5 Different Types of Radiology Technicians

Radiology technicians, also known as radiologic technologists, specialize in various imaging modalities within the field of radiology. Here are five different types of radiology technicians based on their areas of specialization

Radiologic technologists, often referred to as X-ray technologists, specialize in conventional X-ray imaging. They perform diagnostic imaging examinations, such as chest X-rays, bone studies, and contrast studies, using X-ray equipment. They position patients, adjust the X-ray machine, and ensure proper radiation safety measures are followed.


CT technologists specialize in computed tomography (CT) scans, which use advanced X-ray technology to create detailed cross-sectional images of the body. They prepare and position patients for CT scans, operate the CT scanner, adjust imaging parameters, and ensure proper radiation dose management.


MRI technologists specialize in magnetic resonance imaging (MRI), a non-ionizing imaging modality that uses powerful magnets and radio waves to generate detailed images of the body’s internal structures. They prepare and position patients for MRI scans, operate the MRI scanner, adjust imaging parameters, and ensure patient safety in the magnetic environment.


Nuclear medicine technologists specialize in using small amounts of radioactive materials, known as radiopharmaceuticals, to diagnose or treat various conditions. They prepare and administer radiopharmaceuticals, operate gamma cameras or PET/CT scanners, and process the resulting images to help physicians evaluate the function of organs, diagnose diseases, or monitor treatment response.


Sonographers, also known as ultrasound technologists, specialize in diagnostic medical sonography or ultrasound imaging. They use high-frequency sound waves to create images of the body’s internal structures, such as organs, blood vessels, or developing fetuses. Sonographers may further specialize in areas such as abdominal, obstetric and gynecologic, vascular, or cardiac sonography.

These are just a few examples of the different types of radiology technicians based on their areas of specialization. Some radiologic technologists may also choose to specialize in interventional radiology or radiation therapy, which involve using imaging guidance for minimally invasive procedures or cancer treatment, respectively. Each specialty requires specific training, knowledge, and skills, and may have additional certification requirements.
