From: T1 and T2 mapping for identifying malignant lymph nodes in head and neck squamous cell carcinoma
Images show a 5.0-mm size metastatic lymph node (arrows) at right level III from a 63-year-old female with oral cavity squamous cell carcinoma. (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 (1.003 × 10− 3mm2/s). (D) T1 mapping and (E) T2 mapping show a T1 value of 1434.3 ± 148.8 ms and a T2 value of 64.4 ± 4.1 ms. (F) Section through the same lymph node showing metastatic deposit
