There are no significant side effects from routine CT scanning of the brain, but there may be some side effects from CT enhancement of the brain due to injection of contrast media, such as contrast nephropathy.
The radiation dose of a routine CT scan of the brain is very low and there are basically no significant side effects on the human body. If a CT brain enhancement is performed, it may worsen the symptoms of hyperthyroidism or cause allergic reactions due to the injection of contrast material. In addition, the contrast agent can aggravate the damage to the kidneys, and even normal people may have kidney function damage.
Brain CT technology is becoming more and more advanced, the scanning time for the human body is getting shorter and shorter, especially the high rows of CT, the radiation to the human body is lower, so a single flat brain CT scan will not have a significant effect on the human body. However, if CT examination is abused or frequent radiological examination is performed, it may cause certain radiation damage to the examined person, and it will cause economic waste to the patient.
The doctor should be informed in detail of his/her condition before performing brain CT, and women of childbearing age, pregnant women, and infants and children should avoid CT examination as much as possible.
