Multiplanar views of language BOLD activation overlaid on FA-weighted color directional diffusion maps superimposed on postgadolinium 3D magnetization-prepared rapid acquisition of gradient echo high-resolution anatomic images in a patient with a left trigonal intraventricular mass. The BOLD paradigm used is a silent word-generation task. Red-green-blue coding convention is used for DTI display, in which red refers to mediolateral; blue, to superoinferior; and green, to anteroposterior preferential diffusion. Note the activation of both Broca and Wernicke areas in the left hemisphere in this left-language-dominant patient. J.J.
