     · Therefore, iodinated water-soluble oral contrast media are recommended for initial use in any study in which a bowel perforation is known or suspected. If an initial study with an iodinated contrast agent fails to demonstrate a suspected perforation, barium sulfate (preferably high-density barium) can then be safely administered.

  • Original Article The water-soluble iodinated contrast

     · Iodinated contrast media (ICM) is widely used in diagnostic work-ups. Sudden exposure to high iodide loads may disrupt thyroid hormone regulation, resulting in hypothyroidism (Wolff-Chaikoff effect) or hyperthyroidism (Jod-Base- dow phenomenon) [1, 2]. Iodinated contrast media-related thyroid dysfunction has been a popular topic due to the increased use of con-trast-enhanced imaging techniques in the past two decades. There have been several studies demonstrating altered thyroid hormone status following administration of ICM, particularly for computed tomography or coronary angiography [3, 4]. The Contrast Media Safety Committee of the European Society of Urogenital Radio- logy released guidelines that included recom-mendations for monitoring and managing thy-roid dysfunction in patients receiving ICM.
