Chest X-rays use small amounts of ionizing radiation to produce an image of the inside of your lungs. They let doctors visualize how CF is affecting the lungs by performing evaluations for dilated airways containing mucus and lung infections. A chest X-ray will be done every year, or more if needed due to an pulmonary exacerbation. Examples of an exacerbation include increased cough, sputum production, and/or shortness of breath.
Since most x-rays are now digital, the doctor can review results with you before you leave clinic. With this and other testing, antibiotics may be prescribed.
If you have a small child that is unable maintain the correct position, the technician may use a pediatric immobilization device designed for positioning infants and young children for an appropriate x-ray without significant complications. This machine can look intimidating but rest assured that it may be the best option to position your child for their x-ray. It allows the technician to capture the image the first time without repeat radiation exposure.
