This paper describes the ultrasonographic appearance, location and size of the spleen in 50 healthy commercial milk cows destined for slaughter. The intercostal spaces of the left thoracic wall were scanned with a 3.5 MHz linear transducer. In each intercostal space, the appearance of the splenic parenchyma, the dorsal and ventral margins and the distance between them, and the diameter of the splenic vessels were recorded. The spleen was seen in intercostal spaces 7-12. It was 2.0-5.0 cm thick, and tapered ventrally. The splenic capsule appeared as an echogenic line. The splenic parenchyma consisted of numerous small regularly spaced echoes, and vessels within the parenchyma appeared as anechoic round to oval or elongated images. The long axis was oblique, running caudodorsal to cranioventral. The distance from the dorsal margin of the spleen to the midline of the back was greatest in the 7th intercostal space (60.9+/-6.81) and smallest in the 12th intercostal space (12.7+/-2.85 cm). The extent of the spleen was greatest in the 8th intercostal space (24.9+/-10.77 cm) and smallest in the 12th intercostal space (9.5+/-5.38 cm). The mean diameter of the splenic vessels ranged from 0.66+/-0.28 to 0.90+/-0.65 cm, depending on the intercostal space scanned. Ultrasonography of the spleen in healthy cows provides information that can be used as a reference when examining cattle with suspected splenic disease.
本文描述了50头待屠宰的健康商品奶牛脾脏的超声图像、位置和大小。使用3.5MHz线性探头对左胸壁的肋间间隙进行扫描。记录每个肋间间隙中脾实质的外观、背侧和腹侧边缘及其间距，以及脾血管的直径。脾脏见于第7至12肋间间隙。其厚度为2.0 - 5.0厘米，腹侧逐渐变细。脾包膜表现为一条强回声线。脾实质由许多规则排列的小回声组成，实质内的血管表现为无回声的圆形、椭圆形或细长形图像。长轴倾斜，从尾背向颅腹走行。脾脏背侧边缘到背部中线的距离在第7肋间间隙最大（60.9±6.81），在第12肋间间隙最小（12.7±2.85厘米）。脾脏范围在第8肋间间隙最大（24.9±10.77厘米），在第12肋间间隙最小（9.5±5.38厘米）。根据扫描的肋间间隙不同，脾血管的平均直径范围为0.66±0.28至0.90±0.65厘米。健康奶牛脾脏的超声检查提供的信息可作为检查疑似脾脏疾病牛时的参考。
