From: Mediastinal lymphadenopathy in sarcoidosis: Can diffusion MRI play a role in its evaluation?
a Axial T1WI, b axial T2WI, c, e diffusion-weighted MRI image, d, f ADC map showing exuberant partially amalgamated mediastinal lymphadenopathy seen predominantly involving the paratracheal, bilateral hilar and subcarinal lymph node groups as well as prevascular, retrosternal and retrocaval lymph node groups. They display intermediate T1 WI, intermediate to hyperintense T2 WI, hyperintense on DWI and mixed signal on ADC map with mean ADC value of 2.1 × 10−3 mm2/s
