After having an angiogram, you usually have 3-6 months before you are ready to have a baby. The effects of having an imaging on having a baby come mainly from the effects of the radiation. The effects of the contrast medium itself on the body are negligible. This is because the contrast media, especially those commonly used nowadays, are not absorbed by the body and can be excreted by the kidneys or the intestines very quickly (usually within one day). The main effect comes from the radiation, after the radiological examination, especially the radiological examination with high dose such as CT, the requirement of more than 3 months is not too bad. Clinically, it is now stipulated that 3-6 months is enough time to prepare for having a baby, but of course, you can prepare a little bit in advance, such as taking folic acid tablets, regular work and rest, balanced nutrition, and do some of these preparations in advance is possible. The real preparation for a child should be placed after 3 months, the time is not too far. If you are really unsure, 6 months is also enough, so it is generally considered that 3-6 months is enough time.
