A lower number of SLN were visualized on the immediate scan using protocol A compared to protocol B (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001). Although a greater total number of nodes was excised using protocol A, this result was not statistically significant (<jats:italic>P<\/jats:italic>\u2009=\u20090.08).
