Objective: Curved planar reformation (CPR) is a new technique for visualizing three dimensional MR imaging. This technique helps in identifying anatomic structures by demonstrating the whole gyral and sulcal pattern of the brain at once. The aim of the present study was to evaluate the usefulness of CPR in identification of the central sulcus on affected hemispheres.

Methods: Functional magnetic resonance imaging (fMRI) was studied in 34 patients with intracranial lesion adjacent to the central sulcus. fMRI was performed with a 3.0 Tesla scanner during repetitive opening and closing of each hand. The central sulcus was defined as the nearest sulcus to the highest activation spots. Three-dimensional MR imaging data sets were processed using a CPR method to create brain surface reformatted images. We accepted five anatomical features widely spreading in clinical usage to identify the central sulcus: 1, termination of the superior frontal sulcus in the precentral sulcus; 2, intraparietal sulcus joins the postcentral sulcus; 3, precentral gyrus is thicker than postcentral gyrus; 4, the inverted omega-shape of the precentral gyrus and 5, the central sulcus is isolated sulcus.

Results: The central sulci identified by fMRI coincided with those identified by CPR in 34 hemispheres of patients. Applicability of each five sign is 61.8, 73.5, 58.8, 50.0 and 67.6%, respectively.

Conclusions: CPR method will be recommended for identification of the central sulcus.
