X-rays

What are X-ray tests?

A basic X-ray image can provide valuable information, such as detecting bone fractures or lung abnormalities.

Advanced X-ray techniques can also investigate issues with the body's soft tissues. Injecting special dye into arteries or veins can make blood vessels visible. Swallowing special dye allows examination of the esophagus and stomach, while similar dye introduced via an enema can assess the rectum and large bowel.

CT scanning, a further advancement, utilizes a sophisticated scanner connected to a computer to produce cross-sectional images of the living body.

What happens during an X-ray test?

X-rays are generated by an electrical machine, with the patient positioned between the machine and a special screen for image capture. Patients are instructed to remove any metallic objects that may interfere with the image. They are asked to remain still for each brief image capture, as the procedure is painless with no side effects. Images are reviewed for technical quality by a radiographer and then sent to a radiologist for interpretation.

For more intricate examinations, the process may take a few hours before the official results are available.

Is X-ray radiation hazardous?

X-rays possess a dual nature in radiology—they can cause cancer and be used to treat it. With modern techniques employing minimal radiation doses for high-quality images, the risk of cancer from X-ray exams under proper supervision is exceedingly low, almost negligible.

Radiographers, who work routinely with X-rays, take precautions to minimize their radiation exposure. Pregnant women are advised to limit X-ray exposure to the absolute minimum due to potential harm to the fetus. Any pregnant woman undergoing an X-ray should inform the radiographers and attending doctors of her condition.

Who are radiographers?

Radiographers are trained professionals responsible for operating X-ray equipment and caring for patients during radiological exams or treatment. Those operating equipment for diagnostic purposes are called diagnostic radiographers, while those involved in treatment are known as therapy radiographers.

Who is a radiologist?

A radiologist is a qualified physician specializing in interpreting X-ray images and performing investigations and treatments reliant on imaging techniques.

Who is a radiotherapist?

A radiotherapist, also known as a clinical oncologist, is a doctor specializing in disease treatment using X-rays and/or cytotoxic medications.
