MRI of the brain during pregnancy: is it possible?


The main methods in vivo study of the brain today are CT and especially MRI. It is not surprising that in cases of suspected serious pathology of the brain, the doctors resorted to magnetic resonance imaging. MRI of the brain in pregnancy is prescribed for the same indications as for other categories of patients. The most common causes are:

  1. Signs of violation of brain blood circulation.
  2. Increased intracranial pressure.
  3. Neurological symptoms pointing to disease of the CNS.
  4. Violation of the functions of the senses.

Such a study allows us to consider the brain in layers, in all possible projections and to reconstruct a three-dimensional image, which is a large-scale field for the diagnosis of diseases of the brain. Miss pathology in this survey it is simply impossible!

In General, MRI is considered as safe method in the study (the second after the ultrasound examination), as in contrast to CT and x-ray does not give dose. Not established a single case, which tracks would be a direct correlation of adverse effects of the Mr-tomography. This is one of the few methods of research to date in which the performance of the diagnosis combined with safety for the patient.

Nevertheless, the only recognized a very safe method of examination during pregnancy is ultrasound, and the appointment of CT, MRI, x-ray require medical testimony. And if these readings are relative, the doctor will seek to postpone the survey of women in the postnatal period.

How to feed your baby if you had an MRI with contrast?

There is no single point of view about how harmful contrast to the fetus, although one should remember that any medical procedures involve risk. A contrasting substance is definitely an allergen for some people, so contrast-enhanced MRI during pregnancy, doctors try not to do it.

With regard to the postpartum period, when the child is breastfed, the manufacturers of contrasts warn to resume breastfeeding should be within 24 to 48 hours after injection of contrast into a vein of the mother. The fact that the contrast circulates through all the physiological fluids of man and is also found in breast milk that can cause allergies in children.

When pregnant it is impossible to conduct MRI research under any circumstances?

Absolute contraindications for the procedure pregnant women the same as other categories of patients:

  • The presence of a pacemaker, surgical staples and other medical devices within the body of ferromagnets.
  • Middle ear implants of ferromagnetic materials.
  • Renal pathology, which complicates the withdrawal of contrast from the body.
  • Excessively overweight.
  • Hemostatic clips to blood vessels of the brain.

Relative contraindications:

  • Insulin pump.
  • Paramagnetic middle ear implants.

  • The prosthetic heart valves.
  • The inner ear prosthesis with metal parts.

If the risk is warranted?

Any medical procedure has its individual implications for each person and therefore it is necessary to correlate risk of harm from its implementation and use from the received diagnostic data. MRI can be done during pregnancy, when there is a threat to the life or health of the mother. In any case, assigning you an MRI, the doctor has a clear reason. This study – the gold standard for the diagnosis of brain structures.
