Figure 1

Axial T1-weighted fat-suppressed contrast MRI images of grade 0–2 extranodal extension (ENE) in four stage II nasopharyngeal carcinoma patients. (A) Grade 0: without ENE; (B) Grade 1: lymph node (LN) infiltrating surrounding fat; (C) Grade 2: matted LNs; and (D) Grade 3: LN infiltrating sternocleidomastoid muscle (wight arrows).

Multidimensional nodal features of stage II nasopharyngeal carcinoma significantly associated with survival outcomes in univariate or multivariate analysis. Axial T2-weighted fat-suppressed image of (A) a 24-year-old man with one lymph nodes (LN) in level III; (B) a 56-year-old man with maximum diameter of lymph node 3.3cm; (C) a 50-year-old woman with four metastatic LNs; and (D) Sagittal T1-weighted fat-suppressed contrast images of a 45-year-old woman showing central nodal necrosis (CNN) (wight arrows). MAD = maximal axial diameter
