MEDICAL ANIMATION TRANSCRIPT: X-ray images are like photos of the inside of your body. But X-ray videos can be made as well. They're made during a procedure called fluoroscopy. One reason your doctor may give you a fluoroscopy exam is to find out if you have certain diseases, such as problems in your digestive tract. A second reason your doctor may use fluoroscopy is to perform a procedure such as a spinal tap. A third reason is to find, locate, and identify a foreign object in your body. There are several types of fluoroscopy machines. A fluoroscope may be fixed in place in a special shielded room. Or it may be a portable machine that can be moved to you if needed. A computed tomography, or CT scan machine can also be used as a fluoroscope to see slices through the body as the images are taken. Before a fluoroscopy procedure, you may be given a contrast substance. It may be in a drink, a paste, a pill, or an injection. During the procedure, you will lie or stand on an X-ray table. An X-ray tube will be aimed at the body part to be examined. Then an X-ray beam will pass through a part of the fluoroscope that shapes the beam to just the area of your body being studied. This helps reduce your exposure to X-rays. After the beam passes through your body, it will be converted into a video seen on a monitor screen. If you receive a contrast substance, it will make the structure stand out better on the screen. If you have any questions about fluoroscopy, talk to your doctor.
