Summary
Preoperative breast lesion localization methods vary by practice type. Academic centers more frequently use wireless localization devices, suggesting potential barriers for smaller, less specialized practices in adopting new techniques.
Area of Science:
- Radiology
- Medical Imaging
- Breast Imaging
Background:
- Preoperative needle localization is crucial for guiding breast and axillary lesion excision.
- Understanding current trends and influencing factors in localization practices is essential for optimizing patient care.
Purpose of the Study:
- To investigate contemporary trends in preoperative breast and axillary needle localizations.
- To identify factors influencing the adoption of various localization practice patterns.
Main Methods:
- A 14-question web-based survey was distributed to Society of Breast Imaging physicians.
- Survey responses were analyzed using descriptive statistics and inferential tests (Pearson's chi square, ANOVA).
- Practice type, number of radiologists, and fellowship training were assessed for correlation with localization methods.
Main Results:
- A 19.1% response rate (401/2097) was achieved, with diverse practice settings represented.
- Radioactive seed use correlated significantly with practice type; academic practices were more likely users.
- Wireless localization device adoption was associated with a higher number of mammography readers and fellowship-trained breast radiologists.
Conclusions:
- Breast and axillary lesion localization techniques differ significantly across practice types.
- Academic practices show a higher propensity for utilizing wireless localization devices.
- Potential barriers may exist for smaller or less specialized practices in adopting advanced localization modalities.
