Breed traits seem to influence the dimensions of the cerebral ventricles in dogs. The ratios between the ventricles and the brain are crucial diagnostic criteria for suspected canine cognitive dysfunction (CCD). This study aimed to establish linear computed tomography (CT)-scan measurements of the cerebral ventricles in 55 Poodle dogs aged >7 years. To this end, cross-sectional CT images were evaluated. The measurements in the whole sample were: height of the right ventricle, 6.0 ± 1.6 mm; height of the left ventricle, 5.8 ± 1.6 mm; width of the right ventricle, 6.9 ± 1.4 mm; width of the left ventricle, 7.0 ± 1.3 mm; height of the third ventricle, 3.4 ± 0.8 mm; height of the right cerebral hemisphere, 39.5 ± 2.0 mm; and height of the left cerebral hemisphere, 40.2 ± 2.6 mm. The average ventricular measurements were higher in dogs older than 11 years (p < 0.05). However, the average ratio of the ventricle height to the height of the brain did not reveal differences between age groups, sex, or antimeres. In addition, none of the images showed fused lateral ventricles. Thus, these data can assist in interpreting ventricle size in senile Poodle dogs (aged >7 years).
品种特征似乎会影响犬类脑室的大小。脑室与大脑之间的比例是疑似犬类认知功能障碍（CCD）的关键诊断标准。本研究旨在对55只年龄大于7岁的贵宾犬进行脑室的线性计算机断层扫描（CT）测量。为此，对横断面CT图像进行了评估。整个样本的测量结果为：右心室高度6.0±1.6毫米；左心室高度5.8±1.6毫米；右心室宽度6.9±1.4毫米；左心室宽度7.0±1.3毫米；第三脑室高度3.4±0.8毫米；右大脑半球高度39.5±2.0毫米；左大脑半球高度40.2±2.6毫米。11岁以上犬类的平均脑室测量值更高（p<0.05）。然而，脑室高度与大脑高度的平均比值在年龄组、性别或体部之间未显示出差异。此外，所有图像均未显示侧脑室融合。因此，这些数据有助于解释老年贵宾犬（年龄大于7岁）的脑室大小。
