| Summary: | Ultrasonography, as a non-invasive diagnostic tool, can provide valuable information about the type, nature and duration of certain
musculoskeletal inflammatory processes in animals. The aim of this study was to investigate the correlation between mean echogenicity
(ME) of effusion content and its laboratory finding values. Fifty dairy cows with superficial effusions on their legs were examined in this
study. Ultrasound images were analysed by software processing and ME was determined for every case of effusion. Samples of effusion
contents were collected and sent to the laboratory. Investigated parameters were: Concentration of total proteins, concentration of glucose,
concentration of uric acid, number of leukocytes, percentage of neutrophils, number of erythrocytes, specific weight, viscosity, colour,
clarity and Gram stain. High correlation values between ME and concentration of total proteins (R2=0.7313; P<0.001), concentration of uric
acid (R2=0.7427; P<0.001), percentage of neutrophils (R2=0.6923; P<0.001) and specific weight (R2=0.6963; P<0.001) showed that these
laboratory parameters could have some impact on echogenicity of effusion content.
