The study of the chemical and physical properties of radioactive elements is stated as radiochemistry. Radiochemists use both the radioactive and chemical properties of elements and compounds to fulfil technological needs in a variety of fields, including environmental speciation and behavior, radioactive waste treatment and disposal, and beneficial uses of radioactive materials in medicine. Radiopharmacology is the application of radiochemistry to medicine, and also the pharmacy of radiopharmaceuticals (medicinal radio compounds, i.e., pharmaceutical drugs that are radioactive). Radiopharmaceuticals are applied as radioactive tracers in medical imaging and therapy for a variety of disorders in nuclear medicine.
Hybrid imaging is a technique that combines two or more imaging modalities to create a new or more powerful modality. Hybrid imaging allows for a similar natural integration of data from functional and structural imaging modalities without having a thorough understanding of the technologies involved.
Nuclear medicine can be stated as a branch of medication that deals with the utilization of radioactive substances in disease, diagnosis and therapy. Nuclear medicine imaging is "radiology done inside out" or "endoradiology" in that it records radiation emitted from within the body rather than radiation emitted from outside sources such as X-rays. Furthermore, nuclear medicine scans differ from radiology in that the focus is on the function rather than the anatomy. Nuclear medicine is a multidisciplinary field that combines medicine, physics, and pharmacy. The radio pharmacy is a crucial component of nuclear medicine, and one of its main responsibilities is to prepare high-quality radiopharmaceuticals, which are the foundation for a high-quality nuclear medicine examination.
