Images obtained from a 54-year-old female illustrate a false positive interpretation error (arrows) on conventional MRI scans (a T1W, b T2W, c CET1WFS). On the axial trace DW image (d, b-value: 1,000 s/mm2), a signal increase can be seen without diffusion restriction on the ADC map (e), which measured 2.100 × 10−3 mm2/s in the radix linguae corresponding to inflammation and 0.834 × 10−3 mm2/s in the LN (f).
