Web25 de mar. de 2024 · Positioning. Positioning is the most important of the three. It’s estimated that 85% of all repeat images are due to positioning errors. Most modern X-ray systems come equipped with automatic exposure controls, also known as AECs or AEDs. They are also sometimes referred to as phototiming. Radiocontrast agents are substances used to enhance the visibility of internal structures in X-ray-based imaging techniques such as computed tomography (contrast CT), projectional radiography, and fluoroscopy. Radiocontrast agents are typically iodine, or more rarely barium sulfate. The contrast agents absorb external X-rays, resulting in decreased exposure on the X-ray detector. This is different from radiopharmaceuticals used in nuclear medicine which emit radiation.
