Device for facilitating lesion localization in breast biopsies.
E. Mark Levinsohn · Radiology · 1991
To allow easier radiographic localization and pathologic correlation of occult lesions in breast biopsies, a specimen holder composed of two Plexiglas plates was devised. The specimen is compressed between the plates and radiographed. The lesion can be localized by inserting a 22-gauge needle through the appropriate hole in the bottom plate. Holes are centered within alpha numerically labeled squares on a grid created by grooves on the plates. The grooves allow the pathologist to excise only the tissue with the lesion.
