Not in the public system, but i have heard of many Obs who "just check how bub is going" with a "quick" ultrasound every appointment! And then there are the places who offer 3D/4D scans for cash where you don't need a prescription. You can even bring friends and nibblies, hang out on the couch and watch bub wiggle!

Well that depends on your perspective really. If you have cancer, treatment is not necessary but is more than often helpful. Not a lot of things are not necessary, but doesn't mean they don't help.But I have plenty of friends who have no scans- they are not necessary.
If i had a baby with a life threatening illness that needed a team of pediatric surgeons on the ready at it's birth, the only way i could possible know would be to have an ultrasound.
I read the first link that referred to a study that showed that routine ultrasounds increase the incidence of left handedness?! i have heard that before as well as a myriad of other wild claims. The fact is that none of the claims are backed up by any credible study (well the left handed one is, but really?!).
If the only reason you are having the ultrasound is for the pics then i agree, you shouldn't be having it. But if you are having it to check the health of you baby and to look for any causes for concern then i think it is a very valuable tool.
ETA- you are correct in saying that there is no specific evidence saying ultrasound is 100% safe. Ultrasound hasn't really been around for that long, but chances are most of us had an ultrasound inutero. I guess if there was any cause for concern, or a study actually showed that ultrasound was in anyway unsafe then people would devote time and effort into proving it was safe.

We had lots with DS, this time we're trying to limit it. I think ultrasound is a very important diagnostic tool when used judiciously during pregnancy.
In my opinion, the 20-week ultrasound is a good idea for all pregnancies, but that's probably the only one that is really needed, barring other medical indications.
But there are lots of reasons people have routine ultrasounds - it can be very reassuring, especially in cases where parents are particularly anxious and not yet feeling regular movements. I don't think the evidence is conclusive either way, so it's probably not fair to judge parents that decide to get lots of scans, particularly when many private-practice OBs will offer them as routine (which obviously suggests they see no risk in having many scans).
We've had 3 this pregnancy. 1 early on due to bleeding. Then we had our official 7-week one to confirm viability (standard after IVF). Then the 20-week one. We won't have more unless complications arise.
I would be more concerned about your OB bullying you than whether your not the 20-week ultrasound is worthwhile doing. All the best

I only had the 20week ultrasound. I knew my dates so i didn't need a dating scan, i am low risk for downs syndrome and we are against termination (even if bub had something wrong with it) and so had no need for the 12 week one. I really wanted to see bub more often but there was no need for it.
agreed. if it's low risk pregnancy then obstetricians don't really need to see what position bub is in cuz it can change every day....so on the day of labour it will be different from every other day...why do they need to 'check' on it??I would be more concerned about your OB bullying you than whether your not the 20-week ultrasound is worthwhile doing.

i have had 2 scans already one for dates and one for check up as i had bleeding and i have had previous m/c's. my ob checks with u/s each visit to make sure bubs is growing and no problems have arised. scans are useful i had a placenta covering some of my old c section scar at 20 weeks and having a repeat c section it can be dangerous, so i was monitored by my ob to make sure it moved. its good to know certain things as they can be life threatening and will be doing the same things with this pregnancy to ensure my baby is healthy and stays safe until he or she is ready to meet us.

All of my scans are bulk billed - so a portion i get back form medicare. I am not through a hospital.
I can certainly tell you though if you have had an ectopic (or more than one) then the dating/viability scan IS absolutely necessary - for both medical reasons and for emotional reasons.
As for the 12/3 week scan - if you are a parent who is concerned about DS, then this scan also matters - and has nothing to do with being "so far away from the birth" - you may not even want the birth to take place if you child has such abnormalities!
As a PP said, there are many couples who use IVF and the early scan is also vital to ensuring a viable pregnancy in this situation.
(Oh and the 'should' I used was referring to the ones deemed 'necessary', nothing to do with what a patient should or shouldn't do - there is a should about it, the ones your doctor says you 'should' have.)
I have never been offered more scans during pregnancy, but them my viable pregnancies have always been completely normal with no issues, and my pregnancy with conjoined twins did not last long enough to need anymore.
I have also never been through an OB, so not been offered them in a routine examination - and I certainly wouldn't take them if I had, they aren't necessary (for me).
It is a personal decision, but I really don't think there should be any illusions about the fact that there are viable reasons behind each of the 3 scans that are routinely given in this country, and they are very serious reasons and often vital for the informed decision making of both parents and care providers.
As for the husband wanting pictures - I really don't think that is such a bad reason when you think about it. We get to feel the baby, experience it in full. They get a kick every so often and see a growing belly - they have no other connection or attachment to the baby and I can totally understand a partner wanting the pictures - it is a more tangible thing to get attached to - and from what I understand, that is a fairly normal male way of thinking. I know my husband felt much better and more connected after seeing the ultrasounds (and if he couldn't be there for the scan in person, the pictures are vital.) Just something to think about before we judge how silly or foolish a reason it is for having an ultrasound.

Being High Risk I have had a lot of scans, TBH I have lost count, of how many internal and external scans I have had, starting from 7 + 4 weeks I started to lose one of the twins and bled for weeks and on numerous occassions it looked as though the second twin wasn't going to make it as well. I had a very short cervix, so have been under constant monitoring for that to ensure that it is not funneling or shortening again, retained product from the first twin, my placenta is located over the septum (septate uterus) so where there is basically no blood flow in that section, my placenta is small so we are on constant monitoring for growth restriction, via growth scans and uterine dopplers. Low amniotic fluids which have picked up of late, and having constant BH's and being on Meds to calm them and having had a prem before, without all the monitoring and scans I hesitate to think about where we would be as I have been on rest, no lifting for the last few months.
So while it isn't ideal and not my preferred way, we need to be aware with what we are dealing with, and are making all attempts to make this pregnancy as long as possible, and a lot of the information we are looking at you can only get from US.
My OB take a number of images of my scans and puts them on file and refers back to them at each appointment, they are a good reference for her as a visual image to compare things rather than just a measurement, but a lot of the photos are of my cervix, the placenta, and not just a series of photos of a growing baby.....
So while it is not ideal to have so many scans we have to weigh up the risks and delivering a baby very prematurely or using technology to prolong a pregnancy for as long as possible I know what my choice is.
I hesitate to agree with articles due to the lack of referencing in the articles, and the age there is much mroe recent information, I have read a bit about the risks of having too many US but there is certainly a point when the benefits outweigh the risks.

Totally agree with this statement!! Very good point!

My key concern with ultrasound is their inherent ability to undermine a mother's own trust in her body, by placing the knowledge of her baby in the hands of a care provider.
Placenta, baby and cervix conditions can all change, and I question why doctors need to "know" what is going on at a regular basis (as in every appointment for a "quick look"). I support a 20 week morphology scan, to check for congenital issues which may need treatment at the time of birth, but even then, I wonder how many conditions need "in-utero" diagnosis and immediate treatment (just a hesitation, but I still support morphology scans).
In the case of bleeding, high risk pregnancies, or concerns about DS or other conditions, then I can see further ultrasounds are useful...but as was discussed in other threads...sometimes ultrasounds just stress out parents, rather than put their minds at ease.
As for checking size of the baby I think its a waste of time. It seems there is a great fear that babies will somehow be too big for women to birth. How can we grow babies that are too big for our bodies??? I just don't understand that...unless of course the woman has GD, but that can be detected by other means.
Ultrasounds haven't been checked for safety, we just assume they're safe because there are no obvious side effects. That in itself is a concern for our whole society, because we seem to embrace technology so openly, often with little critique of the knowledge the so called experts have on the subject. And lets face it...who wants to subject their baby to randomised trials on the safety of prenatal tests? That's why it hasn't been tested. We are the guinea pigs.
Registered User
There are always people such as yourself who do not rush to embrace technology without seeing evidence of its safety and are willing to speak up about it. When enough people are speaking up, that's when they go to the trouble of proving their claims.
Personally, I'm grateful for the scans we've had. We took so long and went through so much to get pg and had one early loss along the way, so I find it reassuring to know that everything is on track. I can't wait until I can actually feel movement so that I can feel reassured without any tests.
I think, given the prevalence of pg u/s these days, if it were going to cause a problem, they would have seen a pattern of problems by now. This is not the first generation of children to be spied on in-utero. But that is not the same as proving that it's safe, so your point is entirely valid.

So true. One of my friends had a baby with a huge cyst in her chest that affected the size of her babies' lungs and thus her ability to breath. Her baby was born with a resuscitation team on standby and an operating theatre ready. End result - a healthy child who otherwise may not have survived her first hours.

As with all things not fully understood or explainable u/s should be used with caution. Do I think they are over used...yeah, I didn't need a "dating scan" I knew when all of my babies were due, but I was asked to get them, for my Dr, for my records etc. Most wm then have the 19/20 wk to check the sex or just to check on bub. A few it seems is the norm but some wm do have on eevery Ob visit and many are told they have to have to have size chacks for the last 4 wks etc. I feel that unless there is concern or medical reasons then u/s should be used sparingly, yes a lot of ppl can say the u/s picked up something that needed immediate neonatal treatment but if it was found in 5 yrs that u/s caused some weird anomaly and no Ob wanted to perform one we'd all be left scratching our heads...One of those damned if you do, damned if you don't things perhaps???

Really? Pretty sure all the mum's i know have had it to check the health of their baby and to look for any signs of a problem.
Registered User
ITA I certainly wasn't focused on the sex, I was more concerned that everything was in the right spot, that the placenta was doing what it needed to and my cervix length was doing ok...
Moderator
Yeah, if you have a comlete placenta praevia it's nice to know beforehand rather than when you are bleeding out in labour.

Considering I didn't want to find out the sex of this bub that was not the reason why I had the 20 week ultrasound. I had it to make sure bub was healthy and everything was where it is meant to be especially considering I am giving birth at a fairly remote hospital and would have liked to know early if I was going to have to transfer to a capital city, and yes my placenta was slightly low lying so needed to be checked later. The number of things i have seen picked up on this ultrasound that have saved both mum's and bub's lives is amazing.
