![]() ![]() Fluoroscopy allows your doctor to view joints or internal organs in motion. Your exam may use a contrast material to clearly define the area of interest. Your doctor can easily access these stored images to diagnose and manage your condition.įluoroscopy uses a continuous or pulsed x-ray beam to create images and project them onto a video monitor. Most x-ray images are electronically stored digital files. 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.Äifferent 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. The technologist will be able to hear and talk to you using a speaker and microphone. This is where the technologist operates the scanner and monitors your exam in direct visual contact. The computer workstation that processes the imaging information is in a separate control room. ![]() Rotating around you, the x-ray tube and electronic x-ray detectors are located opposite each other in a ring, called a gantry. You will lie on a narrow table that slides in and out of this short tunnel. The CT scanner is typically a large, donut-shaped machine with a short tunnel in the center. ![]() This procedure may use other equipment, including an intravenous line (IV), ultrasound machine and devices that monitor your heart beat and blood pressure. The x-ray machine and a detector suspended over the exam table produce the video. ![]() Doctors use it to watch and guide procedures. Fluoroscopy converts x-rays into video images. This exam typically uses a radiographic table, one or two x-ray tubes, and a video monitor. If you have not already provided your radiologist with prior relevant imaging exams (e.g., MRI of lumbar spine), bring them with you on the day of your procedure. See the Safety in X-ray, Interventional Radiology and Nuclear Medicine Procedures page for more information about pregnancy and x-rays. If an x-ray is necessary, the doctor will take precautions to minimize radiation exposure to the baby. Doctors will not perform many tests during pregnancy to avoid exposing the fetus to radiation. Women should always tell their doctor and technologist The nurse will give you a gown to wear during the procedure. Plan to have someone drive you home after your procedure. Your doctor will tell you which medications you may take in the morning. Your doctor will likely tell you not to eat or drink anything after midnight before your procedure. Tell your doctor about recent illnesses or other medical conditions. Your doctor may tell you to stop taking aspirin, nonsteroidal anti-inflammatory drugs ( NSAIDs) or blood thinners before your procedure. List any allergies, especially to local anesthetic, Tell your doctor about all the medications you take, including herbal supplements. Prior to your procedure, your doctor may test your blood to check your kidney function and to determine if your blood clots normally. ![]()
