Summary

This single-center, retrospective study aims to evaluate the utility of the color Doppler twinkling artifact feature in improving the visibility of breast tissue marker clips within breast tissue and axillary lymph nodes. The study population will consist of approximately 86 female patients (with 110 clips) who have undergone placement of breast tissue marker clips and have corresponding preoperative imaging data from GE-10 or Siemens ultrasound systems between October 2024 and October 2025. The primary endpoint is the proportion of subjects whose implanted clips exhibit the characteristic "twinkling artifact" on color Doppler ultrasound imaging, reported with a 95% confidence interval.
