Enhanced ct is generally applicable to patients who cannot be clearly diagnosed by ordinary ct or whose body has already experienced symptoms that are clearly not suitable for ordinary ct.
Enhanced ct is more expensive and requires injection of contrast agent, which may increase the burden on the patient’s body, and some patients may even be allergic to the contrast agent, which may easily cause harm.
Although the contrast agent injected during the examination of enhanced ct has relatively fewer side effects, it is not recommended for people with allergies because the contrast agent is prone to inducing allergies. At the same time, the contrast agent needs to be excreted through the kidneys, so patients with poor renal function are not recommended to do, so as not to aggravate the burden on the kidneys. Patients with hyperthyroidism and cardiac insufficiency should also avoid enhanced ct examination, as the contrast agent is easy to aggravate their own diseases after use.
It is recommended that patients choose the appropriate examination method under the guidance of the doctor. Enhanced ct examination must be done before the appropriate examination, to avoid accidents in the examination.
