Primary endpoint: localization success of wire- and magnetic-seed-guided localization
| Successful localization | Magnetic seed | Wire | P | ||||
|---|---|---|---|---|---|---|---|
| Stereo (n = 282) | US (n = 664) | Total (n = 946) | Stereo (n = 337) | US (n = 833) | Total (n = 1170) | ||
| No | 2 (0.7) | - | 2 (0.2) | 8 (2.4) | 3 (0.4) | 11 (0.9) | 0.048 |
