项目摘要

Title: Improving diagnostic US specificity on breast biopsies using US-guided Diffuse Optical Tomography Abstract In current clinical practice, while the characteristics of malignant and benign breast lesions are well established by conventional imaging techniques, the overlapping appearances of malignant and benign lesions have prompted radiologists to recommend biopsy for most low and moderate risk breast lesions. As a result, in the United States, approximately one million image-guided breast biopsies are performed each year, with the majority of the lesions yielding benign results. Many attempts to improve this situation have not been successful. This application will explore the potential impact of Ultrasound (US)-guided diffuse optical tomography (DOT) as an adjunct to US in a diagnostic setting, with the goal of reducing benign biopsies without compromising cancer detection sensitivity. US-guided DOT provides hemoglobin concentration values and distributions which in turn map out lesion vascularity or angiogenesis. Recently, we retrospectively evaluated 288 patients to assess the potential clinical impact of our technique in characterizing low and moderate risk breast lesions, which might not need to be biopsied if the US-guided DOT technology were used in the biopsy decision making process. In this patient cohort, the total hemoglobin level combined with two radiologists’ diagnosis achieved high sensitivity of 96.6-100% on cancer detection and negative predictive value of 99-100%. Using a conservative threshold for the total hemoglobin (tHb) data to differentiate lesions based on the amount of vascularity, we found the number of lesions that would be referred to biopsy decreased by approximately 45% on average, while maintaining high detection sensitivity. Our hypotheses are: 1) The first hypothesis is that the measured tHb values and distribution can be potentially used as an adjunct for radiologists to reduce unnecessary biopsies in low risk patients with benign pathological results; and 2) The second hypothesis is that while reducing unnecessary benign biopsies, the addition of adjunct information from US-guided DOT still maintains a high sensitivity of capturing nearly all malignant tumors. In this application, we propose three aims: 1) Optimization and validation of a new non-iterative imaging reconstruction algorithm and new statistical methods for automated data processing, robust data selection, with the goal of near real-time imaging for onsite diagnosis by physicians. This is a significant step forward to bring this technology into clinics; 2) To prospectively assess the impact of adjunctive US-guided DOT to conventional breast imaging on accurate breast cancer diagnosis and reduction of benign biopsy. Approximate 300 patients will be recruited at the Radiology Department of Washington University to validate the early retrospective results; and 3) Perform statistical analysis to validate the reduction of benign biopsy while maintaining high sensitivity. The successful completion of the project will help initiate a paradigm shift in how we manage low risk benign lesions without compromising cancer detection sensitivity in current clinical practice and will reduce health care cost without compromising patient care.
标题:使用超声引导的漫反射光学技术提高乳腺活检的超声诊断特异性 层析成像 摘要 在目前的临床实践中,虽然恶性和良性乳腺病变的特征已经确立 通过传统的成像技术,恶性和良性病变的重叠表现 促使放射科医生建议对大多数低风险和中等风险的乳腺病变进行活检。因此,在 在美国,每年大约有100万例影像引导下的乳腺活检, 大多数病变产生良性结果。改善这种情况的许多尝试都没有成功。 这项应用将探索超声(US)引导的漫反射光学断层扫描(DOT)的潜在影响 美国在诊断环境中的一个附属机构,目标是减少良性活检而不损害癌症 检测灵敏度。US引导的DOT提供了血红蛋白浓度值和分布,进而 标明病变血管或血管生成情况。最近,我们对288名患者进行了回顾性评估,以评估 我们的技术在表征低风险和中等风险乳腺病变方面的潜在临床影响,这可能不是 如果在活检决策过程中使用了美国引导的DOT技术,则需要进行活检。在这 患者队列中,总血红蛋白水平结合两位放射科医生的诊断获得了较高的敏感性。 癌检出96.6%~100%,阴性预测值99%~100%。使用保守的阈值 在总血红蛋白(THb)数据的基础上区分病变的血管数量,我们发现 在保持较高水平的同时,将转诊至活组织检查的病变平均减少约45% 检测灵敏度。 我们的假设是:1)第一个假设是测量的THB值和分布可能是潜在的 作为放射科医生的辅助工具,用于减少良性病变低风险患者不必要的活检 结果;和2)第二个假设是,在减少不必要的良性活检的同时,添加辅助性 来自美国引导的DOT的信息仍然保持着几乎所有恶性肿瘤的高度敏感性。在……里面 在这一应用中,我们提出了三个目标:1)优化和验证新的非迭代成像 重建算法和新的统计方法,用于自动数据处理、稳健的数据选择,以及 医生现场诊断的近实时成像的目标。这是向前迈出的重要一步 这项技术进入临床;2)前瞻性地评估美国引导的辅助DOT对常规DOT的影响 乳腺影像对乳腺癌的准确诊断和良性活检的减少。大约300名患者 将在华盛顿大学放射科招聘,以验证早期的回顾结果; 3)在保持较高灵敏度的同时,进行统计分析,以验证良性活检的减少。 该项目的成功完成将有助于启动我们管理低风险良性的方式的范式转变 在目前的临床实践中,在不影响癌症检测灵敏度的情况下损害,并将减少医疗保健 在不影响患者护理的情况下降低成本。
