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开展合作研究。 1．关于奶牛妊娠早期直肠扫描诊断、妊娠胎囊图像与子宫粘液类似图像的鉴别诊断。发情周期中的液体起着重要作用，胎儿在 Al 后 29 天首次可见。22 至 29 天内，基于 FS 图像的妊娠诊断准确度为 95%。 Al.2后24天，在不同条件下牛肝脏的弥漫性变化中，发现随着肝脏回声的降低，肝脏边缘的水样变性和/或脂肪变钝的程度增加。肝内血管扩张和狭窄可能作为标准出现。3. 根据成年奶牛的正常 USG 图像，肝和门静脉扩张以及肝部回声增强的图像… 更多 enchyma可以作为充血性肝硬化的诊断指标，采用直肠扫描即可简单诊断犊牛先天性心脏病。牛的严重外伤性心包炎中，室间隔缺损和主动脉瓣畸形联合出现的情况较其他缺损更容易出现病变心包图像、心包扩张等。心包囊、纤维蛋白的漂浮和振荡运动可作为诊断指标。5.通过水浴法制作的动物肿瘤和3种模型之间的声束衰减的比较可以将肿瘤分为三类。体内恶性肿瘤的组织学图像显示混合回声模式，而良性肿瘤的组织学图像显示均匀的回声模式。6．妊娠22天后获得胎囊图像，诊断准确性为100%。在比格犬中，妊娠22天后也观察到胎儿囊图像，诊断准确性为100%。7.在狗和猫的轻度肾积水病例中，出现线性强回声图像。在严重的情况下，观察到与扩张的肾实质和血管结缔组织之间的间隙有关的液体回声图像。获得的骨盆较少。
