Visible on 95 % of [[CT]]s and 91 % of MRIs Practical point On axial images it appears as a short sulcus, reaching the apex but not extending laterally. It is an excellent landmark to help confirm the location of the [[central sulcus]], which is located one sulcus anterior to the [[marginal sulcus]], on the other side of the [[precentral gyrus]]. Located slightly posterior to the widest [[biparietal diameter]]. pars_marginalis.txt Last modified: 2025/06/26 14:20by administrador
