RadteraUltrasound Breast (Targeted / Diagnostic)
USNo contrastBreast
Indications
- Palpable breast lump
- Targeted evaluation of mammographic abnormality
- Characterize cyst vs solid
- Evaluation in dense breasts / young or pregnant patients
- Guidance for biopsy / aspiration
- Axillary lymph node evaluation
Patient prep
- None
- Supine/oblique with ipsilateral arm raised above head
Contrast
None / non-contrast
Technique
- High-frequency linear transducer 12-18 MHz
- Scan area of concern in two orthogonal planes (radial and antiradial)
- Document lesion location by clock position and distance from nipple, plus depth
- Color Doppler for vascularity; evaluate ipsilateral axilla as needed
Series / Sequences
| # | Series / Sequence | Plane | Notes |
|---|---|---|---|
| 1 | Lesion - radial and antiradial (or long/transverse) | Two orthogonal planes | Measure 3 dimensions; shape, orientation, margin, echo pattern, posterior features (BI-RADS) |
| 2 | Lesion annotation | As needed | Clock position, distance from nipple, depth |
| 3 | Color Doppler of lesion | As needed | Vascularity |
| 4 | Ipsilateral axilla (if indicated) | As needed | Abnormal nodes - cortical thickening, loss of fatty hilum |
Key points
- Characterize and report using ACR BI-RADS US lexicon (shape, orientation, margin, echo pattern, posterior acoustic features)
- Simple cyst: anechoic, circumscribed, posterior enhancement, imperceptible wall — BI-RADS 2
- Suspicious features: non-parallel (taller-than-wide) orientation, irregular shape, angular/spiculated margins, posterior shadowing
- Always annotate clock position, distance from nipple, and depth; evaluate axilla for suspicious masses
