实验猕猴肺部CT影像断层初步观察

目的应用CT技术对成年实验猕猴胸部肺窗进行断层扫描观察,探讨CT技术对猕猴肺部疾病的临床诊断意义,建立正常猴肺部CT断层扫描图谱,为CT技术在猕猴解剖学的研究、疾病的临床诊断及科学实验方面的应用,提供影像学的基础资料。方法经过触诊、叩诊、听诊、体温、呼吸率、心率、呼吸运动、血液常规等检查,选择健康猴10只,雌雄各半,年龄分别为5～10岁,进行肺部CT断层扫描检测。试验猴全身麻醉后,置于CT诊断床上,取头前尾后仰卧位进行肺部扫描,获取肺窗扫描图像。对具有解剖意义的扫描图像的每个层面的主要结构（肺叶、气管、动脉血管、静脉血管等）进行标注。结果 （1）获得具有解剖意义的肺窗扫描图像13张。（2）在断层扫描的图像中,肺、气管、较大血管等组织器官界面清晰。肺为左右两侧,左肺分为上叶、中叶、下叶,右肺分为上叶、中叶、下叶、奇叶四部分。不同的断层面分别可见肺部左主支气管、右主支气管、支气管、血管等组织。（3）肺部较小或细小的血管、神经组织界面不清晰。结论 （1）应用CT获得的正常猕猴胸部肺窗断层扫描图像表明,正常健康猴双肺纹理清晰,走行自然,肺野透光度良好,双肺无异常实质病变影像。（2）获得了健康猕猴肺部的CT影像学资料,为猕猴肺部疾病的诊断,提供了一种安全、方便又准确的新依据,建立了成年健康猕猴肺部CT断层解剖研究的背景资料。

Observation of Lung CT Tomography of the Laboratorial Rhesus Monkey

Objective To research the clinical diagnosis of lung disease in rhesus monkey with the observation of lung CT tomography of the adult laboratorial rhesus monkey,to establish the maps of CT tomography of the healthy adult rhesus monkey,to provide the basic image data of CT technology in the applications of anatomy,clinical diagnosis and scientific experiments of rhesus monkey.Methods 5 male and 5 female health adult monkeys aged 5~10 years were selected for this study of lung CT tomography after being checked by palpation,percussion,auscultation and by examination of body temperature,respiratory rate,heart rate,breathing motion and blood parameters.After general anesthesia,the monkeys were placed on the table-board of CT in supine position and were scanned to get the image of lung CT tomography.The main structure of every level in scanned images were labeled,such as lobe,trachea,arteries and veins,etc.Results（1） 13 anatomical images of lung CT tomography are obtained.（2） In the image of CT tomography,lung,trachea,large blood vessels are all in focus.Lungs are composed of the right part and the left part,the left lung is divided into upper lobe,middle lobe and lower lobe.Right lung is divided into upper lobe,middle lobe,lower lobe and azygos lobe.Left main bronchus,right main bronchus,bronchial and vascular are very obvious in different scanned images.（3） Interfaces of small blood vessels,small nerves and muscle tissues are not clearly defined on the CT scanned images.Conclusions（1） The images of lung CT tomography of the healthy adult rhesus monkey show that all the lung lobes are absolutely clear,lung transmittance is good,and there are no any shadows.（2）Obtained the anatomy CT tomography image data of healthy adult rhesus monkey.It can provide a new safe,convenient and accurate basis for diagnosis of monkey lung disease.It also established the background Information data of CT tomography anatomy of the healthy adult rhesus monkey.
