NCIt definition : An organic, iodinated radiopaque X-ray contrast medium used in diagnostic radiography.
The iodine moiety of diatrizoate is not penetrable by X-rays, therefore it blocks
the X-ray film exposure by radiation. This makes it possible to distinguish, on X-ray
film, body parts that contain diatrizoate meglumine from body parts that do not contain
this agent and allows for visualization of different body structures.;
