You’re just being nice
If you didn’t know, the 4D imagery has changed the way we look at ultrasounds. The days of grainy black-and-white, 2D images are almost gone and being replaced by grainy, orange-and-yellow 4D pictures. The two-dimension upgrade has really given parents better insight into what their baby will look like upon delivery.
Of course, newer isn’t always better. 4D ultrasounds can look confusing to the untrained eye, i.e., 99.99% of the population who don’t deal with ultrasonic frequencies regularly. We feel that the guy who complimented this “lasagna” was just being nice. It does not look crisp in any way. To be fair, we wouldn’t know what we were looking at, either.
