Abstract

Aim: Main purpose of the study was to evaluate radiographic liver length to 11^th thoracic vertebral length ratio for setting up a quantitative index in clinically healthy deep chested dogs.

Method and materials:  A total number of 89 deep chested dogs were examined through computed radiography. One year and above aged dogs of 6 deep chested breed of different body weights were included in the study. A complete computed radiography was done for right lateral (RL) and ventro-dorsal (VD) views in all dogs. The ratio was evaluated according to age, sex, body weight, breed and neutering status.

Results: The ratio of radiographic liver length to T11 vertebrae length was recorded as 6.01±0.12, 6.31±0.24, 6.44±0.22 and 5.96±0.18 in 1-3 year, 3-6 year, 6-9 year and 9-12 year of age group, respectively.  Sex wise ratio 6.05±0.14 in male and 6.13±0.13 female group was measured. Body weight wise ratio was 5.38±0.21, 6.13±0.12, 6.47±0.17, 6.39±0.65 in 10-20 Kg, 20-30 Kg, 30-40 Kg and 40-50 Kg of body weight group, respectively. Breed wise ratio was 6.09±0.13, 6.24±0.21, 5.82±0.29, 6.34±0.2, 6.28±0.44 and 5.6±0.38 in German shepherd, Belgium Shepherd, Dobermann, Golden Retriever, Great Dane and Siberian Husky dog breed, respectively. Neuter status wise ratio was 5.8±0.26 and 6.15±0.1 in castrated or spayed and intact group, respectively.

Conclusion: It was concluded that the ratio of radiographic liver length to T 11 vertebrae length has set as a quantitative index of radiographic liver size in deep chested dogs. The normal radiographic liver length was concluded 6.09 times of T11 vertebrae length in deep chested dogs.
