Representative images showing the measurement of regional brain sizes.
A coronal section at the level of the cochlea and basilar truncus apparent (A) and the lateral ventricular atrium (B) are measured for the bi-parietal width (BPW) and interhemispheric distance (IHD) on A and for the atrial width of each lateral ventricle (AWLV) and trans-cerebellar diameter (TCD) on B. A midline sagittal section (C) was used for the measurement of callosal thickness at the genu (gCC), mid-portion of the body (bCC) and splenium (sCC) and antero-posterior cerebellar diameter (APCD). A sagittal section, with which a plain from the thalamus to the occipital horn is maximally visible (D), was used for the measurement of the thalamo-occipital distance of the lateral ventricle (TOD). An axial section, with which the caudate, lentiform nuclei and the thalamus are observed with their maximal sizes (E), was used for the measurement of the fronto-occipital diameter (FOD) and the deep-grey-matter area (DGMA).
