From: Role of diffusion-weighted MRI in characterization of mediastinal masses
Case of non-Hodgkin lymphoma. A 14-year-old male patient presenting with fatigue and loss of weight. MRI chest (a) axial T2WI, (b) axial DWI, (c) ADC map showing anterior mediastinal prevascular, right and left paratracheal amalgamated lymph nodes eliciting intermediate signal on T2 WI, patchy high signal on DWI, and low signal on ADC map (restricted diffusion). The mean ADC value was about 0.6 × 10−3 mm2/s
