a Surgical specimen sliced and photographed providing a finding-by-finding description where individual nodal structures are illustrated according to size, location, and type of pathology. N- in green denotes a benign lymph node, while N+ in red indicates a malignant lymph node. No other nodal structures, such as tumour deposits, were found in these 20 slices. b. The same finding-by-finding description as in (a) after joint comparison and consensus between the study radiologist and pathologist. Green colour indicates anatomically matched lymph nodes between histopathology and MRI of the surgical specimen; blue signifies lymph nodes found at histopathology but not in MRI of the surgical specimen; pink denotes lymph nodes found in MRI of the surgical specimen but not at histopathology
