In the vast majority of cases, enhanced CT does not cause much harm to the human body. The effect of enhanced CT on the human body mainly refers to the radioactivity of the radiation on the human body and the side effects of the contrast agent on the human body. The radiation to the human body is not particularly large, although compared to ordinary CT, the scanning sequence is more, and the radioactivity is probably several times that of ordinary CT, but it is also far below the national safety range, so patients do not have to worry too much. As for the side effects of contrast agents on the human body, they vary from person to person. The majority of patients do not have allergic reactions, but there are a small number of people who will have allergic reactions of varying degrees due to their allergic constitution or other reasons, and mild ones, such as facial flushing, rash, and accelerated breathing, will soon disappear. treatment.
