Diatrizoate Sodium is primarily used as a contrast medium in diagnostic radiology to improve visualization of internal structures. It is administered intravenously or orally for procedures such as angiography, urography, and gastrointestinal imaging. The compound’s high iodine content ensures optimal X-ray absorption, enabling clear differentiation between tissues and fluids. Its rapid excretion via the kidneys minimizes systemic exposure, making it a safe choice for patients with normal renal function. Always follow clinical guidelines for dosage and administration to prevent adverse reactions.
