FIG 2. 70-year-old man with cerebral abscess.
A—C, T2-weighted fast spin-echo (5300/128/2/6) (A) and T1-weighted spin-echo images without (600/14/2/6) (B) and with (C) gadolinium injection show nonspecific "ring-enhancing" mass. Initial radiologic and clinical diagnosis was necrotic glioblastoma.
D—E, Diffusion-weighted ("z" sensitizing direction) multishot echo-planar image (D) (800/123/5/6) and corresponding ADC map (E) show important decrease of diffusion with very low ADC values (.21—.34 x 10-3 mm2/sec) suggesting diagnosis of abscess.
