From: T1 and T2 mapping for identifying malignant lymph nodes in head and neck squamous cell carcinoma
Images show a 7.9-mm size benign lymph node (arrows) at right level II from a 49-year-old male with hypopharyngeal cancer (the same patients in Fig. 2). (A) Contrast-enhanced T1-weighted image shows the lymph node (arrow). (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 (0.698 × 10− 3mm2/s). (D) T1 mapping and (E) T2 mapping show a T1 value of 1746.1 ± 115.1 ms and a T2 value of 92.0 ± 9.7 ms. (F) Section through the same lymph node showing absence of metastasis
