How long after an MRI can I get pregnant?

During pregnancy, you can do an MRI or even a CT scan. Generally speaking, the personal radiation dose of X-rays or CT scans currently performed is far less than the range that everyone needs to worry about, so the impact on pregnancy is negligible. However, many people wonder whether they can do an MRI before pregnancy. Let’s see how long it takes to get pregnant after an MRI.

How long does it take to get pregnant after an MRI?

Magnetic resonance imaging uses the principle of electromagnetic fields and nuclear resonance to produce images. It uses radio frequency waves to excite molecules in the body with non-zero magnetic moments in the electromagnetic field, and has nothing to do with radiation.

At present, there is no claim in clinical medicine that MRI has side effects on the body. The book describes the effects of MRI on reproduction very clearly, and MRI is not recommended within 3 months of pregnancy, but it still does not clearly point out what effects it will have on the fetus.

At present, very few pregnant patients undergo MRI examinations, and doctors will also give corresponding reminders to patients. The MRI examination does not affect the pregnancy plan.

Magnetic resonance imaging is different from X-rays and CT. Electromagnetic induction has little effect on pregnant women, and you can get pregnant next month after the test. Different from treatment with radioactive substances, diagnostic radioactive tests such as CT have little effect on male sperm and can be performed after one month. If you are exposed to X-rays directly, it will still have some impact on your pregnancy preparation, but you can consider pregnancy preparation after half a year.

1. Although ultrasound and MRI are risk-free, they should still be used with caution. It is recommended that they be used only to explain clinical medical issues or when they are beneficial to the patient.

2. With a few exceptions, the amount of radioactivity produced by diagnostic X-rays, CT scans, and nuclear medicine imaging is far less than the amount that would harm the fetus. If it is necessary to combine them with ultrasound and MRI to assist in diagnosis, it is recommended that their use should not be rejected.

3. It is recommended to limit the use of MRI and only recommend its use when it can greatly help diagnose or improve the prognosis of pregnant women and fetuses.

4. After using gadolinium contrast agent, there is no need to stop breastfeeding.
