Ventricular indexes are defined as a numerical marker of ventricular dimensions in domestic mammals. The anatomical size of the brain ventricles has been the subject of many studies so far and has been accepted as a potential indicator of many brain disorders in the clinical field. Currently, the number of studies describing the morphometry of the brain ventricular system in cats is limited. Furthermore, no studies have been conducted specifically on indexes characterizing the numerical compatibility of the brain and brain ventricles in cats. The aim of this study was to reveal the morphometric status of intracranial cerebrospinal fluid spaces and ventricular indexes in healthy Van cats by magnetic resonance imaging method.
For this retrospective study, T2-weighted magnetic resonance imaging (MRI) scans were performed at 1.5 T on 20 (10 male and 10 female) Van cats, under general anaesthesia. The animals were at the age of mean 4 (3-5 age). All Van cats were selected from individuals who had not undergone any surgical procedures, were not neutered, and had no visible anomalies. The statistical analysis of first, descriptive statistics such as mean and standard deviation were calculated. In line with the mean results obtained, the difference between sex was examined statistically. 'A Mann-Whitney U test' was applied to detect sex differences in measurement parameters in the study. The results are as follows (mean ± standard deviation): İntracranial cerebrospinal fluid spaces measurements: R-fss: 1.02 ± 0.19 mm, L-fss: 1.03 ± 0.18 mm, A-if: 1.06 ± 0.26 mm, R-sf: 1.38 ± 0.32 mm, L-sf: 1.37 ± 0.27, V: 4.26 ± 0.53 mm. Indexes: Fourth ventricle: 15.95 ± 1.73%, Bifrontal: 17.45 ± 1.78%, Bioccipital: 47.53 ± 9.36%, Evans: 13.76 ± 2.93%, Lateral ventricle: 35.41 ± 2.50%, Callosal angle: 85.06°±4.42°.
The present study provides baseline values of intracranial cerebrospinal fluid spaces and linear indexes of the ventricles in the Van cats. The acquisition of these data contributes to filling the knowledge void on important anatomical and morphological features of the Van cats brain.
心室指数被定义为家畜心室大小的数值标记。迄今为止，脑室的解剖大小一直是许多研究的主题，并已被临床领域公认为许多脑部疾病的潜在指标。目前，描述猫脑室系统形态测量的研究数量有限。此外，尚未有专门针对表征猫脑与脑室数值兼容性的指标进行的研究。本研究的目的是通过磁共振成像方法揭示健康凡湖猫颅内脑脊液间隙和心室指数的形态测量状况。
对于这项回顾性研究，在全身麻醉下，对20只（10只雄性和10只雌性）凡湖猫进行了1.5T的T2加权磁共振成像（MRI）扫描。动物的平均年龄为4岁（3 - 5岁）。所有凡湖猫均选自未接受过任何手术、未绝育且无明显异常的个体。首先进行描述性统计分析，计算均值和标准差等。根据获得的均值结果，对性别差异进行统计学检验。本研究应用“曼 - 惠特尼U检验”来检测测量参数中的性别差异。结果如下（均值±标准差）：颅内脑脊液间隙测量值：右侧额顶间隙（R - fss）：1.02±0.19毫米，左侧额顶间隙（L - fss）：1.03±0.18毫米，前间孔（A - if）：1.06±0.26毫米，右侧侧裂池（R - sf）：1.38±0.32毫米，左侧侧裂池（L - sf）：1.37±0.27毫米，脑室容积（V）：4.26±0.53毫米。指数：第四脑室：15.95±1.73%，双额径：17.45±1.78%，双枕径：47.53±9.36%，埃文斯指数（Evans）：13.76±2.93%，侧脑室：35.41±2.50%，胼胝体角：85.06°±4.42°。
本研究提供了凡湖猫颅内脑脊液间隙和脑室线性指数的基线值。这些数据的获取有助于填补凡湖猫脑部重要解剖和形态特征方面的知识空白。
