A previous report demonstrated a relationship between asymmetries of occipital lobe length measured on magnetic resonance images (MRIs) and the hemisphere verified as dominant for language. This study sought to discern whether asymmetry in occipital pole area is more predictive of the hemisphere dominant for language. Language dominance was identified by the Wada test in 55 patients evaluated for surgical treatment of epilepsy. In a blinded fashion, an examiner measured bilateral occipital pole area on MRIs for each patient. Asymmetry of the occipital pole area on the MRI made at 10 mm above the tentorium was significantly related to language dominance. This two-dimensional analysis was better than previously described linear measurements in discriminating patients with left-hemisphere dominance for language.
先前的一份报告表明，在磁共振成像（MRI）上测量的枕叶长度不对称与经证实为语言优势半球之间存在关联。本研究旨在探讨枕极面积不对称是否更能预测语言优势半球。对55例接受癫痫手术治疗评估的患者进行Wada测试以确定语言优势半球。一名检查人员以盲法在MRI上测量每位患者的双侧枕极面积。在小脑幕上方10毫米处进行的MRI上枕极面积不对称与语言优势显著相关。在区分左半球语言优势患者方面，这种二维分析比先前描述的线性测量更好。
