Fig 3. Follicular adenoma. A and B, Axial T1- and T2-weighted MR images, respectively, showing a well-defined more or less oval solitary nodule affecting the right thyroid lobe with contralateral tracheal displacement. The nodule has an anterior cystic part (arrow) and another posterior solid one (arrowhead). C, An ADC map image with marked hyperintensity of the anterior cystic portion of the nodule (arrow), denotes increased diffusion with a measured ADC value of 2.25 ± 0.18 x 10–3 mm2/s and a relatively hypointense posterior solid portion (arrowhead), denotes relatively restricted diffusion with a measured ADC value of 1.2 ± 0.08 x 10–3 mm2/s.
