An iron oxide liquid injected into the breast that travels to the first lymph nodes, where a magnetic probe finds them during surgery. It does the job of the radioactive tracer without radioactivity.
The FDA approved Endomag's Magtrace and Sentimag magnetic localization system by PMA (P160053, 24 July 2018) under product code PUV, lymph node location system during sentinel biopsy procedure, a class III device; a supplement of 15 April 2024 continues the line. Mammotome, part of Danaher, now sells it after acquiring Endomag. Because the tracer is not radioactive, no nuclear medicine department is needed to give it.
Superparamagnetic iron oxide nanoparticles injected near the tumour drain through lymphatics and are retained in the first nodes; a handheld magnetometer probe detects them in theatre.
A blue dye injected near a tumour before surgery. It travels to the nearest lymph nodes and stains them blue, helping the surgeon find the sentinel node.
