ABSTRACT:
The present invention involves the localization of lesion tissue within the breast. A surgical guidewire or needle includes a plurality of visual and radiopaque markers along its axial length so that the position of the lesion tissue may be determined in relation to the markers. In one form, the markers are portions extending from the guidewire or needle. In a second form, the markers are grooves formed in the guidewire or needle. The markers are disposed at predetermined distances of about one centimeter, and are differentiable so that the needle or guidewire serves as a metered marker perceptible in a mammogram or visually during surgery.
