CT scans are required for patients with tumors, cerebral hemorrhages, and cerebral infarctions in the brain, and CT scans can also be used to confirm the diagnosis of lumps in the lungs, chest, gallbladder, pelvis, and heart chambers.
However, many people know that the process of CT examination will cause some radiation damage to the body, so what are the risks of doing CT examination?
What are the risks associated with a CT scan?
In the process of CT examination, people are often exposed to ionizing radiation, and the amount of radiation will be much higher than that of X-ray, the main reason is that compared with X-ray, CT examination is more in-depth and detailed, and the dose is relatively high, and low-dose CT scan will not cause long-term harm to physical health.
However, high doses of CT can increase the risk of cancer, especially for expectant mothers who are pregnant, and it is important to inform the doctor before having a CT scan.
Because CT examination will cause certain damage to the baby in the body, and will also increase the probability of inducing fetal malformations, in general, for pregnant women, doctors will recommend ultrasound and MRI examinations to avoid harming the fetus.
People who are weak or have a sensitive constitution are very likely to have allergic reactions due to the developer, and the symptoms are mild as itching and rashes on the surface of the skin, and serious will also harm the body.
What groups of people are not suitable for CT scanning?
1. Young children
For some young children, because their own immune system is not fully established, it will be more sensitive to the radiation of CT examination, and their body is in a stage of growth and development, their own cell division speed is relatively fast, so it is easy to damage DNA, if regular CT examination is very likely to cause cell division, and then induce cancer.
2. People with renal insufficiency and heart disease
People with renal insufficiency should also try not to do CT examination, mainly because intravenous hypertension injection of iodine is often required before CT examination, and the excretory function of the kidneys of people with renal insufficiency is abnormal and cannot be excreted normally, so it will poison the kidneys and cause kidney failure.
In addition, for people with arrhythmia and congestive heart disease, CT scans cannot be done to avoid accidents.
3. People with allergies
If you are prone to allergies, you will also have an allergic reaction to iodine contrast media, so you cannot do a CT scan.
Because in the process of CT examination, there will be ionization, which will affect the macromolecular structure in the body, affect the normal decomposition of enzymes, and then cause certain damage to normal cells, so that the body will be allergic.
In addition, for people with diabetes and severe dehydration, it is necessary to be cautious during the CT examination, so be sure to tell the doctor about your condition in advance.
All in all, an occasional CT scan in life will not cause great harm to the body, but it should not be too frequent, and after the examination, you should clean up your clothes and body in time, and drink a lot of water immediately, and eliminate the toxins in the body by urination or defecation as soon as possible.
