Encyclopedia > Radiologic technologist

A radiologic technologist (also called a radiographer ) is a person who uses ionizing radiation to create medical images of the body to help diagnose and treat illness and injury. They work in hospitals, clinics, medical laboratories, nursing homes, and in private industry. Radiation hazard symbol. ...

Nature of work

Diagnostic radiologic technologists employ a range of sophisticated equipment to produce high quality images to diagnose an injury or disease. They use a range of techniques including:

  • X-rays– to look through tissue to examine bones, cavities and foreign objects;
  • Ultrasound – uses high frequency sound and is increasingly used due to its versatility in obstetrics, including fetal monitoring throughout pregnancy, gynaecology, abdominal, paediatrics, cardiac, vascular and musculo-skeletal;
  • Fluoroscopy – live motion X-ray (constant radiation) usually used to image the digestive system;
  • CT (computed tomography) – which provides cross-sectional views (slices) of the body;
  • MRI (magnetic resonance imaging) – builds a 2-D or 3-D map of different tissue types within the body;
  • Nuclear medicine – this uses radioactive tracers which can be administered to examine how the body and organs function, for example the kidneys or heart. Certain radioisotopes can also be administered to treat particular cancers eg thyroid

In the NATO phonetic alphabet, X-ray represents the letter X. An X-ray picture (radiograph) taken by Röntgen An X-ray is a form of electromagnetic radiation with a wavelength approximately in the range of 5 pm to 10 nanometers (corresponding to frequencies in the range 30 PHz...

Education

The education of a radiologic technologist varies worldwide. Usually their educational qualifications may include a diploma after secondary schooling or a three year to four year bachelor's degree or master's degree. Formal training programs in radiography range in length from 1 to 4 years and lead to a certificate, an associate degree, or a bachelor’s degree. Two-year associate degree programs are most revalent. Since these professionals are using ionizing radiation, which is potentially harmful to the living cells, most countries have strict regulations and certifications regarding the practice of this profession.


The educational curriculum also varies in different countries. Usually during their formal education they must learn human anatomy and physiology, general and nuclear physics, mathematics, radiation physics, pathology, medical imaging sciences and diagnosis, radiologic instrumentation, radio diagnosis, and photographic imaging techniques and chemistry.

Pathology (from Greek pathos, feeling, pain, suffering; and logos, study of; see also -ology) is the study of the processes underlying disease and other forms of illness, harmful abnormality, or dysfunction. ... Medical imaging designates the ensemble of techniques and processes used to create images of the human body (or parts thereof) for clinical purposes (medical procedures seeking to reveal, diagnose or examine disease) or medical science (including the study of normal anatomy and function). ...


This is a blend of medical sciences and physical sciences.


Radiologic technologist in the U.S

A radiologic technologist in the U.S. goes to school for at least 2 years, unless their state allows a 4 week education program for a limited license, through a program accredited by the American Registry of Radiologic Technologists (ARRT) or through an accredited military program such as the US ARMY MOS 91P and then must pass a written examination, as well as final exams at the place of their clinical education . The American Registry of Radiologic Technologists (ARRT) is a national registry for individuals with degrees in the field of diagnostic medical Radiography, Radiation therapy and Nuclear Medicine, amongst other subspecialties. ...


ARRT registration is necessary to operate medical X-ray equipment in the United States except in the cases of dental and veterinary imaging.


Federal legislation protects the public from the hazards of unnecessary exposure to medical and dental radiation by ensuring that operators of radiologic equipment are properly trained. Under this legislation, the federal government sets voluntary standards that the States may use for accrediting training programs and certifying individuals who engage in medical or dental radiography.


In 2005, 38 States certify radiologic technologists and technicians. Certification, which is voluntary, is offered by the American Registry of Radiologic Technologists. To be eligible for certification, technologists generally must graduate from an accredited program and pass an examination. Many employers prefer to hire certified radiographers. To be recertified, radiographers must complete 24 hours of continuing education every two years.


Radiologic technologists in The U.K

Radiologic technologists in The U.K usually known as diagnostic radiographers. The title, diagnostic radiographer is a protected title by law. And the qualified candidate has to register with the Health Professions council. Although radiographers who qualified before 1990 can still maintain their licence with the diploma in diagnostic radiography, all radiographers post 1990 must have obtained a bachelors degree in diagnostic radiography to obtain their licence from the Health Professionals Council (HPC). Radiographers are also required to continue their education to maintain this licence (as all healthcare professionals such as nurses are required to do)


In the NHS Radiographers are now undertaking many of the roles historically undertaken by radiologists (Doctors specialising in medical imaging) such as reporting on films and the performing of procedures such as barium enemas. Radiology is the branch of medical science dealing with the medical use of x-ray machines or other such radiation devices for the purpose of obtaining visual information as part of medical imaging. ...


Professional advancement

With experience and additional training, staff technologists may become specialists, performing CT scanning, angiography, and magnetic resonance imaging. Experienced technologists also may be promoted to supervisor, chief or lead radiologic technologist, and, ultimately, department administrator or director. Depending on the institution, courses or a master’s degree in business or health administration may be necessary for the director’s position.


Some technologists progress by leaving the occupation to become instructors or directors in radiologic technology programs; others take jobs as sales representatives or instructors with equipment manufacturers.



Other imaging modalities such as mammography, ultrasound (sonography), nuclear medicine, MRI and CT scanning may be performed by a radiologic technologist, but only one who has further training and/or accredation from the basic levels. (the results of a pilot study on using sonography as a primary certification was published by the ARRT in 2005).[1] Mammography. ... Medical ultrasonography (sonography) is an ultrasound-based diagnostic imaging technique used to visualize muscles and internal organs, their size, structures and possible pathologies or lesions. ...

Some ultrasound and MRI technologists are not radiologic technologists. They are able to perform exams specifically and solely in these areas because these modalities don't use ionizing radiation.
