Going DBT-Only: What Mammographers Need to Prepare in 2026

The shift is happening faster than many expected. Across the United States, breast imaging centers are moving away from offering both 2D digital mammography and 3D tomosynthesis — and going fully DBT. For mammographers, this transition from hybrid to DBT-only practice means more than just pressing a different button. It reshapes workflows, changes exam times, influences credentialing requirements, and demands new technical competencies.

If you have been working in a facility that still offers traditional 2D as a standalone option, 2026 may be the year your department makes the switch. Understanding what that means for your day-to-day work, your credentials, and your career mobility will help you stay ahead of the curve.

Let’s walk through what mammographers need to know — and do — to prepare for a DBT-only environment.

Why Facilities Are Going DBT-Only

Digital breast tomosynthesis has been around for over a decade, but adoption accelerated sharply after major payers began covering it at the same reimbursement rate as 2D mammography. Now, with the evidence base solidifying around improved cancer detection rates and lower recall rates, more facilities are making DBT the standard of care rather than an optional add-on.

When a facility goes DBT-only, it typically stops acquiring standalone 2D images altogether. Instead, every screening and diagnostic mammogram is performed as a tomosynthesis exam, often with a synthesized 2D image generated from the 3D dataset. This streamlines workflows, reduces patient confusion about ‘which kind’ of mammogram they are getting, and simplifies protocol management.

For mammographers, it means every patient you position will be scanned using tomosynthesis. The skill set shifts from occasional DBT use to full-time mastery.

Credentialing and Certification Expectations

One of the first questions mammographers ask is whether they need additional credentials to work in a DBT-only practice. The short answer: it depends on your state, your facility, and your current certifications.

Most mammographers already hold ARRT(M) certification, which covers the foundational knowledge for breast imaging. However, DBT-only facilities increasingly expect or require completion of the 8-hour DBT training mandated by the Mammography Quality Standards Act (MQSA). If you completed this training years ago when your facility first introduced tomo, you are likely still compliant — MQSA does not currently require recurring DBT-specific continuing education beyond general mammography CE.

That said, many employers now look for:

• Documented DBT training completion within the last five years, even if not legally required
• Hands-on tomosynthesis experience — at least 100-200 DBT exams performed independently
• Familiarity with synthesized 2D workflows and quality control protocols specific to tomo systems
• Competency assessments that include DBT positioning, compression techniques, and troubleshooting

If you have been working in a facility where DBT was available but not routine, now is the time to log your tomo cases and seek additional hands-on training. Some facilities offer internal cross-training programs; others partner with vendors or professional organizations for refresher courses.

Workflow Changes You Will Notice

Switching to a DBT-only environment changes the rhythm of your day. Tomosynthesis acquisitions take slightly longer than conventional 2D mammography — usually an additional 4-7 seconds per view while the X-ray tube sweeps across the breast. That may not sound like much, but across a full schedule, it adds up.

You will also notice differences in:

• Positioning precision: Because DBT captures multiple slices, any motion or suboptimal positioning becomes more visible to the radiologist. Clean, centered, well-compressed images matter even more.
• Compression technique: Some patients tolerate the longer acquisition time well; others become anxious or move. Communication and reassurance skills become critical.
• Image review time: Radiologists spend more time reviewing tomo studies because they are scrolling through dozens of slices instead of viewing four static images. This can impact turnaround times for add-on views or same-day diagnostics.
• Data storage and transfer: DBT files are significantly larger than 2D mammograms. While this is mostly an IT concern, you may encounter longer upload times or occasional system slowdowns, especially in facilities with older PACS infrastructure.

Adapting to these workflow nuances takes practice. The more DBT exams you perform, the more efficient and confident you will become.

Training Resources and Skill-Building

If your current facility has not yet transitioned to DBT-only, or if you are preparing to apply for a role in a tomo-centric practice, seek out training opportunities now. Waiting until you are onboarding at a new job is not ideal — employers increasingly expect candidates to arrive with DBT competency already in place.

Here are some practical ways to build your skills:

• Vendor-sponsored training: Hologic, GE, Siemens, and other manufacturers offer free or low-cost DBT training modules, often available online. These cover system-specific workflows and quality control procedures.
• Professional society courses: The American Society of Radiologic Technologists (ASRT) and the Society of Breast Imaging (SBI) both offer continuing education focused on tomosynthesis best practices.
• Peer mentorship: If colleagues at your facility are already performing high volumes of DBT, ask to shadow them or request feedback on your positioning and technique.
• Simulation and case review: Some facilities use case-based learning sessions where mammographers review challenging DBT exams and discuss what could have been optimized.

The goal is not just to check a training box, but to develop genuine confidence and fluency with DBT workflows. Employers can tell the difference.

Career Mobility and Market Demand

As more facilities adopt DBT-only protocols, mammographers with strong tomosynthesis skills are in high demand. This is especially true for travel and per diem roles, where facilities expect technologists to hit the ground running with minimal orientation.

If you are considering a job change, highlighting your DBT experience — number of exams performed, systems you have worked on, and any advanced training — can set you apart. Facilities transitioning to tomo-only workflows often seek out experienced mammographers who can help train the rest of the team.

Conversely, if you have limited DBT exposure, you may find your options narrowing in certain markets. Urban imaging centers and academic medical centers are leading the shift, while some rural or community facilities may take longer to transition. Understanding where you want to work — and what those facilities expect — will help you target your skill development strategically.

What This Means for You

The move to DBT-only mammography is not a distant future trend — it is happening now, in 2026, across the country. For mammographers, this shift represents both a challenge and an opportunity. By proactively building your tomosynthesis skills, ensuring your credentials are current, and understanding the workflow implications, you position yourself as a confident, capable professional ready to thrive in modern breast imaging environments.

Whether you are staying at your current facility as it transitions or exploring new opportunities, the time to prepare is now. DBT is not just another modality — it is becoming the standard of care, and your expertise will be what keeps patients safe, comfortable, and well-served.
