How to Survey a Breast with Implants using Ultrasound
A Practical Guide for Breast Imaging Professionals
Breast implants add an extra layer to ultrasound imaging—but with the right technique and a systematic approach, you can obtain a thorough and confident evaluation.
Whether you’re scanning for routine assessment, focal symptoms, or implant integrity, this guide walks you through a clear, reproducible method to survey the augmented breast.
Understanding Implant Types and Placement
Before you even pick up the probe, it’s helpful to know what you’re working with.
Implant types:
Saline
Silicone (including cohesive gel)
Implant locations:
Subglandular (above the muscle)
Subpectoral / retropectoral (below the muscle)
Dual plane (partially under muscle)
Why it matters:
Implant type and position directly affect how sound waves travel and what anatomy you’ll visualize clearly.
Probe Selection and Machine Setup
Use a high-frequency linear transducer (10–15 MHz) for optimal resolution.
Adjust depth to include skin → implant → posterior tissues.
Apply harmonic imaging and compound imaging if available.
Reduce overall gain slightly to avoid “blooming” within silicone.
Tip: Silicone can create internal echoes—don’t mistake these for pathology.
Patient Positioning
Supine or slight oblique position
Arm raised on the side being scanned
Use a wedge or towel under the patient if needed to flatten the breast
Goal: Spread tissue evenly over the implant for better visualization.
Systematic Scanning Technique
Consistency is everything.
1. Start with radial images showing the outer of the implant around the breast.
Typical clocks to note, (Company dependent) 12:00, 3:00, 6:00, 9:00 and an overall image of the implant dropping your depth to see the bottom of the implant at the chest wall.
2. Evaluate Tissue Planes
Identify and assess:
Skin
Subcutaneous fat
Breast parenchyma
Implant capsule
Implant interior
Posterior tissue (especially if subpectoral)
The Implant Itself: What to Look For
A normal implant should appear:
Anechoic (saline) or low-level echoes (silicone)
Smooth, well-defined capsule
Assess for:
1. Implant Integrity
Stepladder sign → intracapsular rupture
Snowstorm appearance → extracapsular rupture
2. Capsular Contracture
Thickened capsule
Irregular contour
Decreased implant compressibility
3. Peri-implant Fluid
Small amounts can be normal early post-op
Larger or post-op persisting collections may need further evaluation
Don’t Miss the Tissue in Front… or Behind
A common mistake is focusing too much on the implant and missing breast tissue.
Make sure to:
Fully evaluate anterior parenchyma
Apply gentle compression or repositioning to improve visualization
Evaluate the Axilla
Always include:
Axillary lymph nodes
Tail of Spence
Look for:
Cortical thickening
Loss of fatty hilum
Abnormal vascularity
Common Pitfalls to Avoid
Mistaking silicone artifact for pathology
Not adjusting depth appropriately
Ignoring subtle peri-implant fluid
Failing to correlate with patient symptoms
When to Recommend Additional Imaging
Ultrasound is powerful—but not perfect.
Consider further evaluation when:
Suspected implant rupture (especially silicone)
Unclear mass or distortion
Persistent or unexplained peri-implant fluid
MRI is often the next step for implant integrity.
Final Thoughts
Scanning breasts with implants isn’t harder—it just requires intention.
A structured approach, awareness of implant-specific findings, and careful attention to all tissue planes will dramatically improve both your confidence and diagnostic accuracy.
The key?
Slow down, stay systematic, and never let the implant distract you from the breast tissue itself.
If you’re building your skillset, this is a high-value techniques to master—because your patients are counting on you to see what others might miss.
