After injection of a magnetic tracer (Sienna+®, Endomagnetics ltd. UK), Sentimag® (Endomagnetics ltd. UK) is used as a magnetic handheld device to detect first draining lymph node(s) from from a primary tumor, referred to as sentinel lymph node. This dataset represents a look-up table (LUT) for Sentimag handheld probe, based upon Sienna+® samples. This LUT can be used to assess the amount of iron in dissected SLNs based tupon the magnetic readout (counts) Sentimag®.


The LUT was defined by acquiring six repeated magnetic measurements for ten 35µL Sienna+® samples with iron amount varying 1 – 504 µg (1.12µg, 5.04µg, 10.08µg, 28µg, 50.4µg, 100.8µg, 140µg, 280µg, 420µg and 504µg). A first order polynomial-fit is used to interpolate the relation between counts and iron content (in-house developed software using Matlab environment, R2020a, Mathworks, Inc., Natick, MA). The first column (A) of the data represents the iron content (µg), the corresponding counts for setting 1, 2 and 3 can be are found in the following columns respectively, B, C and D.
