Imaging with contrast
A contrast agent (or contrast medium) is a substance used to increase the contrast of structures or fluids within the body in medical imaging. Contrast agents absorb or alter external electromagnetism or ultrasound, which is different from radiopharmaceuticals, which emit radiation themselves. In x-ray imaging, contrast agents enhance the radiodensity in a target tissue or structure. In magnetic resonance imaging, contrast agents shorten (or in some instances increa… Witryna14 kwi 2024 · Abstract. Ultrasound contrast agent (UCA) based molecular imaging is a rapidly growing field in biomedical research.
