What do the numbers and codes on a baby scan actually mean?

I used to just smile and nod, but now I get curious. At my scan near The Arboretum, the sonographer broke it down: CRL is crown–rump length, GA is gestational age, and EDD means estimated due date. Ask politely and most Nottingham clinics will explain as they go. It’s a brilliant window into how your baby is measured.

Is it true you can hear a baby’s heartbeat as early as 6 weeks?

Yes—but it depends. Clinics near West Bridgford often use a transvaginal ultrasound at that stage, and with luck, you’ll hear that fast flicker. If not, don’t panic—it’s still early. By 8 or 9 weeks, especially at a private scan, it’s more reliable. Some clinics even offer a heartbeat recording included in the package—I found one via Groupon that gave me mine on a little plush bear.

Why do some babies need a second hip scan after birth?

It’s not unusual. Some NHS scans (or private checks at places like Mapperley) flag that the hip joint looks underdeveloped or the baby’s position made things unclear. A follow-up is just to confirm normal movement. It’s a safety check, not a diagnosis—best to go in informed rather than worried.

Are x-rays ever used in baby scanning or is it all ultrasound these days?

Ultrasound all the way. X-rays involve radiation and aren’t used for unborn babies—simple as that. Clinics around Nottingham City Hospital and Beeston are very clear on this. The tech is soundwave-based and non-invasive, which makes it perfect for repeated scans throughout pregnancy.

How developed is a baby by the 12-week scan?

It’s wild what’s visible at that stage. Fingers, toes, nose, spine—all there. At my scan near the Lace Market, the sonographer pointed out even the flickering diaphragm. You might not feel anything yet, but a lot is already going on inside. That’s why people love those first scan photos—it’s the first proper glimpse.

How accurate is a scan for predicting baby weight later on?

Pretty good—but not exact science. Clinics in Wollaton say the margin can be up to 10%, depending on the baby's position and movement. They use femur length, head size, and abdominal circumference to estimate. Mine was off by 300g, which didn’t change any birth plans, but it’s worth knowing it’s just a forecast.

Can I still get baby scan photos printed or emailed after the appointment?

Most places offer both. The clinic I visited near Sherwood handed me two printed shots and emailed a digital copy within the hour. Some bundles (like a Groupon I saw last week) include extras like photo frames or USB drives—handy if you want to share with family who aren’t local.

What’s the difference between a 4D baby scan and a regular ultrasound?

Think of it this way: a 2D scan is like a line drawing, 3D adds the shape, and 4D adds motion. So during a 4D scan—like the ones in Hyson Green or Carlton—you might catch a little arm stretch or a nose rub. It's surreal and wonderful. Many clinics let you take a video home too.

Why do private clinics sometimes repeat a scan if the baby isn’t in position?

Because they want to get it right. If baby’s curled up or facing away, clinics often reschedule—especially if you’re doing a gender scan or 4D session. Mine near Trent Bridge offered a free second slot three days later, no fuss. Worth asking upfront—some even list that clearly in their Groupon deal terms.

Is there any real benefit to getting multiple private scans on top of NHS ones?

Depends on what you’re after. NHS covers the essentials at 12 and 20 weeks, but private scans give you extra reassurance, more images, and often a calmer, slower experience. Clinics in areas like Clifton or The Park often include wellbeing checks too. It’s peace of mind—especially if it fits your schedule or stress levels better.
