Description

<p>Sentinel lymph node biopsy (SLNB) using magnetic tracers is a promising technique in the treatment of breast cancer to evaluate the presence of metastasis in sentinel lymph nodes (SLNs). Selection of the first SLN, which contains the largest amount of iron of magnetic nanoparticles, in some resected nodes can help to investigate the metastasis because cancer most likely metastasizes to that node. However, iron distributions in SLNs of varied sizes (generally 3-20 mm) are unidentified.In this study, we developed a device can quantify iron amount in SLNs without the dependencies of the distributions and sizes. The device, currently, quantified the iron in magnetic phantoms that is the size of 3-20 mm with varied iron-distributions, within the error of 10%. These results indicate the developed device is useful for quantifying the magnetic nanoparticles accumulating in SLNs.</p>
