Is CT examination harmful to health?

Yes, a CT examination is harmful, but it is not big.

When doing the examination, the dose used for X-ray fluoroscopy and photography is very small, which will be within the safe range. The radiation dose brought by a chest X-ray film is equivalent to the amount absorbed by our human body when watching TV for one hour, and the dose of chest X-ray film is equivalent to 1.5 times that of the film, which means that the damage caused by a chest X-ray film is equivalent to smoking three cigarettes. Most CT rooms will have certain standard walls, doors and windows, which have a strong protective effect.

When a patient has a head injury, brain CT is the most important imaging diagnostic method, with fast examination speed and high sensitivity to fresh bleeding. Can show brain edema and increased intracranial pressure, whether there are important lesions such as secondary cerebral hernia, brain CT can also diagnose skull fracture.

At the same time, it can also display the number, location, density, size and outline of intracranial tumors, whether intracranial hemorrhage and calcification and the degree of diffusion. Brain CT can better distinguish the size, range and quantity of hematoma, and can check whether the adjacent brain tissue is compressed, whether there is chronic or acute intracranial hematoma, judge the absorption and reduction of intracranial injury, and show some sequelae such as brain atrophy, hydrocephalus and encephalomalacia.
