How to Identify Language-related Anatomies on Neuro-imaging

Abstract

  It is not easy for learners to identify exact location of lesions demonstrated on imaging modalities, even though they have enough knowledge of both diseases and neuroanatomy. Here, we described, especially for the beginners, how to identify anatomical locations of them, focusing on relevant gyri and sulci for evaluation of patients with aphasia/language symptoms. In order to read the location accurately, we emphasize that it is of tremendous benefit to use 3D-acquisition protocols for MRI, choose appropriate image plains from the axial, coronal, and sagittal plains, depending on sulci and gyri of interests, and evaluate continuous and multiple images of each plain. Reading process of the central sulcus is usually the first and pivotal step, followed by identification of surrounding structures based on the information of it. We believe that it is of great value not only for better understanding of the patient, but also for contributing to advancements of neuroscience, to perform thorough investigations upon each and every patient, evaluating both neuropsychological findings and the exact anatomical location of lesions.
