Iohexol is a non-ionic, water-soluble iodinated contrast agent widely utilized in medical imaging, particularly in computed tomography (CT) scans and angiography. Its unique chemical structure, featuring multiple hydroxyl groups and iodine atoms, enhances its ability to provide clear and detailed images of internal organs and blood vessels, making it invaluable in diagnostic procedures. Iohexol's low osmolality and reduced viscosity compared to traditional contrast agents contribute to improved patient comfort and reduced risk of adverse reactions, which is crucial for patients with compromised renal function or allergies.

In addition to its primary use in radiology, Iohexol has applications in various research settings, including pharmacokinetics and drug delivery studies. Its ability to serve as a tracer in biological systems allows researchers to investigate the dynamics of drug absorption and distribution. Furthermore, Iohexol's compatibility with a range of imaging modalities enhances its versatility, making it a preferred choice for both clinical and research applications. With its proven efficacy and safety profile, Iohexol continues to be a cornerstone in the field of medical imaging.
