Plain X-rays are one of the most common diagnostic procedures in healthcare. They are primarily used to visualize and assess bones and other internal structures of the body to detect fractures, infections, and other conditions. For more in-depth information on X-rays and the professionals involved, refer to the introductory page. Please note that this article covers ‘plain’ X-ray imaging and not fluoroscopy; refer to the Fluoroscopy FAQs for details on fluoroscopic procedures.

Curious about your upcoming radiology exam? This post provides clear, patient-friendly information to help you understand what to expect, how to prepare, and what your results might mean.
Introduction
Frequently Asked Questions
What is an X-ray?
X-rays are invisible energy waves that can pass through your body to create images of your internal structures, helping doctors understand what’s going on inside. Given their energy and the possible risks, X-rays are expected to only be done as indicated by a doctor.
What is Plain X-ray imaging, and how is it different from Fluoroscopy?
Plain X-ray imaging, also known as conventional or static X-ray imaging, captures still images of your body. To make it more relatable, this means X-ray images are like a static photographic image. Fluoroscopy, on the other hand, provides real-time images. For more on fluoroscopy, check the Fluoroscopy FAQs.
Why is an X-ray required?
There are several reasons for which X-rays can be requested. Your doctor is therefore in the best position to answer this question. However, common reasons for X-ray investigations may include fractures, infections, bone abnormalities, and abdominal swelling.
How are X-rays named?
X-rays are mostly named based on the area being examined. For example, a Chest X-ray looks at the Chest, an Abdominal X-ray focuses on the Abdomen, and a Foot X-ray shows your Foot.
Note: One common assumption is that a single X-ray image can show every part of the body. This is not correct. X-rays are designed and carried out in such a way that the X-ray energy is only focused on the area of interest (described as Collimation).
How does Plain X-ray work?
An X-ray machine directs a controlled amount of radiation through the body, creating an image on a X-ray detector or X-ray plate. Different body parts of your body absorb the radiation differently, allowing a radiologist to interpret the resulting image.
How does an X-ray test feel?
X-ray tests are painless. You might experience slight discomforts while the Radiographer positions you, but this typically lasts for only a few seconds.
