X-Rays, the Most Widely Available Diagnostic Imaging Technique

What is an X-ray?

An X-ray is an image of a part of the body created by passing X-ray radiation through the body. X-rays are a type of ionizing radiation which can pass through soft tissues of the body and create an image of the bones inside. When X-rays pass through the body, they interact with atoms inside cells. When they interact with atoms, they lose energy and create an image of the cells. This image allows healthcare providers to see the bones and tissues inside a person’s body. X-rays are a type of electromagnetic radiation. Electromagnetic radiation is energy that travels in waves. The shorter the wavelength of the electromagnetic radiation, the higher its energy content. X-rays have a shorter wavelength than other types of electromagnetic radiation, such as microwaves or radio waves. The shorter wavelength of X-rays means that they have more energy than other waves of electromagnetic radiation. Because X-rays have more energy, they can penetrate tissues and organs in the human body more deeply than other types of radiation. X-rays are used for many diagnostic imaging procedures because they can pass through the body and expose only a small amount of skin to radiation.

How X-rays Work

X-rays are produced by an X-ray machine (also called a “source”). The machine uses a high-powered electron beam that passes through the body and is absorbed by the bone. The beam of X-rays then passes through the body and is captured on film. X-rays create images of the body by passing through soft tissue to harder tissue, such as bone. The X-rays are absorbed by the bone, but not the soft tissue, so an image is created of the bone. The more dense areas such as bone create a white image on the film and areas with less density such as air create a black image on the film. X-rays pass through the body in a straight line. Because X-rays pass through the body in a straight line, they produce a two-dimensional image and don’t show the three-dimensional structure of the body.

Why Are X-rays Used in Healthcare?

X-rays are used to look inside the human body to find out if there are broken bones, if there are foreign objects inside the body, or to find signs of diseases, such as tumors. X-rays are used to diagnose and track the progress of many conditions, including arthritis, fractures, and other bone problems. They can also be used to identify broken or dislocated bones, foreign objects in the body, abnormal growths, and calcification. X-rays can be used to find cancers in their early stages. These cancers are sometimes too small to be seen with other imaging techniques. Earlier diagnosis can result in better outcomes, as the patient has more time to get treatment.

Different Types of X-Ray Imaging

There are different types of x-ray imaging techniques. Computed tomography (CT) scanning uses x-rays to create a detailed 3-dimensional image of the body. Magnetic resonance imaging (MRI) uses a magnetic field to create a detailed image of the body’s soft tissues, bones, and internal organs. X-rays are also used to track the progress of a disease to monitor healing and assess the current health of a patient. X-rays are commonly used as a screening tool to look for certain conditions and diseases. They can be used to find fractures, broken bones, or other problems within the body but they’re not used to diagnose the condition. X-rays are also used to determine the correct dose of radiation that a patient will receive in radiation therapy.

Limitations of X-Rays

X-rays are a useful tool for medical imaging, but there are limitations to their accuracy. X-rays are useful for imaging the bones inside the body and for detecting fractures, but they don’t show much detail about soft tissues, such as muscles, organs, and blood vessels. X-rays can be helpful in detecting early-stage cancers, but they are not as useful for finding slow-growing cancers and aren’t used to diagnose most cancers. X-rays are safe when taken in moderation, but they do expose the patient and the medical staff to low levels of ionizing radiation. X-rays are useful for many medical imaging procedures, but there are other imaging techniques that are better for specific situations.
