PROJECT SUMMARY Thoracic aortic aneurysm (TAA) is a chronic condition that carries the risk of developing life-threatening complications such as aortic dissection (i.e., delamination of the aortic wall) and rupture (i.e., transmural tearing). The primary management objectives for TAA are to identify aortic dilation early and to surgically replace the aorta before it reaches a size that predicts future complications. It is estimated that 3 million patients in the US alone would meet criteria for aortic imaging surveillance based on current guidelines. Improved imaging surveillance strategies are needed to address the health and economic impacts of TAA. However, the reliability of standard aortic diameter measurements from CT images remains low. In this proposal, we will utilize a recently developed image analysis technique, Vascular Deformation Mapping (VDM), to perform semi-automated, three-dimensional assessment of aortic growth in patients with TAA undergoing imaging surveillance. This novel approach utilizes advanced computerized analysis techniques that make full use of the rich, high-resolution, volumetric data generated by modern CT scanners, to generate a more comprehensive and reliable assessment of aortic growth. VDM has the ability to significantly improve the speed and reliability of TAA growth analysis, facilitate the communication of aortic growth assessment between radiologists, care-providers and patients, and generate new biomarkers of disease progression that can be used to improve patient management decisions, and ultimately patient outcomes. In this grant effort, we propose to achieve the goals of this project through our close partnership between University of Michigan (UM) and Imbio, LLC investigators. Thus the Specific Aims of this Fast-Track proposal will develop a commercial VDM software application, including the product testing and data acquisition necessary for a FDA 510(k) application.

项目摘要 胸部主动脉瘤（TAA）是一种慢性病，具有威胁生命的风险 并发症，例如主动脉夹层（即主动脉壁的分层）和破裂（即透壁 撕裂）。 TAA的主要管理目标是尽早识别主动脉膨胀 在预测未来并发症的大小之前，请更换主动脉。据估计有300万 仅美国的患者将符合基于当前准则的主动脉成像监测标准。 需要改进的成像监视策略来解决TAA的健康和经济影响。 但是，CT图像的标准主动脉直径测量值的可靠性仍然很低。 在此提案中，我们将利用最近开发的图像分析技术，血管变形映射 （VDM），对TAA患者的主动脉生长进行半自动化的三维评估 进行成像监视。这种新颖的方法利用了先进的计算机化分析技术 充分利用现代CT扫描仪生成的丰富，高分辨率，体积数据，以生成一个 对主动脉生长的更全面和可靠的评估。 VDM具有显着改善的能力 TAA增长分析的速度和可靠性，促进主动脉生长评估之间的交流 放射科医生，护理人员和患者，并产生可以是疾病进展的新生物标志物 用于改善患者管理决策，并最终导致患者的结果。 在这项赠款工作中，我们建议通过我们之间的密切合作伙伴关系来实现该项目的目标 密歇根大学（UM）和IMBIO，LLC调查人员。因此，该快速提案的具体目的 将开发商业VDM软件应用程序，包括产品测试和数据获取 FDA 510（k）申请所必需的。
