A 5-month-old baby can tolerate CT radiation when the condition requires it and can have the test done.
CT examination is carried out through radiation, which may have certain effects on the human body. The baby’s body is not yet fully developed and CT examination is not normally recommended. However, if your baby is suffering from a major illness that requires a CT examination, you can have a CT examination on the advice of your doctor if you determine that the benefits of having a CT examination far outweigh the harms of having a CT examination.
A CT scan is usually done when the baby is quiet. If the baby is difficult to calm down, it will not be possible to perform the test. So it is better to put the baby to sleep before going for it.
Whether a 5-month-old baby should have a CT examination depends on the actual situation. CT examination for children is not absolutely forbidden, and CT is still a very effective means of examination when needed.
