Figure 2. Specimen radiograph. It demonstrates the RFID tag (T) adjacent to the hydrogel marker (H) in a patient who received NACT. The histology showed that the DCIS and the margins were clear. Titanium clips have been placed for orientation: 1 for superior (S); 2 for medial (M); 3 for inferior (I). NACT: Neoadjuvant chemotherapy; RFID: radio-frequency identification.
