Nuclear medicine (nuclear radiology, nucleology), [1] [2] is a medical specialty involving the application of radioactive substances in the diagnosis and treatment of disease. Nuclear imaging is, in a sense, radiology done inside out , because it records radiation emitted from within the body rather than radiation that is transmitted through ...
This is a type of targeted therapy which uses the physical, chemical and biological properties of the radiopharmaceutical to target areas of the body for radiation treatment. [3] The related diagnostic modality of nuclear medicine employs the same principles but uses different types or quantities of radiopharmaceuticals in order to image or ...
As in diagnostic nuclear medicine, appropriate radionuclides can be chemically bound to a targeting biomolecule which carries the combined radiopharmaceutical to a specific treatment point. [3] It has been said that "α-emitters are indispensable with regard to optimisation of strategies for tumour therapy". [4]
Medicine has used radiation therapy as a treatment for cancer for more than 100 years, with its earliest roots traced from the discovery of X-rays in 1895 by Wilhelm Röntgen. [119] Emil Grubbe of Chicago was possibly the first American physician to use X-rays to treat cancer, beginning in 1896. [120]
Theranostics originated in the field of nuclear medicine; iodine isotope 131 for the diagnostic study and treatment of thyroid cancer was one of its earliest applications. [7] Nuclear medicine encompasses various substances, either alone or in combination, that can be used for diagnostic imaging and targeted therapy.
To conclude this section on treating brain tumors with BNCT using reactor neutron sources, a clinical trial that was carried out by Stenstam, Sköld, Capala and their co-workers in Studsvik, Sweden, using an epithermal neutron beam produced by the Studsvik nuclear reactor, which had greater tissue penetration properties than the thermal beams ...
No cancer therapy is without the risk of side effects. Neutron therapy is a very powerful nuclear scalpel that has to be utilized with exquisite care. For instance, some of the most remarkable cures it has been able to achieve are with cancers of the head and neck. Many of these cancers cannot effectively be treated with other therapies.
Radiation therapy is used to kill cancer cells; however, normal cells are also damaged in the process. Currently, therapeutic doses of radiation can be targeted to tumors with great accuracy using linear accelerators in radiation oncology; however, when irradiating using external beam radiotherapy, the beam will always need to travel through healthy tissue, and the normal liver tissue is very ...
