Fetal MRIs: Here’s What You Need to Know

Magnetic Resonance Imaging, also referred to as an MRI, is not just a medical test used on adults and children for diagnostic purposes. The imaging equipment can also be used on babies still in the womb.

If you’re new to the concept of fetal MRIs, our article will delve into everything you need to know. We’ll answer all the common questions and concerns you might have.

Why Would a Fetus Need an MRI?

A fetal MRI isn’t a standard examination performed on most unborn babies. It’s only recommended if there have been unusual or concerning findings discovered during an expectant mother’s standard ultrasound. This scan, if necessary, is typically only recommended after the first trimester.

A Southern Utah MRI performed on a pregnant woman can give medical professionals a closer look at the development of a fetus. Unlike a traditional ultrasound, an MRI can better distinguish different organs from each other, give a clearer image of internal body parts like the brain or spine, and provide a more in-depth examination of the function and health of the placenta.

What Do Fetal MRIs Detect?

While fetal MRIs themselves don’t detect medical issues on their own, this imaging equipment can help medical professionals discover and diagnose medical issues.

An MRI scan can help a doctor spot a variety of conditions including, but not excluded to, brain malformations, neural tube defects, cerebral infections, lung masses, abdominal tumors, and problems with the formation of the umbilical cord.

Can’t the MRI Be Done Once the Baby is Born?

While some testing can wait, sometimes it’s critical for an MRI to be performed before the baby is born.

Detecting malformations and medical conditions early via a fetal MRI can ensure a fetus gets the help they need to develop in the womb. A fetal MRI can also ultimately end up saving their life if there’s an underlying condition that can be resolved or improved before birth.

Because fetal MRIs cost more and are more extensive than traditional MRIs, doctors will only recommend them if they’re medically necessary. If the scan can wait until after the baby is born, then they will wait.

Are Fetal MRIs Safe?

Yes, fetal MRIs are safe for both the developing baby and the mother. A common misconception is that MRIs emit radiation, but the truth is, they don’t. Instead, they use radio waves and magnetic fields to take images.

There have also been multiple studies that demonstrate the safety of fetal MRIs. A research article backs the latter claim, stating that studies haven’t shown any short-term problems in fetuses that get an MRI. However, there is a lack of longitudinal studies to prove the long-term safety of these scans.

Nonetheless, fetal MRIs have been used for over 30 years, making them a trusted option in the medical field.

What are the Alternatives to a Fetal MRI?

Apart from a regular ultrasound, the closest imaging tool used on fetuses would be a CT scan. However, because CT scans emit radiation, there is a slight risk involved. Nonetheless, medical professionals make sure to use as little radiation as possible when performing a fetal CT scan.

Due to the increased safety of fetal MRIs, they are usually the preferred option. However, CT scans are typically better at imaging the skeleton and developing bones while a fetal MRI is better at imaging soft tissues and the brain. Ultimately, it will be the decision of the doctor to decide which scan would be most appropriate.

How are Fetal MRIs Carried Out?

Because the fetus is still in the womb, the mother will have to be involved in the procedure.

To start, the mother will be asked to remove any metal objects, such as jewelry. She will also fill out a screening form prior to the scan.

The mother will lie down on her back or left side on a standard MRI table. An abominable coil will be fastened around her belly. This device will help capture images of the fetus.

The scan will typically last about 30 to 45 minutes. While newer MRI machines are faster at capturing images, how long the scan will take will depend on numerous factors, such as the position of the baby and why the scan is being performed from the start.

Can They Sedate the Mother During a Fetal MRI Scan?

Unlike traditional MRI scans, sedation is not recommended during a fetal MRI. There are potential risks involved for the fetus, including cardiovascular or respiratory issues. However, brief exposure to sedation is relatively safe for the developing fetus.

In cases of severe anxiety, the mother may receive a light sedation at the lowest effective dose. If sedation is used during the scan, the mother’s vitals and the fetus’s heart rate will be regularly monitored.

Does a Fetal MRI Scan Hurt?

No, a fetal MRI, like a regular MRI, does not hurt the mother or the fetus.

The mother may still find the scan uncomfortable. Lying down in the same position for a half hour or longer may cause soreness. The mother may also be uncomfortable when it comes to the MRI machine’s loud noises and/or feeling anxious being in an enclosed space.

Medical professionals try to make getting a fetal MRI the most comfortable experience possible. They may allow the mother to lie in a different position, use a support pillow or cushion for added comfort, wear earplugs, listen to calming music, and/or receive a light sedation to help them relax. In some cases, they may allow breaks if the mother needs them.

How Much Do Fetal MRIs Cost?

The cost of a fetal MRI can vary drastically. It will depend on where you live, the medical facility you’re going through, why the MRI is needed, how long the scan lasts, and if more than one scan is needed. Your choice of payment method and whether or not you have insurance can also affect the out-of-pocket cost.

To give you a rough estimate, a fetal MRI can range from $500 to $3,000, with the national average being around $1,100. These costs are before insurance is billed.

Conclusion

A lot of people know that MRIs can be performed on individuals of all ages. However, many people are unaware that they can be performed on fetuses. Learning more in depth about this procedure, why it’s done, and how it works can bring peace of mind if your fetus or someone you know’s fetus has to have this medical test done.
