Abstract: P> Objective To study the morphology, normal values and lateral asymmetry of Chinese calcarine sulcus on MRI. Methods Highresolution and transverse MRI were obtained from 40 female volunteers. Brainvisa software was used to reconstruct the calcarine sulcus and measure its average length, depth and width automatically. Results The posterior branch of calcarine sulcus showed six types in the median sagittal plane: bifurcation(32.50%), single peak(25.00%), flat (16.25%), S-shaped (15.00%), double peak(7.50%) and other shape (3.75%); its location had three types: inferior(72.50%), middle(21.25%)and superior(6.25%). The depth of left calcarine sulcus was (15.24±2.67)mm, and the right one was (16.97±3.25)mm, which revealed great statistical significance (EM>P/EM>0.000 1). The width of left calcarine sulcus was (3.14±0.91)mm, and it was (3.19± 0.83)mm in the right side. The bottom length of calcarine sulcus: the left was (86.47±16.85)mm, the right was (83.62±17.10)mm. The top length of calcarine sulcus: the left was (70.52±12.40)mm, the right was (64.90±15.17)mm. There were not statistical significance in width, bottom length and top length between left and right calcarine sulci. More than half of the end part of calcarine sulci turned to the lateral surface of cerebral hemisphere.T
