Figure 6.
Axial T1-weighted (T1w; VIBE DIXON) and T2-weighted (T2w; TSE DIXON, fat saturated) MR images and magnetic resonance elastography (MRE) magnitude, stiffness map and fluidity map of two small submandibular lymph nodes at level 1b on the left. A histologically confirmed malignant lymph node (bright white arrow) is stiffer than a benign lymph node (thin magenta arrow). Maximum diameter and fluidity did not differ between the two nodes. High stiffness and fluidity allow clear identification of the tumour extent. Scale; stiffness, red=stiff, blue=soft; fluidity, red=fluid, blue=solid.
