Enhanced CT is generally not significantly harmful to the kidneys, but for patients with renal insufficiency, the contrast agent may aggravate renal impairment.
Enhanced CT, also known as enhanced CT, is a kind of examination based on ordinary CT examination by injecting iodine-containing contrast agent into the body to improve the resolution of the examination area and clarify the specific conditions of the lesion, which has the advantage of high accuracy.
Generally speaking, the contrast agent is metabolized by the kidneys and quickly excreted from the body, with little side effects and no obvious harm to the kidneys.
Some patients have renal insufficiency or even renal failure, at this time, enhanced CT examination may increase the burden on the kidneys, the contrast agent can not be metabolized and excreted in a timely manner, which has a great side effect on the human body and may lead to the deterioration of the original condition in severe cases, therefore, such patients should be weighed against the advantages and disadvantages of enhanced CT examination.
In addition, some patients are allergic to iodine-containing contrast agents, and enhanced CT examination may lead to allergic reactions, and in severe cases, anaphylactic shock may occur, which may jeopardize the patient’s life, so such patients should not undergo enhanced CT examination.
If patients need to undergo enhanced CT examination, it is recommended to go to a regular hospital to have the examination results prescribed and evaluated by a professional doctor.
