Twenty-two-year-old female patient with nodular goiter. a Axial T1. b Axial T1 with contrast. df Axial diffusion-weighted imaging with b values: 50, 400, 800, and 1000 respectively. g ADC map (gray). h ADC map (colored) showed multiple thyroid nodules detected in both thyroid lobes, the largest at right thyroid. The nodules showed high signal intensity in T1 and peripheral ring enhancement after IV contrast. It elicited high signal in DWI, in low b values, with rapid signal decayed in high b values, showing the same signal intensity of normal thyroid tissue at b value 1000, with corresponding high signal intensity at ADC map (free diffusion), ADC value = 2.21 × 10−3 s/mm2 (high)
