World Radiography Day: the important role of radiographers


NOVEMBER 8 is of great significance in the X-ray industry.

It’s the day that marks the invention of X-rays by Wilhelm Roentgen, dating back to 1895 in Germany, and the technology that has saved billions of lives around the world since then.

The theme of this year’s World Radiography Day is, “Radiographers at the forefront of patient safety”as an appreciation of the role played by radiographers or radiological technologies in promoting and preserving radiation protection and general patient safety.

The scope of radiological medicine has expanded considerably over the past 50 years, with the birth of three specialties, namely diagnostic radiology, therapeutic radiology and nuclear medicine radiology.

Diagnostic radiology

Diagnostic radiology is a medical process that involves undertaking a range of imaging procedures to obtain images of the inside of the body. The diagnostic radiologist then carefully interprets these images to diagnose disease and injury. Interpretations of these images help create a niche for the kind of medical assistance needed.

Diagnostic radiology itself breaks down into different spheres, namely simple radiology (X-rays), computed tomography (CT Scan), magnetic resonance imaging (MRI), ultrasound (also called sonographic examination) and nuclear medicine imaging techniques.

Therapeutic radiology

Therapeutic radiology is also known as radiation therapy or radiation oncology, which is the use of radiation to treat cancer and other tissue diseases. Radiation in many forms is used to kill or prevent cancer cells from multiplying. This type of radiation can be used to cure or control cancer or can be used to alleviate some of the symptoms related to cancer.

Radiology in nuclear medicine

This type of radiology involves the use of very small amounts of radioactive materials, or radiopharmaceuticals, to examine the function and structure of organs.

Due to its complexity, nuclear medicine is a combination of many different elements, including mathematics, physics, chemistry, computer science, and medicine. This branch of radiology is often used to diagnose and treat abnormalities very early in the progression of a disease such as thyroid cancer.
