MRI of a fetus with Pentalogy of Cantrell. Magnetic resonance imaging (MRI), without MRI contrast agents, is not associated with any risk for the mother or the fetus, and together with medical ultrasonography, it is the technique of choice for medical imaging in pregnancy. [1]
The concerns in pregnancy are the same as for MRI in general, but the fetus may be more sensitive to the effects—particularly to heating and to noise. The use of gadolinium-based contrast media in pregnancy is an off-label indication and may be administered only in the lowest dose required to provide essential diagnostic information. [51]
Analysis of the mother-fetus neurocognitive model [4] provided insights into the conditions of natural neuromodulation of the fetal nervous system during pregnancy. [3] Based on these results, the article suggested the hypothesis of the origin of neurostimulation during gestation.
A first-of-its-kind case study has highlighted the ways in which the brain changes throughout pregnancy, ... image a woman’s brain while pregnant with an MRI without causing any harm to the ...
It is notable that the presence of thalamic stimulators significantly changes ECG patterns, and prevents the use of MRI. It is sometimes regarded as a better alternative to pallidotomy or thalamotomy because it is non-permanent. For optimal installation, the patient is awake during the procedure, and talks to the surgeon to find the best placement.
Neurostimulation technology can improve the life quality of those who are severely paralyzed or have profound losses to various sense organs, as well as for permanent reduction of severe, chronic pain which would otherwise require constant (around-the-clock), high-dose opioid therapy (such as neuropathic pain and spinal-cord injury).

TMS can be used clinically to measure activity and function of specific brain circuits in humans, most commonly with single or paired magnetic pulses. [9] The most widely accepted use is in measuring the connection between the primary motor cortex of the central nervous system and the peripheral nervous system to evaluate damage related to past or progressive neurologic insult.
