When used for viewing images in real time (called fluoroscopy), the image intensifier (which converts x-rays into a video image) is suspended over a table on which the patient lies. The equipment typically used for this examination consists of a radiographic table, an x-ray tube and a television-like monitor that is located in the examining room or in a nearby room. You may also be asked to remove jewelry, eye glasses and any metal objects or clothing that might interfere with the x-ray images. You may be asked to remove some or all of your clothes and to wear a gown during the exam.
Therefore, you will likely be asked not to eat or drink anything (including any medications taken by mouth, especially antacids) and to refrain from chewing gum and smoking after midnight on the day of the examination. To ensure the best possible image quality, your stomach must be empty of food. If an x-ray is necessary, precautions will be taken to minimize radiation exposure to the baby. Many imaging tests are not performed during pregnancy so as not to expose the fetus to radiation. Women should always inform their physician or x-ray technologist if there is any possibility that they are pregnant. Also inform your doctor about recent illnesses or other medical conditions. You should inform your physician of any medications you are taking and if you have any allergies, especially to barium or iodinated contrast materials.
X-rays are the oldest and most frequently used form of medical imaging.įluoroscopy makes it possible to see internal organs in motion. Imaging with x-rays involves exposing a part of the body to a small dose of ionizing radiation to produce pictures of the inside of the body. A Swallow Study is an x-ray examination of the pharynx, and esophagus that uses a special form of x-ray called fluoroscopy and an orally ingested contrast material called barium or gastroview.Īn x-ray (radiograph) is a noninvasive medical test that helps physicians diagnose and treat medical conditions.
