![]() In turn, those bouncing sound waves create a visual image. The transducer emits sound waves, which bounce around and off of your internal organs and the baby. Then, he will roll a device called a transducer over your belly. When you go in for a pregnancy-related ultrasound, the tech will put gel on your stomach. The only difference is the visual outcome.Īll three ultrasound types are noninvasive and use high-frequency sound waves to create pictures – sonograms – of what’s going on inside your body (Source: Cleveland Clinic). No matter which ultrasound you choose, the technician will conduct them all in primarily the same way. This Youtube video shows exactly what each ultrasound looks like and makes it easy to distinguish between them:ĭespite their visual differences, all three ultrasounds are performed similarly. Additionally, 4D ultrasounds share the same video-like movement as 2D ultrasounds. The image quality is fantastic and exactly like what you’d see in a 3D ultrasound. That’s why I say it’s a hybrid of 2D and 3D. (Imagine the “burst photos” feature on your cell phone it’s similar to that.) As a result, a 4D ultrasound looks more like a video than a photograph.Įven so, it retains the high-quality, three-dimensional imaging quality of 3D ultrasounds. On the other hand, during a 4D ultrasound, multiple pictures are taken in rapid succession. The sonographer can rotate it, but the image itself stays immobile. However, the picture is more like a photograph than a video. Features like noses, eyes, fingers, toes, and tongues are clearly visible in a 3D ultrasound. They give prospective parents a more accurate look at what their babies look like. Unlike 2D ultrasounds, 3D ultrasounds are three-dimensional. What’s the Difference Between a 3D and 4D Ultrasound? Keep that in mind as we move into 3D and 4D ultrasounds. That’s the key takeaway – that they’re moving images. They produce flat, black and white moving images. ![]() It’s one of those flat, white-against-black moving pictures of fetuses that we see in almost every movie about pregnancy ever made. When most people think of ultrasound photos, it’s the 2D version that usually comes to mind.Įven though the technology for 3D ultrasounds has been around since the 1980s, 2D ultrasounds are probably the most well-known and widely used ultrasounds even today (Source: National Library of Medicine) 2D UltrasoundsĪ 2D ultrasound is the “old-school” ultrasound most people are used to seeing. Now, what exactly do I mean by that? Let’s break it down. Put simply, a 4D ultrasound is a high-quality ultrasound that’s somewhat of a hybrid between the 2D and 3D varieties. There are three main types of ultrasounds. What Is a 4D Ultrasound?Īlso known as sonography, ultrasounds are an essential component in most medical fields, especially obstetrics. ![]() I’ll also highlight the pros and cons of 4D ultrasounds and answer some other frequently asked questions about them. In this article, I’ll provide you with all the information you need to make an informed decision about whether or not to get a 4D ultrasound. However, the image is constantly updated, making it appear as though you’re watching a video instead of looking at a still, three-dimensional image. Visually, it looks exactly like a 3D ultrasound. However, with all the different ultrasound technologies available, it’s hard to decide which type you should get.Ī 4D ultrasound is one of the latest and most advanced ultrasound technologies. It’s the first time they get to see their baby. ![]() One of the most exciting doctor’s visits for prospective new parents is the ultrasound appointment.
