Localisation of breast lesions with MR mammography (work-in-progress)

While working with dynamic MR mammography (MRM) the need for an MR-guided localisation technique became obvious, because certain lesions were only detectable with dynamic MRM. We developed a technique to mark small breast lesions with MR guidance. Contrast-enhanced MRI was performed in a second examination, and with the use of markers on the skin a needle was placed next to the lesion. A charcoal mixture was injected around the lesion. We performed this procedure in five patients. Follow-up examinations have shown that the procedure was successful.
