Fluoroscopy can result in relatively high radiation doses, especially for complex interventional procedures (such as placing stents or other devices inside the body) which require fluoroscopy be administered for a long period of time. Fluoroscopy - a continuous X-ray image is displayed on a monitor, allowing for real-time monitoring of a procedure or passage of a contrast agent ('dye') through the body.Mammography is a special type of radiography to image the internal structures of breasts. Radiography - a single image is recorded for later evaluation.Ionizing radiation is a form of radiation that has enough energy to potentially cause damage to DNA and may elevate a person's lifetime risk of developing cancer.ĬT, radiography, and fluoroscopy all work on the same basic principle: an X-ray beam is passed through the body where a portion of the X-rays are either absorbed or scattered by the internal structures, and the remaining X-ray pattern is transmitted to a detector (e.g., film or a computer screen) for recording or further processing by a computer. Computed tomography (CT), fluoroscopy, and radiography ('conventional X-ray' including mammography) all use ionizing radiation to generate images of the body. There are many types - or modalities - of medical imaging procedures, each of which uses different technologies and techniques. Medical imaging has led to improvements in the diagnosis and treatment of numerous medical conditions in children and adults.
