Radiology is a branch of science that deals with the medical use of X-rays or other penetrating radiation. This particular branch or specialty of medicine deals with not only the study, but also with the application of imaging technology like x-ray and radiation. Radiology is used for diagnosing and treating disease, ultrasounds, and nuclear medicine just to name a few. There are four main types of radiology: diagnostic, interventional, nuclear medicine and radiation therapy. The professional that operates the radiology machines is known as a radiologist. A radiologist is responsible for directing an array of imaging technologies, often times using Interventional radiology. Interventional radiology is the performance of medical procedures with the guidance of imaging technologies. However, the radiographer is usually the one who carries out the medical imaging. Outside of the medical field, radiology encompasses the examination of the inner structure of objects using x-rays and/or other penetrating radiation.


  • Doctors check the various systems of the body to determine if anything is wrong
  • Best health prevention method, aside from the standard healthy diet and exercise
  • Radiological methods can be used within three hours of a person's stroke symptoms
  • Angioplasty
  • Live longer


Radiologlist is a medical specialty of a phyiscian or a surgeon. Thei typical job discription includes:
  • Diagnose diseases through the use of radiology examinations (ex. x-rays, ultrasounds, MRIs)
  • Handle patient records
  • Recommend treatments to patients

Radiologist phyisicians job lookout is expected to row 26% between 2010-2020
The median annual wage of a Radiologist Physician is $388,237

Radiologic technologists are those that perform the procedures of radiology examinations. Their typical job discription includes:
  • Adjust and maintain imaging equipment
  • Presicely follow orders from physicians on what areas of the body to image
  • Prepare patients for procedures, including taking a medical history and answering questions about the procedure
  • Protect the patient by shielding exposed areas that do not need to be imaged
  • Position the patient and the equipment in the location needed to get the correct image
  • Operate the computerized equipment to take the images
  • Work with radiologists reading the images to determine whether other images need to be taken
  • Keep detailed records

Radiologic technologist job outlook is expected to grow 28% between 2010-2020.
The median annual wage of rodiologic techologists was $54,340 in May 2010.
To become a Radiologic Technologist you must become certified by the state or from The American Registry of Radiologic Technologist (ARRT).
