What Is Radiography?
What is radiography? Learn about diagnostic and therapeutic radiography, the technology used, qualifications and careers in the UK.
Quick Answer
Radiography is a healthcare profession involving medical imaging or radiotherapy. Diagnostic radiographers produce images to help diagnose conditions, while therapeutic radiographers deliver radiotherapy treatment.
Introduction
Radiography is one of the clearest examples of STEM being applied directly to healthcare. It combines science, technology and patient care, making it an interesting career for students who enjoy subjects such as physics and biology.
What Does a Radiographer Do?
The answer depends on the type of radiography. Diagnostic radiographers perform imaging examinations, while therapeutic radiographers work with patients receiving radiotherapy.
Both careers require technical knowledge, safe practice and strong communication with patients.
Diagnostic Radiography
Diagnostic radiographers use imaging technology to help investigate injury and disease. Their work can include X-ray and, with further training or in appropriate roles, CT and MRI.
Patient care is a major part of the job. A patient may be in pain, anxious or unable to move easily, so the radiographer needs to adapt the examination while maintaining safety and image quality.
Therapeutic Radiography
Therapeutic radiographers work in cancer treatment, delivering radiotherapy as part of a multidisciplinary team.
The role involves technology and treatment planning but also considerable patient support. Patients may attend multiple appointments, meaning therapeutic radiographers can develop ongoing professional relationships with them.
What Science Is Used in Radiography?
Physics is particularly relevant because imaging technologies depend on physical principles. Biology and anatomy are also important because radiographers need to understand the body and the clinical reason for an examination.
Radiography therefore suits students who want to apply classroom science to real healthcare situations.
How Do You Become a Radiographer?
In the UK, students normally complete an approved education programme in diagnostic or therapeutic radiography and then meet the requirements for professional registration.
Course structures and entry requirements vary, so students should check current university and HCPC information.
Why Choose Radiography?
Radiography can be an attractive alternative for students interested in medical imaging but who do not want to follow the medical degree pathway.
It combines practical technology, science and patient contact and can provide opportunities to develop specialist skills.
- Apply science in a healthcare setting
- Work with advanced medical technology
- Have regular patient contact
- Develop specialist imaging or treatment skills
- Build a healthcare career without becoming a doctor
Radiography vs Radiology
Area | Radiography | Radiology |
Profession | Healthcare profession | Medical specialty |
Practitioner | Radiographer | Doctor/radiologist |
Diagnostic work | Performs many imaging examinations | Interprets imaging |
Therapeutic work | Delivers radiotherapy | May be involved in image-guided procedures depending on specialty |
Main strengths | Technology + practical patient care | Medicine + imaging interpretation |
Conclusion
Radiography is a technology-focused healthcare career that combines science with practical patient care. Diagnostic radiography focuses on medical imaging, while therapeutic radiography focuses on radiotherapy. It is worth exploring alongside radiology because it offers a different route into medical imaging without requiring a medical degree.
Frequently Asked Questions
Is radiography a STEM career?
Yes. It combines science, technology, anatomy and healthcare.
Do radiographers use physics?
Yes. Physics underpins many of the technologies used in imaging and radiotherapy.
Is radiography the same as radiology?
No. They are separate professions with different training routes.
Can radiographers use MRI and CT?
Some diagnostic radiographers work with CT and MRI depending on their role, training and workplace.
