MRI Breast With and Without Contrast — Dictation, Appropriateness, and Dose for Residents

1. The High-Stakes Breast MRI Read

It’s a Tuesday afternoon. You pick up the next case: a 42-year-old for high-risk screening breast MRI, BRCA1 positive. The mammogram was negative, but the breasts are extremely dense. Your attending expects a perfect BI-RADS assessment, a comment on background parenchymal enhancement, and a full kinetic and morphologic analysis of that tiny 6 mm focus of non-mass enhancement in the upper outer quadrant. Getting the details right on these reads is non-negotiable—it directly impacts surgical planning and patient outcomes.

As a resident, I remember the pressure of these cases. You have to be systematic, confident, and fast. This guide is built for that moment—to give you a solid framework for dictating breast MRI, whether you’re a PGY-2 on your first breast rotation or a fellow fine-tuning your reports.

2. What an MRI Breast With and Without Contrast Covers and What Attendings Look For

A breast MRI is not a routine screening tool for the general population; it’s a high-sensitivity problem-solver. It’s the go-to for high-risk screening, evaluating the extent of a newly diagnosed cancer, and assessing response to treatment. It excels at finding cancers that might be hidden on mammography, especially in dense breast tissue.

When your attending reviews your report, they are looking for a systematic evaluation that answers specific clinical questions:

• High-Risk Screening: Is there a new or suspicious enhancing lesion in a patient with a strong family history (e.g., BRCA mutation) or prior chest radiation?
• Extent of Disease: For a newly diagnosed cancer, is the disease unifocal? Is there multifocal (multiple tumors in one quadrant) or multicentric (multiple tumors in different quadrants) disease? Is there a contralateral cancer?
• Problem Solving: For equivocal findings on mammography or ultrasound, does MRI clarify the finding?
• Neoadjuvant Therapy Response: How has the tumor responded to chemotherapy before surgery?
• Recurrence: Is there enhancement in the lumpectomy bed concerning for recurrence?
• Implant Integrity: (Note: This typically requires a dedicated non-contrast protocol with silicone-sensitive sequences, but is a common indication for breast MRI).

Your report must methodically address these points, culminating in a clear Breast Imaging Reporting and Data System (BI-RADS) assessment for each breast.

3. Radiology Report Template for MRI Breast With and Without Contrast

This template provides a solid starting point. You can adapt it for your institution’s macros in PowerScribe or other dictation software. The key is to be consistent and thorough.

Technique

Bilateral breast MRI was performed with and without intravenous contrast on a [1.5T or 3T] scanner using a dedicated breast coil. The patient was imaged in the prone position. Pre-contrast sequences included T1-weighted, T2-weighted fat-suppressed, and diffusion-weighted images. Following the administration of [x] mL of [contrast agent name], dynamic post-contrast T1-weighted fat-suppressed images were obtained. Subtraction images were generated. The study was compared to [prior studies].

Findings

Fibroglandular Tissue: The breasts are [almost entirely fatty / scattered fibroglandular / heterogeneously dense / extremely dense].

Background Parenchymal Enhancement (BPE): [Minimal / Mild / Moderate / Marked]. The BPE is [symmetric / asymmetric].

RIGHT BREAST:
[Describe any mass, non-mass enhancement, or focus. Use the BI-RADS lexicon: location (quadrant, clock face, depth), size, shape (oval, round, irregular), margin (circumscribed, irregular, spiculated), internal enhancement characteristics (homogeneous, heterogeneous, rim enhancement), and kinetics (Type 1 persistent, Type 2 plateau, Type 3 washout).]
Example: At the 2 o’clock position, [x] cm from the nipple in the middle depth, there is a [size] cm irregular mass with spiculated margins. It demonstrates heterogeneous internal enhancement and Type 3 washout kinetics.
No other suspicious mass, non-mass enhancement, or architectural distortion.

LEFT BREAST:
[Describe any mass, non-mass enhancement, or focus using the same BI-RADS lexicon as above.]
No suspicious mass, non-mass enhancement, or architectural distortion.

AXILLAE:
No axillary, internal mammary, or supraclavicular lymphadenopathy. [If lymph nodes are present, describe their location (Level I, II, III), size, and morphology (e.g., cortical thickening, loss of fatty hilum).]

OTHER FINDINGS:
The visualized chest wall, lung apices, and upper abdomen are unremarkable. [Note any incidental findings like sternal lesions, liver lesions, etc.]

Impression

1. [Finding 1, e.g., A [size] cm irregular, spiculated mass in the right breast at 2 o’clock, highly suspicious for malignancy.]
2. [Finding 2, e.g., No suspicious findings in the left breast.]
3. [Finding 3, e.g., No axillary adenopathy.]

BI-RADS ASSESSMENT:
Right Breast: BI-RADS 5 – Highly Suggestive of Malignancy.
Left Breast: BI-RADS 1 – Negative.

RECOMMENDATION:
Ultrasound-guided biopsy of the right breast mass is recommended.

4. Free Template Sources for Radiology Residents

Building your own template library is a rite of passage. But you don’t have to start from scratch. If you’re looking for more examples or templates for other modalities, two great free repositories exist that are curated by and for radiologists:

• RadReport.org: Maintained by the Radiological Society of North America (RSNA), this is a comprehensive library of peer-reviewed templates covering nearly every study imaginable.
• Radiology Templates (AU): An excellent, straightforward resource maintained by Australian radiologists, with clean, practical templates.

Bookmark these. They are invaluable on call when you encounter a study you haven’t dictated in a while.

5. The Next-Level Move: AI-Assisted Structured Reporting

Once you’re comfortable with the basic structure, the next step is improving speed and consistency without sacrificing quality. This is where AI tools can make a significant difference. Instead of manually clicking through a structured report or editing a macro, you can dictate your positive findings in free form and let the software handle the rest.

For example, you’d simply dictate, “Irregular 2 cm mass in the left upper outer quadrant with spiculated margins and rapid washout kinetics.” Tools like GigHz Precision AI are designed to parse that natural language and automatically populate a complete, BI-RADS-compliant structured report. It helps ensure you never miss a key descriptor and that your final impression aligns perfectly with your findings. It’s about streamlining the tedious parts of reporting so you can focus on the diagnostic challenge.

6. When Should You Order an MRI Breast With and Without Contrast? ACR Appropriateness Criteria

Knowing when breast MRI is the right test is as important as reading it correctly. The American College of Radiology (ACR) provides evidence-based guidelines. For breast imaging, MRI is a powerful tool but is reserved for specific clinical scenarios.

For high-risk screening in women with a ≥20% lifetime risk, a known BRCA gene mutation, or a history of chest radiation between ages 10 and 30, annual breast MRI is Usually Appropriate as a supplement to annual mammography, as outlined in the ACR’s “Female Breast Cancer Screening” guidelines.

In the context of a newly diagnosed invasive breast cancer, breast MRI is Usually Appropriate for evaluating the locoregional extent of disease in both early-stage (I-IIA) and late-stage (IIB-III) presentations. This helps surgeons plan for breast-conserving therapy versus mastectomy and can identify otherwise occult disease in the ipsilateral or contralateral breast.

For surveillance after treatment, the guidelines vary. For a patient with a history of breast-conserving therapy (lumpectomy), annual MRI is Usually Appropriate. If a patient has symptoms or physical exam findings concerning for local recurrence after either lumpectomy or mastectomy, MRI is also Usually Appropriate to evaluate the concern.

Finally, when monitoring a patient’s response to neoadjuvant chemotherapy, breast MRI is Usually Appropriate for the initial assessment of tumor size and extent before starting therapy. These guidelines ensure that this high-sensitivity exam is deployed where it can most significantly impact patient care.

7. MRI Breast With and Without Contrast Imaging Protocol — Phases, Contrast, and Technical Details

A high-quality breast MRI depends on a meticulously executed protocol. Patient motion is the enemy, as pre- and post-contrast images must be perfectly registered for subtraction to work. The dynamic contrast-enhanced (DCE) portion is the core of the exam, providing the kinetic data that helps differentiate benign from malignant enhancement.

Here is a typical protocol:

Common protocol pitfalls:

• 3T vs. 1.5T: 3T scanners provide higher signal-to-noise ratio (SNR), which is advantageous for the high-spatial-resolution dynamic imaging required for breast MRI. However, excellent diagnostic studies can be obtained on 1.5T magnets with an optimized protocol.
• DWI Role: Diffusion-weighted imaging is increasingly critical. Malignant lesions typically demonstrate restricted diffusion (high signal on high b-value images, low signal on ADC maps). Some institutions are exploring abbreviated MRI protocols for screening that rely heavily on DWI and the first post-contrast sequence to reduce scan time.
• Abbreviated MRI: An emerging concept for screening, this protocol shortens the exam to just a pre-contrast, an early post-contrast, and sometimes a delayed sequence. The goal is to reduce scan time and cost while retaining most of the diagnostic sensitivity for invasive cancers.
