Project Summary/Abstract Minnesota HealthSolutions (MHS) proposes a Phase II project to develop and validate a software product capable of automatically detecting and staging pulmonary embolisms (PEs) using clinically routine pulmonary CT angiograms (CTAs). The proposed system will combine state-of-the-art machine learning methods and the clinical expertise at Duke University into a system that integrates seamlessly into the Radiology workflow and standard patient care path to improve the treatment decisions of physicians in the emergency department. Pulmonary embolism is the third most common cause of death in hospital patients with an estimated incidence of 1 per 1,000 patients. CTAs are routinely used to detect PE today; however, there is significant variability in the detection rate among radiologists using CTA. Furthermore, despite the strong evidence that the RV/LV ratio is an important clinical biomarker it is rarely measured quantitatively in practice. A successful completion of this project would provide a workflow-integrated tool capable of faster PE detection and more accurate staging of right heart strain to guide the physician’s treatment decision.

项目总结/摘要 Minnesota HealthSolutions（MHS）提出了一个开发和验证软件产品的第二阶段项目 能够使用临床常规肺动脉栓塞（PE）自动检测和分期 CT血管造影（CTA）。拟议的系统将结合联合收割机最先进的机器学习方法和 将杜克大学的临床专业知识整合到一个系统中， 标准的病人护理路径，以改善急诊科医生的治疗决策。 肺栓塞是住院患者死亡的第三大常见原因， 发病率为1/1000例。CTA今天被常规用于检测PE;然而， 使用CTA的放射科医师之间检出率的变异性。此外，尽管有强有力的证据表明， RV/LV比值是重要临床生物标志物，但在实践中很少定量测量。一个成功 该项目的完成将提供一个工作流程集成工具，能够更快地检测PE， 准确的右心劳损分期，以指导医生的治疗决策。
