Radiology technologists take x-rays, perform fluoroscopy and administer various materials into patients' bloodstreams for diagnostic purposes. Some technologists specialize in diagnostic imaging technologies, such as computerized tomography (CT) and magnetic resonance imaging (MRI). Radiologic technologists and technicians, also referred to as radiographers , produce xray films (radiographs) of parts of the human body for use by radiologists and other physicians in diagnosing medical problems.

They prepare patients for radiology exams by explaining the radiographic procedure, removing articles through which xrays cannot pass and positioning patients so that the parts of the body can be appropriately radiographed.To prevent unnecessary radiation exposure, these workers surround the exposed area with radiation protection devices, such as lead shields, or limit the size of the xray beam with collimation.

Radiology technologists position radiographic equipment at the correct angle and height over the appropriate area of a patient's body. Using instruments similar to a measuring tape, they may measure the thickness of the section to be radiographed and set controls on the xray machine to produce radiographs of the appropriate density, detail, and contrast. They place the x ray film under the part of the patient's body to be examined and make the exposure. They then remove the film and develop it.

Diagnostic medical sonographers, also known as ultrasonographers , use special equipment to direct nonionizing, high frequency sound waves into areas of the patient's body. Sonographers operate the equipment, which collects reflected echoes and forms an image that may be videotaped, transmitted, or photographed for interpretation and diagnosis by a physician.

Sonographers begin by explaining the procedure to the patient and recording any medical history that may be relevant to the condition being viewed. They then select appropriate equipment settings and direct the patient into positions that will provide the best view.

To perform the exam, sonographers use a transducer, which transmits sound waves in a cone- or rectangle-shaped beam. Although techniques vary with the area being examined, sonographers usually spread a special gel on the skin to aid the transmission of sound waves. Viewing the screen during the scan, sonographers look for subtle visual cues that contrast healthy areas with unhealthy ones. They decide whether the images are satisfactory for diagnostic purposes and select which ones to show to the physician.


Nuclear medicine technologists operate cameras that detect and map the radioactive drug in a patient's body to create diagnostic images. After explaining test procedures to patients, technologists prepare a dosage of the radiopharmaceutical and administer it by mouth, injection, or other means.

They position patients and start a gamma scintillation camera, or "scanner," which creates images of the distribution of a radiopharmaceutical as it localizes in, and emits signals from, the patient's body. The images are then displayed on a computer screen or on film for a physician to interpret.

When preparing the radiopharmaceuticals, nuclear medicine technologists adhere to safety standards that keep the radiation dose to workers and patients as low as possible. Technologists keep patient records and record the amount and type of radionuclides received, used, and discarded.


Diagnostic Medical Imaging schools have one thing in common: they are difficult to complete! Imagine the amount of diagnostic medical imaging information you must learn to earn the diagnostic medical imaging degree you desire. You'll have no time for fun!

Luckily there are many online diagnostic medical imaging resources that will help you digest and understand the information taught by those old rad techs turned bone densitometry college professors. The problem is that this information can be hard to find because of the enormous amount of diagnostic medical imaging links out there on the world wide web.

That's why we make diagnostic medical imaging schools easier by pulling together the best online diagnostic medical imaging student resources into a convenient location. Here you will find original content as well as excellent links to other sites that will help you on your way to becoming a radiology technologist, computed tomography technologist, mri technologist , nuclear medicine technologist, interventional radiology technologist or ultrasound.
