From: T1 and T2 mapping for identifying malignant lymph nodes in head and neck squamous cell carcinoma
Images show a 7.5-mm size metastatic lymph node (arrows) at left level II from a 49-year-old male with hypopharyngeal squamous cell carcinoma. (A) Contrast-enhanced T1-weighted image shows the lymph node. (B) DWI with a b-value of 800 mm2/s shows a hyperintense area. (C) The ADC map on the targeted lymph node shows a hypointense signal, an ADC value of 0.831 × 10− 3 mm2/s. (D) T1 mapping and (E) T2 mapping show a T1 value of 1708.2 ± 216.6 ms and a T2 value of 76.6 ± 11.0 ms. (F) Section through the same lymph node showing metastatic deposit
