To evaluate the splenic stiffness of healthy adult cats using acoustic radiation force impulse elastography to determine the quality (greyscale images and tissue deformity) and quantity (shear velocity) standards.
Fifteen healthy, adult shorthair cats were selected. The echotexture, echogenicity, size and edges of the spleen were assessed via mode-B ultrasound. Using qualitative elastography, specific portions of the spleen were evaluated according to homogeneity, presence of deformities and white and dark regions. The shear velocities in different portions of the spleen were quantitatively evaluated.
The echotexture, echogenicity, size and edges of the spleen were normal on B-mode ultrasound in all cats. On qualitative elastography, the evaluated splenic portions were not deformable, and the images presented as homogeneous dark areas. On quantitative elastography, the mean shear velocity values were 1 · 98 m/s for the head portion, 1 · 77 m/s for the body portion and 2 · 03 m/s for the tail portion. These were not significantly different.
Quantitative and qualitative acoustic radiation force impulse elastography of the spleen in healthy adult cats was easily implemented and this study may provide baseline data for this organ to allow the future use of this technique in evaluating cats with splenic disease.
使用声辐射力脉冲弹性成像技术评估健康成年猫的脾脏硬度，以确定质量（灰度图像和组织变形）和数量（剪切波速度）标准。
选取15只健康成年短毛猫。通过B型超声评估脾脏的回声纹理、回声强度、大小和边缘。使用定性弹性成像，根据均匀性、是否存在变形以及白色和黑色区域对脾脏的特定部位进行评估。对脾脏不同部位的剪切波速度进行定量评估。
所有猫的脾脏在B型超声下回声纹理、回声强度、大小和边缘均正常。在定性弹性成像中，评估的脾脏部位不可变形，图像呈现为均匀的暗区。在定量弹性成像中，头部平均剪切波速度值为1.98米/秒，体部为1.77米/秒，尾部为2.03米/秒。这些值无显著差异。
健康成年猫脾脏的定量和定性声辐射力脉冲弹性成像易于实施，本研究可为该器官提供基线数据，以便未来使用该技术评估患有脾脏疾病的猫。
