Summary
Pacemaker pulse generators can obscure mammograms in women, potentially interfering with breast cancer screening. Alternative placement may be considered for high-risk patients to ensure clear imaging.
Area of Science:
- Radiology
- Cardiology
- Oncology
Background:
- Screening mammography is crucial for early breast cancer detection in women.
- Pacemaker pulse generators are often implanted in the pectoral region.
- The impact of pectoral pulse generators on mammogram quality is not well-documented.
Purpose of the Study:
- To evaluate the interference of pectoral pulse generators with screening mammography in female patients.
- To determine the frequency of mammogram obstruction by pulse generators.
- To provide recommendations for managing pacemaker placement in relation to mammography.
Main Methods:
- Retrospective review of mammograms from 74 female pacemaker recipients aged 40 and older.
- Assessment of mammogram quality and identification of any obstructions caused by pulse generators.
Main Results:
- The pulse generator obscured a portion of the mammogram in 7 out of 74 patients (12%).
- This obstruction could potentially hinder the detection of abnormalities.
Conclusions:
- Pectoral pulse generator placement can interfere with screening mammography in women.
- Consideration should be given to potential mammographic interference during pacemaker implantation.
- Baseline mammography review and, for high-risk individuals, non-conventional pulse generator locations may be appropriate.
