Planum temporale volumes were determined for 42 control children (ages 4.2-15.7 years) using magnetic resonance imaging. The mean left planum temporale volume was 2729 mm3 (SD = 567) and the mean right planum temporale volume was 2758 mm3 (SD = 546). No significant hemispheric asymmetry was demonstrated. Analysis of co-variance (ANCOVA) showed that the absolute and proportional planum temporale volumes were not significantly associated with age or gender. We also demonstrated a reproducible method for planum temporale volume measurement by acquiring images in the coronal plane and then visualising the sagittal plane to improve accuracy for the posterior border.
使用磁共振成像确定了42名对照儿童（年龄4.2 - 15.7岁）的颞平面体积。左侧颞平面平均体积为2729立方毫米（标准差 = 567），右侧颞平面平均体积为2758立方毫米（标准差 = 546）。未显示出明显的半球不对称性。协方差分析（ANCOVA）表明，颞平面的绝对体积和比例体积与年龄或性别均无显著相关性。我们还展示了一种可重复的颞平面体积测量方法，即通过在冠状面获取图像，然后观察矢状面以提高后缘的准确性。
