ABSTRACT
When a lesion has been discovered by breast MRI and a histological diagnosis is considered to be necessary, it is worth reviewing the mammogram and undertaking a breast ultrasound examination of the relevant area of breast. Careful study may show a feature that had been overlooked, which will enable a biopsy to be obtained or a localizing wire to be inserted. Colour flow or power Doppler ultrasound may be worth trying, as lesions with high vascularity may stand out from the background tissue with these techniques (Sabel and Aichinger 1996). Some lesions of this nature can be shown and localized by contrast-enhanced CT (Heywang-Kobrunner et al 2000). The extent to which
such attempts will be taken will depend on whether there is ready access to an MRI localizing device.
