The Impact of the Angular Range - Case 2

A woman came to our breast Center for screening mammography, and she has scattered fibroglandular tissue. She had a prior left breast surgical biopsy. The mammogram detected is 7 millimeter mass sensor in the left breast. We initially worked it up with narrow angle tomography and then she was enrolled in our project and we subsequently performed wide angle Tomography Day two later. The image on the left is the narrow angle to Gramma Gram performed. You can see a scar marker which is showing where she had her prior surgical biopsy. As they scroll up and down through the narrow angle tomography. You can see there is a vague asymmetric density essentially in the breast. It is perceptible, but it doesn't look very different from other areas of Fabricland wrote issue another way of saying that is that it's continuity is fairly low. It's hard to detect without very careful observation. The margins of this density, which are the most important feature that we use for characterize any symmetry or very difficult to assess, barely visible the margins of this asymmetry, barely perceivable. If you now look at the wide angle tomographic image again, you can see a scar marker in the breast, and now you can see when I select print slice that this asymmetry is much more clearly seen with very clear margins. You can appreciate that this lesion is actually a little bit looking like a football. It's got little points on either end, which is a somewhat worrisome sign. And size and margins are much easier to appreciate then on the narrow angle. I'm going to scan up and down now to show you in plain resolution as you get in and out of this density.
