Post-injection (1.0 ml) T1-weighted coronal images of the anterior upper trunk. A Image after tracer injection. Lymphatic uptake towards upper body is indicated with the white arrows and lymphatic uptake towards groins is indicated with the black arrows. B Image showing a large decrease in signal in groin lymph vessels. C Image of lymphatic tracer uptake in both groin LNs, five minutes post-injection. The first LN showing a large decreased signal and therefore considered to be the SLN, indicated with the black circle
