FIG 1. 51-year-old man with cerebral abscess.

A—C, T2-weighted fast spin-echo (5000/128/2/6 [TR/TE/excitations/slice thickness]) (A) and T1-weighted spin-echo without (600/14/2/6) (B) and with (C) gadolinium injection show nonspecific "ring-enhancing" mass.

D—E, Diffusion-weighted ("z" sensitising direction) multishot echo-planar sequence (D) (800/123/5/6) and corresponding ADC map (E) show central hyperintensity on diffusion-weighted image with very low ADC values (.25—.33 x 10^-3 mm²/sec).
