Is ultrasound radiation?! After 25 years in the biz, it would be news to me – and to every other physician, engineer, and manufacturing company in relation to the technology. Not to mention those who have conducted biohazard testing in the field since the early 1900s…

What Exactly is Ultrasound? (Since It Isn’t Radiation)

Ultrasound is just that. Ultra Sound, or sound waves that work at a frequency far beyond human hearing. Like a fish-finder one might use on a boat. Or sonar used by the military. Human hearing ranges from about 20Hz (Hertz) to 20,000Hz (or 20kHz). When it comes to creating an ultrasound image, we work in the MHz range or millions of Hertz. An OB probe ranges from about 2MHz – 13MHz.

Ultrasound is a department of Radiology within a hospital, but it does not emit radiation.

So, Who Thinks Ultrasound is Radiation?!

Apparently, someone who hasn’t done her homework. I was floored recently while doing research for my book when I came across an author of a very popular pregnancy book (who will remain nameless…for now) who actually wrote that ultrasound is radiation.

She also claims that the Doppler used by physicians to obtain heart tones emits more radiation than scanning equipment! Wrong again, Doppler is ultrasound.

How does this happen? After all, she supposedly had the help of “knowledgeable” medical resources to write the book. Are they the only healthcare providers on the planet who don’t know Ultrasound is not X-Ray? And if not, why not?

I have no idea if this author has recanted this falsehood. I tried to Google it with no confirmation. If she did, I give her credit. If not, she owes an explanation and apology to her faithful readers and social media followers. She is incorrectly influencing millions of parents-to-be with this misinformation, and it’s not okay. She is adding needless fuel to the fire, and moms worry about enough as it is.

Additionally, she then goes on to advise moms to only have an ultrasound if they really want one, but to not have more than they need. To me, this begs the question…is it radiation or is it okay?

I would like to think she did not intentionally mislead her readership. But as a published author, ignorance is no excuse.

What is Radiation?

It is a transfer of energy that also travels in waves. For example, radiation is found in light from the sun, microwaves, and X-Rays. But not sound waves. And, yes, exposure to radiation can cause cancer. One example is skin cancer from too much sun exposure.

Consider this. When you go to the dentist, what is the first thing asked of any woman? “Is it possible you might be pregnant?” If the answer is “Yes” or “I’m not sure,” they shield your belly to protect Baby from the minuscule dose of radiation from a one-second X-Ray of your teeth.

If an obstetrician’s job is to manage the health and care of Mother and Baby, and it is, why then would docs expose their patients directly to radiation? And what about sonographers? We all would be directly exposed numerous times a day, every week for the duration of our careers. None of us, patients nor sonographers times decades, have died from cancer due to ultrasound exposure.

Is Ultrasound Safe?

Biohazard testing over decades has shown cavitation, the development of bubbles, over many consecutive hours of scanning in one area. So far, there have been no known effects for the very short-term use as needed by your doctor for your diagnostic scans. Therefore, it’s been the feeling of the medical community that the benefits far outweigh any risk, and they justify the use of ultrasound only for diagnostic purposes. So, no, they are not an advocate of the private entertainment ultrasound scan in the strip mall near you. And neither am I, but this is another post altogether. It’s also the responsibility of the sonographer to use as low a power setting as needed to obtain an adequate image.

***

One of the reasons I started this blog five years ago is because patients were misinformed – by Dr. Google, family, or friends. I expect as much from a random non-medical blogger, and I was even more enraged to find misinformation being doled out on popular pregnancy sites. But this took the cake.

It’s one thing to express one’s opinion. But when you’re making tons of money by persuading expectant moms to adopt your line of thinking, you have the responsibility to get your info right. No one says anyone has to be a fan of ultrasound. And as a mom, you have the right to decline. Before you do so, speak with your provider. You need only to understand your choice. Any mom who ever delivered a baby with serious problems was happy to know about it in advance for planning and educational, emotional, and delivery purposes. This, in fact, is the purpose of obstetric ultrasound.

And if you’re all about moms and choices, and those choices are power? The power only comes from a parent who makes an informed choice, not one based on misinformation. It is my wish and goal to simply and accurately explain ultrasound for moms-to-be and stamp out the misconceptions. Understanding is also power:)

Here’s to a happy, healthy, and informed pregnancy!

I’ve received questions lately regarding where to find fetal sex or gender in an ultrasound report. Can you always find this information in a report?
The short answer? No, not always.
Actually, we mostly do not record fetal sex, and it’s mostly not important to your doc. Typically, fetal sex is not pertinent information to the examination. Though parents may desire it, physicians don’t need this determination to manage your care and that of your baby if both are healthy. The above is true for most general OB practitioners in the US. However, every physician practices a little differently, and one can certainly dictate if he or she wants this info on all patient reports (if possible to determine). The case may be different if you are seeing a high-risk OB doc, aka a perinatologist. Their reports consist of much greater detail and may possibly include a fetal sex/gender guess.

Example of a Blank Report

In the images of a sample report taken from a monitor, you’ll notice there is a whole host of blanks to fill, but fetal sex is not one of them. On the first page where you see Sex: Other, this refers to the patient. Patient demographics were not entered here, so the Sex option defaulted to Other. We always include your LMP or EDC/EDD – aka baby due date. The larger blue space would be filled with fetal measurements, estimates of gestational age, and fetal weight as they are obtained.

OB ultrasound report

OB ultrasound report
In the pages above, you’ll note the list of fetal organs and structures we attempt to document on a mid-pregnancy anatomy screen. We only fill out the section called BPP in the 3rd Trimester when your doc orders this particular examination. And the CVP is usually only filled out when performing a Fetal Echo or detailed heart examination.

Exception to the Rule

There always seems to be at least one exception to every rule. Because the responsibility of a sonographer is to search out structural malformations, we also have to report suspicions of abnormal external genitalia. In other circumstances, we may see particular abnormalities that we might group together, as in the case of certain syndromes. Sometimes, knowing fetal sex helps physicians either support or rule out a particular chromosomal or structural problem. Some of these are gender specific. In the pic below, we have a designated space on a Comments page to expound on our findings. We can add fetal sex here if we feel it is pertinent information to the findings.
OB ultrasound report
In some countries, fetal sex is neither reported nor discussed with parents due to the cultural preference of one sex over another. And some facilities are beginning to incorporate policies against providing parents with this news due to litigious reasons. Unfortunately, such is life in the good ol’ US. Facilities want to limit their liability for guessing incorrectly by simply not allowing their sonographers to guess at all.
So, if you don’t want to know your baby’s sex (or even if you do!), don’t expect your ultrasound report to disclose that information. Your sonographer creates the images and report. We only include what is needed and leave out what is not!
Best wishes for happy and healthy!
