The arrow in the axial T2-weighted image (a) shows an area of intermediate to low-signal intensity in the right peripheral zone. This corresponds to mild, restricted diffusion on the echo-planar diffusion-weighted sequence (b), due to the slow speed of blood flow and focal enhancement on DCE imaging (c)Back to article page
