angiographic contrast agent
Iodinated substance injected to visualize coronary vessels during catheterization procedures.
Full Definition
A radiographic contrast medium, typically iodine-based, used during cardiac catheterization to enhance visualization of coronary arteries and cardiac structures. These agents allow real-time imaging of vessel anatomy, stenosis severity, and procedural outcomes. Editors must be aware of nephrotoxicity concerns and different osmolality classifications (iso-osmolar, low-osmolar, high-osmolar) when reviewing procedural reports and safety protocols.
Usage
Usage note: Specify osmolality type when relevant to patient safety discussions.
