?
Radiopharmaceuticals appear to have fewer side effects than traditional radiation therapy and are better equipped to target cancer cells. Targeted radiopharmaceutical therapy, also called molecular radiation therapy, may be effective on both isolated tumors and on metastatic cancer that has spread throughout the body.
What is a radiopharmaceutical isotope?
Radiopharmaceuticals are radioisotopes bound to biological molecules able to target specific organs, tissues or cells within the human body. These radioactive drugs can be used for the diagnosis and, increasingly, for the therapy of diseases.
