iodinated contrast
Contrast agents containing iodine used in vascular imaging to enhance vessel visualization on CT and conventional angiography.
Full Definition
Iodinated contrast agents are radiographic contrast materials containing iodine atoms that provide enhanced visualization of vascular structures during imaging procedures. These agents work by increasing the attenuation of X-rays, creating contrast between blood vessels and surrounding tissues. Iodinated contrast is essential for CT angiography, conventional angiography, and other vascular imaging procedures. The agents can be ionic or non-ionic, with varying osmolality and viscosity properties that affect patient tolerance and image quality. Proper selection and administration of iodinated contrast is crucial for optimal imaging results while minimizing the risk of contrast-induced nephropathy and allergic reactions.
Usage
Usage note: Specify type (ionic vs. non-ionic) when clinically relevant.
