From: Functional imaging with diffusion-weighted MRI for lung biopsy planning: initial experience
A 62-year-old man presenting with a heterogeneous mass in the superior lobe of the right lung. (A): Fusion of axial fat-saturated T1-weighted and diffusion-weighted sequences. Magnetic resonance imaging (MRI) demonstrated that only the anteromedial portion (arrow) of the mass showed high signal intensity on the diffusion-weighted MRI sequence, suggesting that the rest of the mass may be composed of atelectasis, consolidation, or necrosis. (B) Computed tomography (CT)-guided biopsy was directed to this area, and histopathological examination yielded a diagnosis of lung adenocarcinoma.
