title: ULTRASONOGRAPHIC ELASTOGRAPHY OF THE LIVER, SPLEEN, KIDNEYS, AND PROSTATE IN CLINICALLY NOR-MAL BEAGLE DOGS [corrected].
abstract: Standard ultrasonography is often insensitive for distinguishing normal vs. diseased states for canine abdominal organs. Ultrasonographic elastography is a new technique that is becoming increasingly available and may help to improve sensitivity. This study evaluated the feasibility, repeatability, and reproducibility of strain elastography of the liver, spleen, kidneys, and prostate in healthy dogs and described the elasticity of each organ using strain values and strain ratios. The reproducibility of strain elastography was excellent, and intraobserver repeatability was moderate to excellent. The strain value of each organ was not significantly different among dogs (liver = 143.38 ± 7.41, spleen = 141.04 ± 9.03, left renal cortex = 141.26 ± 7.50, right renal cortex = 145.80 ± 7.79, and prostate = 135.46 ± 5.80), except for the renal medulla (left = 51.19 ± 4.54 and right = 51.93 ± 5.09) (P < 0.05). The strain ratios for the liver, spleen, renal cortex, and prostate were similar with no significant difference (liver = 10.20 ± 1.47, spleen = 8.40 ± 1.53, left renal cortex = 9.62 ± 1.56, right renal cortex = 8.29 ± 1.63, and prostate = 8.20 ± 1.21), except for the renal medulla (left = 3.48 ± 0.68 and right = 2.95 ± 0.63) (P < 0.05). Our results indicated that strain elastography was feasible for estimating tissue stiffness in the canine liver, spleen, kidneys, and prostate. This study provides basic information for strain values and strain ratios for the liver, spleen, kidneys, and prostate in clinically normal dogs.
