Photoacoustic and MR image comparison of all resected lymph nodes with contrast injection. As shown in lymph node 1 (white dotted line), the PA response pattern is comparable with the location of MRI signal decrease. Some nodes show a continuous contrast band throughout their periphery (1,5), while others show some small irregularities (4,6). The figure was reused from the research article published in the journal Contrast Media and Molecular Imaging by Grootendorst and co-workers in 2013 [190]
