It is important to explain the basic aspects of each medical radiation science profession: Radiation Therapy, Nuclear Medicine Technology and Medical Imaging.
What are their similarities? And what differences do they have?
Professions in Medical Radiation Science
Medical radiation science includes a variety of complex imaging diagnosis and planning of radiation treatments for patients suffering from various types of cancers.
These careers include radiation therapy, nuclear medicine technology, and medical imaging (Roobottom Mitchell and Hughes 2010).
While the professionals in nuclear medicine technology and medical imaging work in hospitals, imaging clinics, and clinics, radiation therapists work in cancer centers and clinics.
Medical imaging can include X-rays, ultrasound, radionuclides (SPECT and PET), magnetic resonance and planar and CT Xrays.
X-rays use ionizing radiation if there is an external source.
Magnetic resonance, however, uses magnetic fields and radiofrequency waves to create anatomical images.
Ultrasound imaging, which can be described as a core element, uses frequency sound waves in conjunction with echo pulse effects to generate anatomical information.
Nuclear medicine is the use radioactive isotopes. These are emitters of gamma-rays and similar ionizing substances.
The radionuclide can be injected or inhaled, and then the radiation is picked up by the Gamma Camera.
This radioactivity is used in the production and processing of functional images.
Radiation therapy employs high-frequency waves and energy particles like the X-rays and electron beams or protons to destroy and kill cancer cells (Xu & Tsui (2014)
There are similarities between medical imaging, nuclear medicine technology and radiation therapy. They all use non-invasive techniques or methods to study inside a body without having to open it up surgically.
They use various techniques, such as radionuclide (SPECT or PET), ultrasonography and magnetic resonance imaging to treat different diseases and conditions of the human body (Rivaz Boctor, Choti, Hager and Choti 2014).
There are differences between the medical science radiation professions. The image qualities created by the different methods can differ in terms of resolution and contrast.
The radiation therapy, medical imaging and nuclear radiation may have different effects on the body, due to the heating effect and the ionization radiation effect.
To sum it, medical imaging is used in order to obtain diagnostic images. Nuclear medical technology is used by radiotherapy to treat patients with cancer.
All of these medical radiation science professions are aimed at improving the health and well-being of patients by offering non-surgical treatment options.
They have also helped to improve the quality and quantity of life around the globe.
