摘要
目的应用CT技术对成年猕猴进行断层扫描,建立猕猴腹部及盆腔CT断层扫描图谱。方法选择普通级实验猕猴6只,雌雄各半,年龄5～8岁,取头前尾后仰卧位,采用增强扫描CT技术,对其腹部及盆腔进行断层扫描,采集容积数据及对原始数据重建。通过观察、确认,精选具有解剖意义的扫描图像:腹部7张、盆腔10张(雌雄各5张),对其每个层面的主要脏器进行标注。结果 CT影像能分辨出大部分组织器官的细微变化,较大器官、大血管界面清晰,但较小器官和细小血管、神经、肌肉组织等界面尚不清晰。结论获得了健康成年猕猴腹部及盆腔的影像学图谱,为CT技术在猕猴影像学研究、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。
Objective To obtain X-ray computed tomography（CT） imaging of abdominal and pelvic organs of healthy adult rhesus monkeys.Methods Six conventional laboratory rhesus monkeys,3 male and 3 female,in the age of 5-8 years were included in this study.The monkeys were placed on the CT table-board in supine position and were scanned to get CT images of the abdominal and pelvic organs by enhanced scan techniques.Volumetric data were collected and reconstruction of the original data was conducted.Meaningful anatomical scanning images were observed,identified and selected： 7 images of the abdominal structures and 10 pelvic organs（5 of males and 5 of females）,and each layer of the major visceral organs were labeled.Result On the CT images,the subtle changes of most organs and tissues could be distinguished,and the interface of relatively large organs and blood vessels was clear.But the interface of smaller organs,blood vessels,nerves and muscles,etc.was not distinct.Conclusions CT images of normal abdominal and pelvic structures of healthy adult rhesus monkeys has been obtained in this study.It provides valuable imaging basis for further studies on disease diagnosis and scientific experiments.
