Morphometric Analysis of Ventricular Indexes and Intracranial Cerebrospinal Fluid Spaces in the Brain Using Magnetic Resonance Imaging Healthy in Van Cats
(Bmc, 2025) Delibas, Veysel; Goya, Cemil
BackgroundVentricular 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.ResultsFor 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): & Idot;ntracranial 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, V1: 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 degrees +/- 4.42 degrees.ConclusionsThe 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.
Brain Asymmetry and Morphometric Measurements of the Encephalon in Van Cats by Magnetic Resonance Imaging
(Univ Tripoli, Fac Vet Med, 2025) Delibas, Veysel; Soyguder, Zafer; Goya, Cemil
Background: Brain asymmetry is defined as neuroanatomical or functional differences between the brain's left and right hemispheres. These differences can be explained as morphometric changes in regional brain size or functional changes resulting from neuronal density.
Aim: This study aimed to use magnetic resonance imaging (MRI) to visualize the brain tissue of Van cats, obtain anatomical morphometric measurements, and examine brain asymmetry.
Method: A total of 20 healthy adult Van cats, including 10 females and 10 males, who had not undergone any surgical procedures, were included in the study. The animals were anesthetized using a combination of ketamine and xylazine. Midsagittal and dorsal cross-sectional images were acquired using an MRI scanner. Images were transferred to a workstation and processed in DICOM format. Morphometric measurements were obtained using the Enlil PACS radiological image processing and archiving program.
Results: Statistical analysis of the morphometric measurements revealed that, with the exception of encephalon height, most parameters were significantly higher in male Van cats (P < 0.05). Additionally, the study assessed brain asymmetry in Van cats and found a general asymmetry favoring the right hemisphere (hemispherium cerebri dexter). In female Van cats, regional brain asymmetry was observed specifically toward the right frontal cortex (cortex frontalis dexter) (P < 0.05).
Conclusion: This study provides a valuable tool for defining some morphometric measurements of the sagittal and dorsal planes of the brain of Van cats and demonstrating brain asymmetry in cats.
