Introduction
CT iodinated contrast media refer to the iodine-based contrast agents used during CT examinations. Under normal circumstances, CT iodinated contrast media do not cause a decrease in body temperature. If required, their use should be performed under the guidance of a physician. Iodinated contrast agents are primarily used to enhance image contrast during CT scans, helping physicians observe internal structures in the patient more clearly.

CT iodine contrast agents refer to the iodine-based contrast agents used during CT examinations. Under normal circumstances, CT iodine contrast agents do not cause a decrease in body temperature. If necessary, it is recommended to proceed under a doctor's guidance. Detailed explanation is as follows:

The chemical properties and physiological effects of CT iodine contrast agents do not include the function of lowering body temperature. Iodine contrast agents are primarily used to enhance image contrast during CT scans, helping physicians observe internal structures of the body more clearly. Once administered, the contrast agent is rapidly distributed throughout the body and excreted via the kidneys, without causing a drop in body temperature during this process.

However, iodine contrast agents may cause发热 (fever-like) symptoms. After injection, the contrast agent may cause blood vessel dilation, and with the increase in blood volume, may induce systemic warmth or a sensation of heat. This is considered a normal physiological response. In the absence of other abnormal symptoms, special treatment is generally not required. Following the completion of the examination, as the contrast agent is excreted from the body, this phenomenon typically resolves on its own.

After the examination, it is important to drink plenty of water to promote the elimination of the contrast agent and reduce potential kidney damage. Additionally, strenuous physical activity should be avoided to prevent additional strain on the body.
