Abstract

Aim: Main purpose of the study was to evaluate ratio of computed radiographic protruded liver length (RLLP) to radiographic liver length (RLL) for setting up a quantitative index in clinically healthy dogs.

Materials and Methods: A total 104 dogs were examined through computed radiography. One year and above aged dogs of 10 breeds of different body weights were included in the study. Computed radiography was done for right lateral (RL) views in all dogs. The ratio was evaluated according to age, sex, body weight, breed and neutering status.

Results: Breeds-wise measurements of ratio of radiographic protruded liver length (RLLP) to radiographic liver length (RLL) were 0.02±0.01, 0.01±0.01, 0.02±0.01, 0.02±0.01, 0.02±0.01, 0.14±0.01, 0.10±0.03, 0.05±0.04, 0.11±0.01, and 0.10±0.01 as mean±S.E. in groups of GSD, BSD, Husky, Doberman, GR, Lab, IM, Pom, Pug, and Beagle respectively. Age-wise measurements of ratio of radiographic protruded liver length (RLLP) to the radiographic liver length (RLL) were 0.05±0.01, 0.11±0.02, 0.09±0.02 and 0.09±0.04 in 1-3 year, 3.1-6 year, 6.1-9 year and 9.1-12 year of age groups, respectively. Body weight-wise measurements of the ratio of radiographic protruded liver length (RLLP) to radiographic liver length (RLL) were 0.09±0.01, 0.04±0.01 and 0.14±0.05 in groups of 10-20 Kg, 21-30 Kg and 31-40 Kg respectively. Sex-wise measurements of the ratio of RLLP/RLL were measured in male 0.08±0.01 and female 0.07±0.01. Neutering status wise measurements of the ratio of RLLP/RLL were 0.06±0.01 in intact dogs and 0.10±0.02 in neutered (spayed/castrated) dogs.
