Images obtained from a 77-year-old male illustrate false negative conventional native MRI (a T2W-STIR). True positive findings showing a small signal enhancement with contrast (b CET1WFS), increase with diffusion restriction can be seen in the axial original DW image (c, d, b-value: 1,000 s/mm2) and the corresponding signal decrease in the ADC map (e), which measured 0.773 × 10−3 mm2/s in the PT and 0.771 × 10−3 mm2/s in the LN.
