Cortical radioanatomy-practical guide of identification

Cerebral sulci identification process is based on several formal rules : it consists a series of steps allowing the identification of the major sulci. The process may be variable for each of us and we propose to read the imag es in certain order starting with the frontal robe and its superior frontal gyrus than precentral and central gyri followed by the lateral fissure. Th en the insular, lateral parietal and medial hemispheric regions. Finally th e major sulci within the temporal and occipital robes are described in the frontal plane. This presentation indicates the principal rules of cerebral lobes identification, the basis of variability perception and the localizat ion of small lesions allowing an accurate correlation with clinical finding s and a suitable therapeutic procedure.
