Contrast-enhanced spectral mammography (CESM)-guided breast biopsy as an alternative to MRI-guided biopsy
1Nottingham Breast Institute, Nottingham University Hospitals, Nottingham, UK.
Objective:
Contrast-enhanced spectral mammography (CESM) breast biopsy has been recently introduced into clinical practice. This short communication describes the technique and potential as an alternative to MRI-guided biopsy.
Methods And Materials:
An additional abnormality was detected on a breast MRI examination in a patient with lobular carcinoma. The lesion was occult on conventional mammography, tomosynthesis and ultrasound and required histological diagnosis. Traditionally, this would have necessitated an MRI-guided breast biopsy, but was performed under CESM guidance.
Results:
A diagnostic CESM study was performed to ensure the lesion visibility with CESM and then targeted under CESM guidance. A limited diagnostic study, CESM scout and paired images for stereotactic targeting were obtained within a 10 min window following a single injection of iodinated contrast agent. The time from positioning in the biopsy device to releasing compression after biopsy and marker clip placement was 15 min. The biopsy confirmed the presence of multifocal breast cancer.
Conclusion:
CESM-guided breast biopsy is a new technique that can be successfully used as an alternative to MRI-guided breast biopsy.
Advances In Knowledge:
CESM-guided biopsy can be used to sample breast lesions which remain occult on standard mammography and ultrasound.
