[In vivo location of the cortical language areas (correlation between anatomy, x-ray computed tomography and magnetic resonance imaging)].

Cortical language areas were identified by CT scan or NMR imaging, using planes of horizontal sections parallel to the orbitomeatal plane and therefore indirectly to the bicommissural plane. Sections 45 and 50 mm above the bicommissural plane pass electively through temporal structures i.e. the posterior part of T1 and T2, while sections at 60 and 70 mm pass through the angular gyrus and supramarginal gyrus.
