X-ray

Last Updated: April 2026

X-ray imaging is the oldest and most widely used form of medical imaging, used to examine nearly every part of the body. It is a quick and painless medical test that helps physicians diagnose and treat a wide range of conditions – from identifying broken bones and locating foreign objects to assisting in the detection of diseases such as cancer. X-rays are a type of electromagnetic radiation, similar to visible light. An X-ray machine is much like a camera, but instead of using light to create images, it uses X-rays to capture detailed views of structures inside the body.

During the exam, a small amount of X-ray energy passes through the body to create an image, called a radiograph. Different tissues, such as bone, fat, muscle, and tumors, absorb X-rays at varying levels. This results in an image with different shades that allow radiologists to distinguish between structures and identify abnormalities. When performed by trained technologists and interpreted by a radiologist, X-ray imaging is considered very safe. The amount of radiation used is minimal, and no radiation remains in the body after the exam.

Types of X-rays

Chest X-rays

A chest X-ray is a quick, noninvasive imaging exam that uses a small amount of radiation to create detailed images of the structures within the chest, including the lungs, heart, ribs, and surrounding tissues. It is one of the most commonly performed diagnostic tests and plays a critical role in evaluating overall chest health.

Your physician may recommend a chest X-ray for a variety of reasons, such as shortness of breath, fever, persistent cough, and chest pain. It is an efficient and effective way to help diagnose a variety of conditions, including pneumonia, COVID-19, lung cancer, tuberculosis, lung disease, abnormalities in heart size, and fractures of the ribs or spine.

During the exam, you will typically stand in front of the X-ray machine and face forward while the image is taken. In many cases, a second image is obtained from the side (lateral view) to provide a more complete evaluation.

The technologist will ask you to take a deep breath and hold it for a few seconds while the image is captured. Remaining still during this time is important, as movement can cause the image to appear blurry. The entire procedure is fast, usually completed within minutes, and you can resume normal activities immediately afterward.

Abdominal X-rays

An abdominal X-ray is a simple, noninvasive imaging exam used to evaluate the organs and structures within the abdomen, including the stomach, small and large intestines, and liver. It is often one of the first tests performed when a patient is experiencing symptoms such as nausea, vomiting, abdominal pain, or swelling.

During this X-ray, the patient lies flat on a table with the X-ray machine placed over their abdomen. Images are captured with the breath held. Based on the patient’s symptoms, additional X-rays may be taken from the side or in a standing position.

Kidney, Ureter, and Bladder X-ray

Also called KUB X-rays, this test is performed to evaluate the abdominal area to determine the possible causes of abdominal pain, or to assess the organs and structures of the urinary and/or gastrointestinal (GI) system. This X-ray is usually the initial step for diagnosing a urinary condition.
With this kind of X-ray, the radiologist may assess the urinary tract, kidneys, ureters, and bladder and will be able to identify whether there are kidney or ureteral stones.

Neck X-ray

A neck X-ray, also known as a cervical spine X-ray, is a quick and noninvasive imaging exam used to evaluate the bones of the neck, known as the cervical spine. It is commonly recommended for patients experiencing persistent neck pain, weakness, or numbness.

During the exam, you may be asked to sit or stand while the X-ray images are taken. The technologist may position your head and neck at different angles to capture multiple views. It is important to remain still while imaging to ensure clear and accurate results. The procedure is fast, painless, and typically completed within minutes, allowing you to return to your normal activities right away.

Hand X-ray

A hand X-ray is recommended for pain in the hand or an injury to the area. It helps identify broken bones, joint abnormalities, bone tumors, or conditions such as infection, arthritis, or tendinitis.

Joint X-ray

A joint X-ray is recommended to examine issues with the knees, shoulders, hips, ankles, or wrists. Patients suspected of arthritis, fractures, inflammation, and numerous other conditions such as gout, osteoarthritis, or rheumatoid arthritis will usually undergo this test.

Skull X-ray

For head injuries or skull-related conditions, a skull X-ray is conducted to help visualize the bones of the head , including facial bones and cranial bones. It can help identify conditions such as tumors, sinus or ear infections, fractures, bone loss, or changes in soft tissue. Additional tests such as MRI with susceptibility-weighted imaging (SWI) may be performed in the case of traumatic brain injury following an accident.

Digital X-ray imaging remains one of the fastest, safest, and most widely used diagnostic tools in modern medicine. It delivers high-quality images in just minutes while using minimal radiation, helping physicians quickly diagnose and treat a wide range of conditions.

Frequently Asked Questions (FAQS)

How long does an X-ray exam take?

Most digital X-ray procedures take just 5–15 minutes from start to finish. You’ll be in and out quickly, making it one of the most convenient imaging options available.

Are X-rays safe?

Yes. When performed by trained radiologists and technologists, digital X-rays use very low doses of radiation. The benefits of accurate diagnosis far outweigh the minimal risk, and no radiation remains in your body afterward. Learn more about radiation safety.

Do I need to prepare for my X-ray?

Preparation is usually minimal. You may be asked to remove jewelry or change into a gown. For most exams, you can eat and drink normally beforehand. Learn more about preparation.

Can I get an X-ray if I’m pregnant?

If you are pregnant or think you may be pregnant, it’s important to inform our team before your exam.

X-rays are generally avoided during pregnancy because they use a small amount of radiation. However, your physician and our imaging professionals will carefully evaluate your situation and determine the safest approach for you and your baby.

When appropriate, alternative imaging methods—such as ultrasound or MRI—may be recommended, as they do not use ionizing radiation.

Your safety is always our top priority, and our team is committed to ensuring you receive the most appropriate and safest care possible.

How soon will I get my results?

A board-certified radiologist will review your images promptly. Results are typically sent to your referring physician within 24–48 hours, and many Akumin locations offer same-day reporting for urgent cases.
