项目摘要
PROJECT SUMMARY/ABSTRACT
The X-ray unit is a fundamental tool in the clinical setting providing high diagnostic yield for low cost. Its use is
over-looked in preclinical studies due to the resolution necessary to visualize anatomical structures relevant to
DXA
the smaller research species. We requests funds for the purchase of a Faxitron® Ultrafocus to serve as an
initial low cost surveillance tool for monitoring the general health status/phenotyping of our rodent species prior
to considering more costly and time intensive 3-D imaging.
The Faxitron® UltrafocusDXA is a self-contained, cabinet style X-ray system capable of resolving both
anatomical/physiological features down to 8 microns. The unit is designed to provide small animal in vivo
imaging with inclusion of an anesthesia port and viewing window for monitoring depth of anesthesia. The fine
detailed images provide qualitative and quantitative information over a diverse range of experimental models
including visualization of tumors with bony metastases, quantifying elongation of bone and healing of bone
fractures, and visualization of soft tissue structures (vasculature, organs) via the aide of contrast media.
Monitoring of disease progression or therapeutic effectiveness is readily achievable at the whole animal level.
The Faxitron is also outfitted with a Dual-energy X-ray Absorptiometry (DXA) component allowing quantitative
measurements of bone mass, bone mineral density, % fat and % lean tissue maps. The DXA scanning
component provides quantitative measurements of bone loss or gain, and this feature along with the high
resolution images allows phenotyping of genetically altered mice. Resulting images are suitable for
publication and are of a greater quality than that produced by the Piximus unit (current gold standard).
As a testament to its versatility, minor users include the UW Department of Agronomy for seed analysis,
Wisconsin Veterinary Diagnostic Lab for necropsy needs (imaging of zoo and wildlife species) and the UW
Comparative Orthopaedic Research Lab for histological purposes.
Overall, this unit will serve as an excellent cost-effective, user-friendly resource enabling investigators in
multiple departments and disciplines to acquire initial surveillance images of animal and plant specimens, and
to examine the complexity of various structures in a convenient, accessible format. Such technology will
accelerate, enhance, and expand their current research and level of inquiry. It will provide new opportunities for
collaboration and external research funding.
项目摘要/摘要
X光设备是临床环境中的基本工具,以低成本提供高诊断率。它的用法是
由于可视化相关解剖结构所必需的分辨率,在临床前研究中被忽视
DXA
较小的研究物种。我们请求资金购买Faxitron®UltraFocus作为
初步的低成本监测工具,用于监测我们啮齿动物物种的一般健康状况/表型
考虑更昂贵、更耗时的3-D成像。
Faxitron®UltraFocus DXA是一款独立的柜式X射线系统,能够解决
解剖/生理特征小至8微米。该装置旨在为活体小动物提供
包括麻醉口和用于监测麻醉深度的观察窗的成像。罚款
详细的图像提供了各种实验模型的定性和定量信息
包括肿瘤骨转移的可视化,骨的伸长和骨愈合的量化
骨折,以及通过造影剂辅助的软组织结构(血管系统、器官)的可视化。
在整个动物水平上很容易实现对疾病进展或治疗效果的监测。
Faxitron还配备了双能X射线吸收测量仪(DXA)组件,允许
测量骨量、骨密度、脂肪百分比和瘦肉率组织图。DXA扫描
组件提供骨丢失或骨获得的定量测量,这一功能与高
分辨率图像可以对基因改变的小鼠进行表型鉴定。生成的图像适用于
这些出版物的质量比Piximus单位(目前的黄金标准)更高。
作为其多功能性的证明,较小的用户包括华盛顿大学用于种子分析的农艺部,
威斯康星州尸检需求兽医诊断实验室(动物园和野生动物物种成像)和威斯康星州
用于组织学目的的比较骨科研究实验室。
总体而言,该股将成为一个极具成本效益、方便使用的资源,使调查员能够在
多个部门和专业获取动物和植物标本的初步监测图像,以及
以一种方便、可访问的格式检查各种结构的复杂性。这样的技术将会
加快、提高和扩大他们目前的研究和调查水平。它将为以下方面提供新的机遇
合作和外部研究资金。
