Abstract:
Superparamagnetic iron oxide nanoparticles (SPIONs) are used as a tracer to find sentinel nodes in vivo. The principle that we use to locate them is Differential Magnetometry (DiffMag). In DiffMag, the nonlinear magnetic properties of SPIONs are used, enabling selective detection in the diamagnetic patient. We developed a prototype detector for surgical applications that is working with extremely small magnetic fields (~1 mT) and can detect the SPIONs in small quantities (~0.1 mg) inside patient tissue with the diamagnetic properties. We realized a novel magnetic technique to detect particles deep in the patient body, that is usable by the surgeon in a regular operating room. With this novel magnetic technique we aim to enable the application of the sentinel node procedure, in a much broader patient group.
