Iotrolan
Introduction
Overview
Overview
Iotrolan (trade name Isovist) is a radiocontrast agent, a substance used to improve the visibility of body structures on images obtained by X-ray techniques. It is particularly used to image spaces surrounding the central nervous system, such as the ventricles, after injection into the cerebrospinal fluid.[1] It can also be used to image joint spaces and in endoscopic retrograde cholangiopancreatography (ERCP).
Chemically, the substance is a dimer of triiodinated isophthalic acid derivatives.
