Ethiodized oil, also known as Lipiodol, is a water-insoluble, iodine-containing contrast agent used in medical imaging, particularly for lymphangiography and computed tomography. It is a mixture of poppy seed oil and ethyl esters of the fatty acids, with 39-45% iodine by weight. Ethiodized oil is administered intravenously or intra-arterially to visualize the lymphatic system and blood vessels, aiding in the diagnosis and treatment of various conditions such as lymphatic disorders, tumors, and vascular malformations. Due to its slow clearance from the body, it can also be used as a drug delivery system for targeted chemotherapy. However, it is important to note that ethiodized oil is not suitable for use in patients with iodine allergies or those who are pregnant or breastfeeding.
