Discuss the fees associated with your prescribed procedure with your doctor, the medical facility staff and/or your insurance provider to get a better understanding of the possible charges you will incur. The costs for specific medical imaging tests, treatments and procedures may vary by geographic region. This website does not provide cost information. To locate a medical imaging or radiation oncology provider in your community, you can search the ACR-accredited facilities database. Please contact your physician with specific medical questions or for a referral to a radiologist or other physician. This ensures that the areas of your body not being imaged receive minimal radiation exposure. Modern x-ray systems minimize stray (scatter) radiation by using controlled x-ray beams and dose control methods. National and international radiology protection organizations continually review and update the technique standards radiology professionals use. See the Radiation Safety page for more information about pregnancy and x-rays.Ī Word About Minimizing Radiation Exposureĭoctors take special care during x-ray exams to use the lowest radiation dose possible while producing the best images for evaluation. Women should always tell their doctor and x-ray technologist if they are pregnant.See the Radiation Dose page for more information. The radiation dose for this procedure varies.However, given the small amount of radiation used in medical imaging, the benefit of an accurate diagnosis far outweighs the associated risk. There is always a slight chance of cancer from excessive exposure to radiation.Because x-ray imaging is fast and easy, it is particularly useful in emergency diagnosis and treatment.This makes it convenient for both patients and doctors. X-ray equipment is relatively inexpensive and widely available in emergency rooms, doctors’ offices, ambulatory care centers, nursing homes, and other locations.X-rays usually have no side effects in the typical diagnostic range for this exam.No radiation stays in your body after an x-ray exam.The entire chest x-ray examination, from positioning to obtaining and verifying the images, is usually completed within 15 minutes.Īdditional views may be required within hours, days or months to evaluate any changes in the chest. When the examination is complete, the technologist may ask you to wait until the radiologist confirms they have all the necessary images. The technologist will walk behind a wall or into the next room to activate the x-ray machine. This helps reduce the possibility of a blurred image. ![]() You must hold very still and may need to hold your breath for a few seconds while the technologist takes the x-ray. Patients who cannot stand may be positioned lying down on a table for chest x-rays. For the second view, the patient's side is against the image plate with arms elevated. The technologist, an individual specially trained to perform radiology examinations, will position the patient with hands on hips and chest pressed against the image plate. Typically, two views of the chest are taken, one from the back and the other from the side of the body as the patient stands against the image recording plate. Your doctor can easily access these stored images to diagnose and manage your condition. Most x-ray images are electronically stored digital files. Lung tissue absorbs little radiation and will appear dark on the image. On a chest x-ray, the ribs and spine will absorb much of the radiation and appear white or light gray on the image. As a result, bones appear white on the x-ray, soft tissue shows up in shades of gray, and air appears black. Dense bone absorbs much of the radiation while soft tissue (muscle, fat, and organs) allow more of the x-rays to pass through them. The radiation records an image on photographic film or a special detector.ĭifferent parts of the body absorb the x-rays in varying degrees. The machine produces a small burst of radiation that passes through your body. The technologist carefully aims the x-ray beam at the area of interest. X-rays pass through most objects, including the body. X-rays are a form of radiation like light or radio waves. ![]()
