Are 3D Mammograms a Game-Changer in Breast Health?


Learn how Jefferson Radiology’s 3D Mammography compares to traditional 2D screenings and how this technology has revolutionized mammograms and early detection.

Regular breast cancer screenings are essential for early detection and effective treatment. With the help of Jefferson Radiology’s advanced 3D Mammography, our expert physicians can detect cancer in its earliest stages and when it’s most treatable while significantly reducing false positives.

At Jefferson Radiology, we’re proud to offer the most advanced 3D Mammography technology available, Genius™ 3D, at all of our locations, including Avon, Bloomfield, Enfield, Farmington, Glastonbury, Granby, Hartford, West Hartford, and Wethersfield. This advanced technology allows our radiologists to evaluate breast tissue layer by layer, making fine details more visible and significantly improving the potential for early detection. But what exactly sets 3D apart from the traditional 2D mammogram? Let’s find out.

The Evolution from 2D to 3D Mammography—A Technological Leap

The shift from 2D to 3D Mammography marks a significant advancement in technology. Traditional 2D mammograms capture four flat images of the breasts, which can sometimes overlap tissues, obscuring details. In contrast, 3D Mammography, or digital breast tomosynthesis, significantly enhances breast cancer detection by capturing about 200 images from different angles to create a detailed 3D view, increasing detection by up to 41% over traditional 2D mammograms. This method drastically enhances visibility, allowing radiologists to detect abnormalities with greater accuracy and reducing the need for additional testing.

Advantages and Limitations of 3D Mammography:

Advantages of 3D Mammography:
  • Enhanced image clarity facilitates the detection of small tumors
  • Multiple angles reduce the overlap of breast tissues, which can hide cancers
  • Improved detection rates of breast cancer, especially in dense breast tissue
  • Reduced need for callbacks and follow-up imaging
  • Limited availability in certain regions
  • Potentially higher costs, though coverage is expanding

Advantages and Limitations of 2D Mammography:

While 3D Mammography has been spotlighted for its advancements in breast cancer screening, 2D Mammography remains a fundamental and widely accessible option. Understanding the advantages and limitations of 2D Mammography is important to making informed decisions about your breast health.

Advantages of 2D Mammography:
  • Widespread availability at most imaging centers
  • Quick imaging process
Limitations of 2D Mammography:
  • Reduced clarity of dense breast tissue, potentially missing abnormalities
  • Higher chance of additional testing

How Early is Early Detection?

3D Mammography is key in “early detection” because it has the capability to identify breast cancers when they are very small, much smaller than what was previously detectable with traditional 2D Mammography. This level of detail is crucial for catching cancers before they grow and become more challenging to treat. Part of catching cancer early is being sure to get your mammogram every year.

Why early detection with 3D Mammography is pivotal:

  • Detects millimeter-sized tumors
  • Fewer aggressive treatments, such as chemotherapy, are needed
  • Quicker return to daily life due to less invasive treatments
  • Higher survival rates

Minimizing Stress with Fewer False Positives

At Jefferson Radiology, we understand the emotional and physical toll that false positives can have. We’re committed to providing the most accurate results using advanced 3D technology, which has made significant advancements in reducing false positives.

Fewer false positives mean:

  • More accurate results reducing anxiety
  • Fewer unnecessary tests, saving financial resources
  • Minimized risk of complications from unnecessary interventions like biopsies
  • Increased peace of mind with more accurate results

You Have Options for Your Mammogram

When it comes to breast health, knowing that you have choices can make a significant difference in your healthcare experience. Many patients aren’t aware that they have the freedom to choose where to have their mammograms performed. It’s important to know that you can select a facility with sub-specialized physicians who bring extensive insight and precision to women’s imaging to align with your expectations for care and comfort.

What sets Jefferson Radiology physicians apart:

Jefferson Radiology’s team of multidisciplinary breast imaging specialists and interventionalists have dedicated their professional lives to providing women’s health services. Our breast imaging radiologists undertake years of specialized training, including four years of medical school, one year of internship, four years of diagnostic radiology residency, plus an additional year of fellowship in Breast Imaging. Many of our radiologists attended some of the top academic institutions in the nation, including Harvard, Brown, and other Ivy League universities. This extensive education and training equip our breast imagers with specialized proficiency, ensuring your mammograms are interpreted by physicians expertly trained in this area. Sub-specialized radiologists, like breast imagers, significantly enhance patient care with their precise diagnoses and deep insights, identifying key details for optimal treatment plans.

What sets Jefferson Radiology’s Mammograms apart:

  • We are a Mammography Accredited Facility by the American College of Radiology, ensuring the highest imaging quality and safety standards.
  • We utilize state-of-the-art 3D Mammography, offering shorter, more comfortable appointments that provide more accurate results.
  • Our caring technologists support you throughout the process, providing a better experience.


At Jefferson Radiology, our sub-specialized radiologists go beyond expertise; they are devoted physicians who have dedicated their professional lives to breast imaging. Leveraging advanced training, state-of-the-art technology, and a collaborative approach, we’re establishing new standards in mammography, one patient at a time. Jefferson Radiology is recognized as a Mammography Accredited Facility by the American College of Radiology.
