项目摘要

Co-operative studies were performed to establish of diagnostic standard and improve the diagnostic accuracy of ultrasonography in veterinary clinic.1. Concerning early pregnancy diagnosis in dairy cattle by rectal scanning, differential diagnosis between fetal sac images indicating pregnancy and simillar images related to uterine mucus fluid during the estrus cycle play an important part. The fetuses were first visible 29 days after Al. Accuracy of pregnancy diagnosis based on development of FS images was 95% between 22 and 24 days after Al.2. In diffuse changes of the bovine liver with various conditions, it was found that as the echogenicity of the liver decreased, the degree of hydropic degeneration and/or fatty change increased. Blunting of the edge of the liver, dilatation and stricture of intrahepatic vessels may be present as a standard.3. Based on normal USG images in adult dairy cattle, images of dilatation of the hepatic and portal vein and increase of echogenicity of the par … More enchyma may be present as a diagnostic indicator for congestive liver chirrhosis. The diagnosis of hydronephrosis and renal cyst was simply made using rectal scan.4. Ultrasonic diagnosis of congenital heart disease in calves was performed by using both linear and sector scanning methods. Detection of ventricular septal defects comprises combined anomaly and anomaly of aortic valves were more easily than other defects. In severe traumatic pericarditis of cattle, images of sickend pericardium, dilatation of pericardial sac, floating and oscillatory motin of fibrin may be present as for diagnostic indicator.5. Comparisons of the sound beam attenuation between removed tumors from animals and 3 types of phantoms were made by water bath method. Tumors may be classified in three categories. Images of histologically malignant tumors in vivo showed mixed echo pattern but in benign tumors uniform echo pattern were obtained.6. By abdominal surface scanning of swine, images of fetal sac were obtained after 22 days gestation with 100% diagnostic accuracy. In beagle dogs, images of fetal sac were also observed after 22 days gestation with 100% accuracy.7. In mild cases of hydronephrosis of dog and cat, images of linear strong echo caused by dilated renal pelvic wall were observed. In severe cases images of fluid filled echo related to fluid which fill the gap between renal parenchyma and vascular connective tissue exposed to dilated renal pelvis were obtained. Less

为建立兽医临床超声诊断标准、提高超声诊断准确性而开展合作研究。 1．对于通过直肠扫描进行的奶牛早期妊娠诊断，表明妊娠的胎囊图像与发情周期期间子宫粘液相关的类似图像之间的鉴别诊断起着重要作用。胎儿在 Al 后 29 天首次可见。 Al.2 后 22 至 24 天之间，基于 FS 图像显影的妊娠诊断准确性为 95%。在不同条件下牛肝脏的弥漫性变化中，发现随着肝脏回声性的降低，水样变性和/或脂肪变的程度增加。肝脏边缘变钝、肝内血管扩张和狭窄可作为标准。3．根据成年奶牛的正常 USG 图像，肝脏和门静脉扩张以及肝部回声增强的图像可能作为充血性肝硬化的诊断指标。直肠扫描简单诊断肾积水、肾囊肿。 4．采用线性扫描和扇形扫描两种方法对犊牛先天性心脏病进行超声诊断。室间隔缺损包括联合异常和主动脉瓣异常比其他缺损更容易检测。牛严重外伤性心包炎可出现病变心包图像、心包囊扩张、纤维蛋白漂浮、振荡等作为诊断指标。 5．采用水浴法比较了动物切除肿瘤与3种体模的声束衰减情况。肿瘤可分为三类。体内恶性肿瘤的组织学图像显示混合回声模式，而良性肿瘤则获得均匀的回声模式。 6．通过对猪的腹部表面扫描，在妊娠 22 天后获得胎囊图像，诊断准确率 100%。在比格犬中，妊娠22天后也观察到胎囊图像，准确率100%。7．在犬、猫的轻度肾积水病例中，可观察到肾盂壁扩张引起的线性强回声图像。在严重的情况下，获得与填充肾实质和暴露于扩张的肾盂的血管结缔组织之间的间隙的液体相关的液体填充回声的图像。较少的
