What is Radiologic Technology?

Radiologic technology is the field concerned with the use of radiation, such as X-rays, to diagnose and treat diseases. It is also known as medical imaging or radiography.

Professionals in this field are called radiologic technologists or radiographers, and they specialize in using imaging technology to help physicians image the body and diagnose or treat diseases. 

Radiographers both capture these images and analyze them to identify issues.They are responsible for explaining procedures, positioning patients, using and maintaining equipment, implementing radiation protection measures, and assessing image quality.

Roles of Radiologic Technologists

What do radiologic technologists actually do on a daily basis? Their main roles involve the following:

Operate equipment to image areas of the body

They are responsible for appropriately positioning patients and equipment to image specific areas of interest in the body.

This requires both technical skills in selecting imaging parameters and protocols and patient care skills to properly position patients while explaining what will happen in the exam.

They also strictly follow radiation safety principles, like collimating X-ray beams and using shielding to minimize radiation exposure.

Perform diagnostic imaging examinations like x-rays, CT scans, and MRIs

During imaging procedures like CT scans or X-rays, techs give instructions to patients, monitor the imaging process, and check that quality images are obtained.

They may administer contrast agents to patients when needed to enhance visualization of internal structures for the radiologist.

Radtechs also assist physicians with special procedures like fluoroscopy, which uses a continuous or pulsed X-ray beam to view motion inside the body. Common fluoro procedures include upper GI imaging, arthrograms, myelograms, cystograms, and barium enemas.

Radtechs prepare the contrast agents, operate the fluoro equipment, and assist the radiologist during the exam.

Assist radiologists and other physicians in fluoroscopy, interventional radiography, and other procedures

Interventional procedures are another key duty, which involves guiding and imaging small instruments or devices within the body, such as stents, tubes, balloons, biopsy needles, or catheters.

Radtechs maintain sterile fields, monitor patients, and use fluoroscopic, CT, ultrasound, or MRI guidance during the procedures.

Provide patient care before, during, and after imaging procedures

Lastly, radiologic techs provide a range of direct patient care services throughout imaging exams. This includes explaining procedures, answering questions and concerns, monitoring health status, managing medications or IVs, caring for incisions or drainage tubes after procedures, and checking for adverse reactions. Their patients can feel quite anxious about undergoing imaging tests, so calm and kind reassurance is vital.

Educational Requirements

If a career as a radiologic technologist interests you, what education do you need? You would need to earn an associate’s or bachelor’s degree in the field of radiologic technology or radiography.

This would involve completing a 12-24 month accredited program in radiography. You would receive a combination of classroom education in areas like anatomy, pathology, radiation physics, imaging procedures, patient care, and safety protocols, as well as extensive clinical experience in a healthcare setting working with real patients.

Upon finishing your degree, you would then be eligible to take and pass certification examinations from the American Registry of Radiologic Technologists (ARRT) to receive your official credentials as a Registered Technologist (RT).

Types of Radiologic Equipment

Radiologic technologists operate and assist with a variety of fascinating equipment using radiation, magnetism, and soundwaves to see inside the human body. The main specialties include basic x-ray machines, CT scanners, MRI scanners, ultrasound machines, and mammography units.

Basic x-ray

Most people are familiar with general radiographic x-ray units – the oldest and still most common diagnostic imaging technique.

They consist of a tube emitting a focused X-ray beam that penetrates the body’s tissues and a detector that captures the resulting black-and-white radiographic image.

Studies like chest X-rays, abdomen films, bone scans, and joint X-rays are routine exams. Portable machines on wheelable carts are also used at patient bedsides.

CT or CAT scans

CT scanners have a rotating X-ray tube and detectors arranged in a complete circle or “doughnut” shape. The X-ray beam moves around the patient, shooting through cross-sectional “slices,” which a computer then processes into detailed 3D images. CT is excellent for viewing organs, bones, soft tissue abnormalities, trauma, cancers, and blood vessels.

MRI scans

Instead of radiation, MRI scanners utilize very strong magnetic fields and radio waves to re-align hydrogen atoms within bodily tissues. Detectors sense the signals emitted during realignment, and a computer constructs intricate images. MRI gives unparalleled soft tissue contrast for spinal, joint, neurological, tumor, and certain heart issues.


Ultrasound imaging uses high-frequency sound waves emitted from a handheld probe placed against the skin. The sound waves penetrate tissues, and any reflections bounce back to produce real-time images showing the structure and movement of organs and vessels. Obstetric, cardiac, abdominal, pelvic, and vascular exams utilize ultrasound technology.


Lastly, mammography units are specialized low-dose X-ray systems just for breast imaging. They consist of paddles compressing the breast tissue to acquire top and side images used for cancer screening and diagnosis.

Of course, many hospitals also have image-processing computers, archives for storage, and networks for transmitting digital images so physicians at multiple locations can access and interpret results.

Career Outlook

If a career using the latest and advanced medical technology appeals to you, radiologic technology offers bright prospects looking towards the future.

Faster than average job growth rate predicted

Job growth for radiologic technologists is actually projected to expand at a faster-than-average rate over the next decade compared to other occupations. There are a few major reasons for spurring increasing demand.

Aging population requiring more imaging procedures

Beyond the pay, being a radiologic technologist offers varied day-to-day work experiences using highly complex machinery found in a few other jobs. Every day of performing imaging studies is different.

Every patient’s condition poses unique challenges. Ongoing innovation means mastering new technologies, such as 3D mammography units. Physicians rely heavily on the high-quality images they produce, making it a meaningful medical profession. 

Competitive salaries with potential specialization

The pay is also favorable compared to other technologist positions available with just an associate’s degree. According to Glassdoor, the median salary for Radiologic Techs in the USA is over $88,850 annually.

With additional specialization in areas like MRI, salaries can reach up to $110,00, especially in large metropolitan hospitals. Even beginning-level hospital positions tend to pay over $50,000 for new graduates of radiography programs.
