Benefits of 3D Mammography: What Makes It Different?
Why 3D Mammography Stands Out for Early Cancer Detection
If you’re due for a breast cancer screening, you’ve likely heard of 3D mammography—a newer technology that’s gaining attention for its accuracy, especially in women with dense breast tissue. But what are the benefits of 3D mammography, and is it really worth choosing over traditional 2D?
At Wisteria Imaging, we offer advanced 3D mammography using the Senographe Pristina™, the only FDA-approved system that provides a 3D image at the same low radiation dose as a standard digital mammogram. In this post, we’ll break down how it works, why it matters, and what you can expect before and after your screening.
How 3D Mammography Works
Also known as digital breast tomosynthesis, 3D mammography uses X-rays taken from multiple angles to build a three-dimensional image of the breast. Unlike 2D imaging, which flattens all breast tissue into one image per view, 3D captures “slices” of the breast and stacks them digitally. This makes it easier for radiologists to see through overlapping tissue and spot subtle abnormalities.
The 3D approach gives better visibility into dense tissue, reduces the chance of missing small cancers, and provides clearer boundaries around potentially suspicious areas—helping avoid unnecessary callbacks.
What the Research Says
Clinical studies continue to show the impact of 3D mammography on early cancer detection. According to a large-scale study published in JAMA Oncology, 3D mammography detected 41% more invasive breast cancers compared to 2D alone. The same study also noted a 15% reduction in false positives, which means fewer patients are called back for additional imaging or biopsies that turn out to be non-cancerous.
Other data from the American College of Radiology highlights how 3D mammograms improve diagnostic accuracy, especially for women with dense breasts, a known risk factor for breast cancer and a challenge for standard mammography.
Addressing Radiation Concerns
One of the most common questions we hear is, “Does 3D mean more radiation?”
Thanks to the technology we use at Wisteria Imaging—the GE Senographe Pristina™—the answer is no. This system is the only FDA-approved 3D mammography device that delivers images at the same low dose as a traditional 2D mammogram. You get a clearer view, better detection potential, and the same level of radiation exposure you’d receive during a standard screening.
It’s a win-win for your safety and your peace of mind.
Making Patients Comfortable
We understand that mammograms can feel stressful, especially if it’s your first time or you’ve had uncomfortable experiences in the past. That’s why we’ve designed our process to be as easy and supportive as possible.
At Wisteria Imaging, we offer:
A calm, private screening room
Ergonomic paddles and patient-friendly design in the Pristina™ system to reduce discomfort
A scan time of just 15–20 minutes, with no prep or downtime
You’ll be guided through every step, and your results will be reviewed by board-certified radiologists specializing in breast health.
What Happens if Your Results Are Abnormal?
An abnormal result doesn’t automatically mean cancer—it simply means something looks different and deserves a closer look. If this happens, you may be called back for a diagnostic mammogram, breast ultrasound, or occasionally a biopsy. Our radiology team works with your referring provider to ensure any next steps are clear and scheduled quickly.
We know waiting can be the hardest part. That’s why we aim to deliver most results within 24 to 48 hours, so you can move forward with confidence.
