Let’s Talk Breast Health: Mammograms, Ultrasound, MRI, QT Scans, and Thermography
“I’ve heard about a few different breast scans. Can we talk about them?”
Absolutely.
Maybe you want to understand the difference between a regular mammogram and a 3D mammogram. Perhaps your report mentioned dense breasts, and you’re wondering whether ultrasound would give you more information. You may be curious about thermography or the QT breast scan available in St. Petersburg.
You should feel comfortable asking about any of them.
You can appreciate the value of screening and still have questions about compression, radiation, contrast, cost, or what an appointment feels like. Those questions help us understand what matters to you.
For Breast Cancer Awareness Month, let’s make room for a calm, practical conversation about your breast imaging options.
You don’t need to become an imaging expert. You deserve enough information to feel comfortable participating in your care.
Your breast health plan can be personal
Your friend’s screening routine may look different from yours. That can be appropriate.
Age, breast density, family history, previous imaging, and personal medical history all help shape a plan. Your comfort and preferences also belong in that discussion.
The American Cancer Society estimates that approximately 1 in 8 women in the United States will develop breast cancer during her lifetime. There is encouraging news, too: the five-year relative survival rate for breast cancer diagnosed while still confined to the breast is greater than 99%. These are population statistics, and individual experiences vary. [1,2]
Screening and timely follow-up are ways to care for your future health. Understanding the process can make taking that next step feel more manageable.
Screening versus diagnostic imaging: what is the difference?
Screening means checking for cancer when you have no symptoms.
Diagnostic imaging means taking a closer look at a particular concern. That might be a change you noticed or something the radiologist wants to clarify after a screening examination.
“Diagnostic” describes the purpose of the appointment. It does not mean you have received a cancer diagnosis.
Similarly, being called back for additional pictures means more information is needed. It is not, by itself, a cancer diagnosis. [3]
When scheduling, tell the office whether you are due for routine screening or have a specific concern. That helps them arrange the right appointment.
Mammograms: a familiar starting point
A mammogram uses low-dose X-rays to create images of the inside of the breast.
It can show tissue changes, masses, and tiny calcium deposits called calcifications. Some changes are visible on imaging before they can be felt.
Mammography is an established breast cancer screening method with evidence supporting a reduction in breast cancer deaths. [3,4]
During the examination, the breast is briefly compressed to spread the tissue and create a clearer image.
Your comfort belongs in the conversation. Tell your technologist about previous discomfort, tenderness, implants, or difficulty with positioning. They can explain each step and work with you throughout the examination.
What makes a mammogram “3D”?
A standard 2D mammogram produces flat images from different views.
A 3D mammogram, also called digital breast tomosynthesis, captures images from several angles. A computer reconstructs thin sections that the radiologist can examine.
This helps separate overlapping tissue. Compared with 2D mammography alone, 3D imaging can detect additional cancers and reduce callbacks for more pictures. It may be particularly helpful for some women with dense breasts. [5]
Both 2D and 3D mammography use low-dose radiation and breast compression. Either can be performed for screening or diagnostic purposes.
“I have dense breasts. What does that mean?”
This is a common question.
Approximately half of U.S. women over 40 have dense breast tissue. Density describes how much fibrous and glandular tissue appears on a mammogram compared with fatty tissue. It is not something you can reliably determine from breast size or touch.
Dense tissue can make some findings harder to see on mammography and is also associated with increased breast cancer risk. [6]
A density notification gives you information to discuss with your care team.
Depending on your history and density, your clinician or breast radiologist may discuss supplemental ultrasound, MRI, or another examination. Together, you can consider what additional information it may provide and whether it is appropriate for you.
Breast ultrasound: a closer look with sound waves
Breast ultrasound uses sound waves to create images without ionizing radiation.
You lie on an examination table while a technologist or radiologist moves a probe over the skin with gel. Ultrasound can help characterize an area seen or felt in the breast, including whether a finding is fluid-filled or solid.
You may hear these terms:
Targeted ultrasound: Examines a specific area.
Whole-breast ultrasound: Evaluates a broader area, sometimes as supplemental screening.
Automated breast ultrasound, or ABUS: Uses a system to acquire a standardized series of breast images.
Ultrasound and mammography show different details, which is why they are often used together. Certain findings, including some calcifications, are better assessed with mammography. [7]
The type of ultrasound recommended depends on whether the goal is to evaluate a particular concern or provide supplemental imaging.
Breast MRI: detailed information for a personalized plan
Breast MRI uses a magnetic field and radio waves rather than ionizing radiation.
You generally lie face down on a padded table with your breasts positioned in a dedicated imaging device. MRI used to detect breast cancer usually includes intravenous gadolinium contrast.
It may be part of screening for women at higher risk or used to answer a particular clinical question. For some women, the recommended plan includes both MRI and mammography. [8,9]
An abbreviated breast MRI uses a shorter imaging protocol. It usually still includes contrast and may be available for selected supplemental screening situations. [17]
If enclosed spaces make you uncomfortable, tell the imaging team beforehand. They can explain the examination and discuss ways to support your comfort.
Your team also reviews contrast suitability, implanted devices, kidney health, and other relevant considerations. An MRI performed to assess silicone implant integrity may use a different protocol from an MRI performed to look for breast cancer.
QT breast scans: a different imaging experience
You may have heard about the QT breast scan, also called breast acoustic CT.
Despite “CT” appearing in its name, QT imaging uses ultrasound technology rather than the X-rays used in conventional CT.
During the scan, you lie face down while the breast rests in a warm water bath. The system collects sound-wave information from around the breast to create three-dimensional images.
The examination uses:
No ionizing radiation
No breast compression
No injected contrast
Those features may appeal to women exploring a different scanning experience.
The QT breast scan is an FDA-cleared ultrasound technology that creates three-dimensional images and can measure the amount of fibroglandular tissue in the breast. It can provide additional imaging information within an individualized care plan; its FDA labeling specifies that it does not replace screening mammography. [10]
Locally, Divine Breast Imaging in St. Petersburg offers QT scanning.
As with any breast imaging appointment, having previous reports and images available can help the interpreting clinician understand your history and coordinate appropriate follow-up.
Thermography: understanding thermal patterns
Thermography uses an infrared camera to record temperature patterns at the skin’s surface.
Image capture involves no radiation, compression, or physical contact. Some women choose it as an additional wellness assessment because they are interested in this different type of information.
Thermography offers a different perspective from structural breast imaging. Mammography, ultrasound, and MRI depict internal tissue, while thermography records surface heat patterns.
Women who choose thermography can include it in a broader wellness conversation while continuing recommended breast screening. Thermography does not diagnose or rule out breast cancer and is not a substitute for mammography. [11]
At Live In Vitality Wellness Center, we host thermography sessions in Brandon, FL through Florida Medical Thermography. Their team performs the imaging, with reports interpreted independently.
You can view dates and booking options on the Florida Medical Thermography scheduling page.
Keeping your reports together makes it easier to discuss findings with your healthcare team and maintain a coordinated breast health plan.
Additional breast imaging options you may encounter
Contrast-enhanced mammography
Contrast-enhanced mammography, or CEM, combines mammographic X-ray imaging with intravenous iodinated contrast. It provides information about contrast enhancement that may help identify or evaluate abnormalities.
It may be considered in selected circumstances, including when MRI is unsuitable. It involves compression and radiation. Your imaging team reviews relevant contrast reactions, kidney health, and other precautions. [12]
Molecular breast imaging
Molecular breast imaging, or MBI, uses an injected radioactive tracer and specialized cameras to assess patterns of tracer uptake.
It may help answer selected questions or provide supplemental evaluation when other options are unsuitable. It involves radiation and is not a routine replacement for mammography. [13]
AI-assisted interpretation
Some facilities use artificial intelligence to help radiologists assess images or prioritize findings. AI is an interpretation aid rather than a separate breast examination.
The technology works within the facility’s interpretation process, with qualified clinicians responsible for reviewing findings and recommending next steps.

When should you begin breast cancer screening?
Recommendations vary somewhat between professional organizations.
For women at average risk:
The U.S. Preventive Services Task Force recommends mammography every two years from ages 40 through 74. [4]
The American College of Radiology recommends annual mammography beginning at 40 and a breast cancer risk assessment by age 25. [14]
A risk assessment by 25 is a conversation about your history. It does not mean everyone needs imaging at that age.
A personal history of breast cancer, certain inherited gene variants, previous chest radiation, or other factors may lead to a different plan.
If you notice a new breast change, you can seek an evaluation at any age.
Getting to know your breasts at home
Breast awareness can be simple. Become familiar with what is usual for you without feeling pressure to perform a perfect examination.
Let your provider know if you notice:
A new lump in the breast or underarm
A new change in breast size or shape
Skin dimpling or puckering
A nipple that has newly turned inward
Nipple discharge that occurs without squeezing, especially bloody or clear discharge
Persistent discomfort in one specific area
Persistent redness, swelling, or thickening of the breast skin
Many breast changes have benign explanations. An evaluation can help you understand what is happening and whether follow-up is needed.
Awareness at home and a clinician’s examination work alongside appropriate imaging. If a change persists, follow up even if your last screening result was normal. [15]
If you are asked to come back, here is what happens next
Breast imaging reports often include a BI-RADS assessment, a standardized way to describe findings and recommend follow-up.
That recommendation may be to:
Continue routine screening
Obtain additional pictures or a different type of imaging
Repeat imaging after a shorter interval
Have a biopsy to obtain more information
A biopsy collects a small tissue sample for laboratory analysis. A recommendation for one does not, by itself, establish a cancer diagnosis. [16,18]
Before the process is complete, make sure you know the recommended next step, when it should happen, and who will contact you with results.
You deserve clear explanations throughout your care.
