“…Caudal fossa volume, CC volume, and volume ratio means were significantly different in males and females, being greater in the former. Other authors have reported the difference in the size of the CC between male and female dogs, 21–23 but to the authors' knowledge there are no specific data for the caudal fossa volume and the volume ratio that we describe. Smaller volumes of the posterior fossa and supratentorial cavity were reported in girls than in boys, suggesting that calculating the ratio between the posterior fossa and supratentorial CC volumes may eliminate sex difference in the data 16 .…”

This investigation was initiated to develop a reliable and simple computerized tomography (CT) method for evaluating the morphometry of the cranial cavity (CC) and caudal cranial fossa in the dog. We obtained linear, area, and volume measurements of the entire CC and the caudal fossa compartment in 24 dogs, using transverse and reformatted sagittal and dorsal CT images. The ratios between the CC and the caudal fossa volumes were calculated, as were the ratios between the CC and caudal fossa midsagittal (MS) areas. There were statistically significant correlations between absolute volume data and certain linear measurements, a positive correlation between volume ratio and weight, and significant differences in absolute volume values and volume ratio between males and females. The volume ratio, MS area, and certain linear measurements included in this study can be considered as accurate parameters to evaluate the relative size of the CC to caudal fossa in the dog. Such quantitative measures may be useful in systematically characterizing Chiari-type malformations and other developmental anomalies in the dog.

Rabbits are used in human and veterinary medicine as experimental animals. Most medical instruments are also applied to humans after being tested generally on some animals. 1 Technical achievements and the strict application of accurate anatomical knowledge to surgical and clinical practices have added a new dimension to the diagnosis and the surgical or medical treatments of some diseases. It has been already known that computed tomography (CT) currently plays a dominant role in diagnosis and evaluation of many human diseases and human anatomic structure. Recent papers have also described the use of the CT in veterinary medicine. 2,3 Before any tool can become an effective diagnostic modality, normal species -specific data must be characterized. Publication of clinically relevant CT anatomy is basic to effective utilization of this modality in veterinary medicine. 4 The CT anatomy can be used not only in diagnostic procedures but also in many biometric researches, which constitutes an immense contribution to the evaluation of breeds. 5,6 Previous anatomical descriptions on the rabbit kidneys were rather superficial. 7,8 Moreover, as there is no study on normal CT anatomy of the rabbit, this study

“…Biometrical studies on anatomy using computed tomography make an important contribution to breed identification (Onar et al., 2002; Regedon et al., 1991) in the era of technological advancements in veterinary anatomy (Choudhary et al., 2023). Specialized software is used to construct 3‐dimensional models of the anatomical region.…”

This study aimed to determine the morphometric measurements anatomically and CT images of skulls of healthy male and female rabbits during postnatal development, to analyse the data statistically and to demonstrate the structural changes in bone. A total of 40 rabbits (20 females and 20 males) were divided into four groups including prepubertal period (group I (0–1 month)), period between adolescence and adulthood (group II (3‐5 month)) and later (young adult period as group III (1–3 years) and old adult period as group IV (3–5 years)), with five animals in each group. After the morphometric measurements, the surface area and volume values of the skull were calculated. The skulls were reconstructed using a 3D Slicer (5.0.2), which is used for 3D modelling. The cranial bones in each group were then crushed using a grinder so that the powdered samples were obtained for XRF (X‐ray fluorescence technique). The p‐value was statistically highly significant between group and gender (p < 0.001). In morphometric measurements, males were generally higher than females. Only PL, GBOC and GNB measurements were higher in females. The p‐value between groups (in all measurements), between genders (in TL, GLN, FL, VL, OZB and GBN parameters) and between groups and genders (in TL, DL and VL parameters) was statistically highly significant (p < 0.001). The p‐value between the groups, p‐value between sexes and p‐value between group and sex in Si, P, K, Ca, Ni, Zn, Sr, Sr and Ca/P elements were statistically significant (p < 0.001). Consequently, metric, volume and surface area measurements were taken through 3D modelling of skull bone in prepubertal period (group I), period between adolescence and adulthood (group II) and later (young adult period as group III and old adult period as group IV) of rabbits and the change in the mineral structure during postnatal development and effect of sex on this change were investigated. This might be the first study to assess both metric and mineral changes at four age intervals taken during the life span of rabbits.
