Keepsake vs Medical Ultrasound in Ajax: Know the Difference
Keepsake 3D/4D or medical pregnancy scan? Ajax parents can learn how the two differ in purpose, booking and reporting, and why one never replaces the other.

Two pregnant people can lie on what looks like the same kind of exam bed, in the same kind of dimly lit room, while a probe glides over the same kind of gel, and still be having completely different appointments. One is there because a midwife or doctor wants information about the pregnancy. The other is there because she wants to see her baby’s face and share that moment with her mother and her partner. From the outside the visits look alike. Underneath, almost everything is different: the reason for the scan, who arranges it, what the person holding the probe is focused on, what happens to the images afterwards and what you can reasonably expect to learn.
For expecting families in Ajax, Pickering and Whitby, understanding that difference is useful for a simple reason. It helps you get the right scan at the right time and keeps a lovely optional experience from being mistaken for something it is not. This article sets the two side by side. It does not repeat our advice on the best weeks for a 3D/4D session or our list of questions to ask before booking one; those posts cover the planning. Here the focus is on what separates a keepsake session from a medical one, and why that line matters.
Same technology, two different jobs
Both kinds of appointment use ultrasound: high-frequency sound waves sent into the body, with the returning echoes turned into a picture. There is no X-ray radiation involved in either. The basic physics is shared, and so is a good deal of the equipment.
What changes is the job the scan is being asked to do.
- A medical (diagnostic) obstetrical ultrasound is a test. It is ordered to answer clinical questions about the pregnancy, such as how far along it is, how the baby is growing, or where the placenta sits.
- A keepsake 3D/4D ultrasound is an experience. Its purpose is to let you see your baby in a more lifelike, three-dimensional way, often in motion, and to take some of those images home.
A useful way to think about it is the difference between a home inspection and a family photo taken on the front porch. Both involve someone looking closely at the same house. Only one is designed to tell you whether the foundation is sound.
Who starts the process
Medical scans begin with your provider
A diagnostic pregnancy ultrasound usually begins with a requisition from your physician, midwife or nurse practitioner. That form tells the imaging clinic what kind of scan is needed and, often, why. The timing is guided by your care plan rather than by personal preference, although you can usually choose a convenient day and time within the window your provider suggests. At Rossland Diagnostic Clinic, these scans are booked through our general and obstetrical ultrasound service, and patients are asked to bring their health card.
Keepsake sessions begin with you
A 3D/4D keepsake session is something families choose for themselves. You decide whether you want one at all, when it fits into your pregnancy, and who you would like in the room. Family and friends are welcome at these sessions, which is part of what makes them feel like an occasion rather than a test. Because packages vary, the simplest approach is to call the clinic and ask what is currently offered.
What the person scanning is paying attention to
This is perhaps the least visible difference, and the most important.
During a diagnostic scan, the sonographer follows a structured approach. Depending on the type of exam, that can mean taking specific measurements, documenting particular views, and recording what is needed for a physician to interpret afterwards. Much of what they capture would mean little to a parent watching the screen, and they may not talk you through it in detail. That quietness is not a sign that something is wrong. It reflects the fact that interpretation and reporting happen as part of a separate process.
During a keepsake session, the attention shifts towards the view itself. The goal is to find angles where the baby’s face, hands or feet show up clearly, to wait for a yawn or a stretch, and to capture images that feel personal. The pace is often slower and more conversational, and the screen is usually positioned so everyone can see.
Put simply:
- In a medical scan, the images serve a report.
- In a keepsake scan, the images are the point.
Reports, results and where the images go
A diagnostic ultrasound produces information that becomes part of your medical care. The images are interpreted and a report is prepared for the health-care provider who ordered the exam. If you have wondered how that hand-off works, our article on how imaging results reach your doctor explains the general path.
A keepsake session does not work that way. It is not a substitute for a diagnostic assessment and should not be treated as one. You leave with keepsake images to enjoy and share, not with a medical opinion about the pregnancy. If a family hopes to use a keepsake visit to “double-check” something that is worrying them, the honest answer is that it is the wrong tool. Concerns about the pregnancy belong with your health-care provider, who can decide whether a diagnostic scan or another kind of assessment is needed.
A side-by-side summary
| Medical obstetrical ultrasound | Keepsake 3D/4D ultrasound | |
|---|---|---|
| Main purpose | Answer clinical questions about the pregnancy | Let the family see and remember the baby |
| How it is arranged | Requisition from your provider | You book it yourself |
| Timing | Guided by your care plan | Chosen for the best views and your schedule |
| Who is in the room | Usually you, sometimes a support person (call to confirm) | Family and friends welcome |
| What follows | A report for your provider | Keepsake images for you |
| Replaces the other? | No | No |
That last row deserves its own section.
Why one never replaces the other
It can be tempting to think that a longer, more detailed-looking 3D/4D session might make a separate medical scan unnecessary. It does not. The keepsake images may look striking, but they are not gathered or reviewed in the way a diagnostic examination is. They are also not designed to look at the things a medical scan focuses on.
The reverse is also true. Your diagnostic scans are not designed as keepsake sessions. Many people are surprised by how little of the baby’s face they see during a medical scan, or by how few pictures, if any, they take home. That is not a shortcoming of the scan. It simply has a different job.
The practical rule we encourage every family to follow:
- Keep every scan your provider recommends. Do not move, skip or delay a diagnostic appointment because a keepsake session is planned.
- Treat the keepsake as an addition. It sits alongside your care, not inside it.
- Raise questions with your provider. If you are unsure whether a keepsake session suits your pregnancy, your doctor or midwife is the right person to ask.
Some health organizations encourage caution about ultrasound done purely for non-medical reasons, which is one more reason to talk it through with the person caring for your pregnancy before you book.
Finding out the baby’s sex: which scan, and when
Families often ask whether they will learn the sex at a medical scan or a keepsake one. The answer depends on the setting and on your wishes.
At a diagnostic scan, the sonographer’s priority is the clinical exam. Whether the sex is shared, and how, can depend on clinic practice and on what you ask for, so it is worth raising it before the scan begins and calling ahead if it matters to you.
At a keepsake session, learning the sex is often part of the appeal. At our clinic, sex determination at a 3D/4D session is possible from as early as 23 weeks, though a baby’s position can always make things harder to see. If you are planning a reveal, our post on planning a gender reveal with a 3D/4D ultrasound has ideas for making it work.
Common mix-ups we hear about
A few misunderstandings come up regularly. None of them are silly, and all of them make sense given how similar the two appointments can look.
“My keepsake scan looked fine, so I can skip my anatomy scan”
Please do not. A keepsake session is not an assessment, and seeing a happy, wriggling baby on the screen is not the same as the structured look your provider has requested.
“The sonographer barely spoke during my medical scan, so something must be wrong”
Quiet concentration is normal during diagnostic exams. Your provider will receive the report and discuss it with you.
“I want both on the same day to save a trip”
Families sometimes ask about combining visits. Whether that is possible depends on scheduling and on your requisition, so call the clinic to confirm what can be arranged. Many people find it more enjoyable to keep the keepsake session on its own day anyway, so it feels like a celebration rather than an add-on to a medical appointment.
“I need a requisition for a 3D/4D session”
A keepsake session is elective, so it is booked by you. If you have any doubt about what to bring, ask when you call.
When to skip both and seek help now
Neither a keepsake session nor a routine diagnostic booking is the right response to an urgent problem in pregnancy. If you have heavy vaginal bleeding, severe abdominal pain, a gush of fluid, fainting, chest pain or trouble breathing, call 911 or go to the nearest emergency department. For changes that worry you but are not an emergency, such as noticing that your baby is moving less than usual, contact your health-care provider or labour and delivery unit promptly rather than waiting for a scheduled appointment. A community imaging clinic is not set up for emergency care.
Choosing what is right for your family
There is no single correct way to approach pregnancy imaging beyond one firm rule: the medical scans your provider recommends come first. After that, a keepsake session is entirely optional. Some families love the idea and plan it months in advance. Others are content with the images from their diagnostic scans and feel no need for more. Both are perfectly reasonable choices, and we see plenty of each among the Ajax families who visit us.
If you do decide to book, it helps to go in with clear expectations. You are there to meet your baby in a new way, not to receive medical news. Babies set their own schedules, so a hand in front of the face or a stubborn turn towards the back is part of the experience. Clinics often have practical tips for encouraging movement; ask when you book.
