项目摘要
Project Summary
Prostate cancer is one of the most commonly occurring forms of cancer, accounting for 21% of all cancer in men.
The Prostate Imaging Reporting and Data System (PI-RADS) aims to standardize reporting of prostate cancer
using multi-parametric magnetic resonance imaging (mpMRI). However, the in-depth analysis, as demanded
by PI-RADS, remains challenging due to the complexity and heterogeneity of the disease, and it is a clinically
burdensome task subject to both significant intra- and inter-reader variability. Auxiliary tools based on machine
learning methods such as deep learning can reduce diagnostic variability and increase workload efficiency by
automatically performing tasks and presenting results to a radiologist for the purpose of decision support. In
particular, automated identification and classification of lesion candidates using imaging data can be performed
with respect to PI-RADS scoring. In Phase I of this project, we developed two automated methods to reduce the
intra- and inter-observer variability while interpreting mpMRI images using the PI-RADS protocol: (i) a method
to co-register mpMRI data, and (ii) a method to geometrically segment the prostate gland into the PI-RADS
protocol sector map. The overarching goal of this Phase II project is to develop machine learning algorithms that
incorporate both co-registered multi-modal imaging biomarkers and PI-RADS sector map information into an
automated clinical diagnostic aid. The innovation in this project lies in the use of deep learning to automatically
predict PI-RADS classification. This project is significant in that it has the potential to improve clinical efficiency
and reduce diagnostic variation in prostate cancer diagnosis. In Aim 1 of this project, we will develop a deep
learning approach to localize and classify lesions in mpMRI. In Aim 2, we will integrate this diagnostic tool into the
ProFuseCAD system and perform rigorous multi-site validation to quantify PI-RADS classification performance.
Both aims will utilize a database of over 1,000 existing mpMRI images from multiple clinical sites to develop and
validate the algorithms. Ultimately, enhancements from this project will create a novel feature for Eigen's (the
applicant company's) FDA 510(k)-cleared imaging product, ProFuseCAD, in order to improve the diagnosis and
reporting of prostate cancer.
项目摘要
前列腺癌是最常见的癌症形式之一,占男性所有癌症的21%。
前列腺成像报告和数据系统(PI-RADS)旨在标准化前列腺癌的报告
使用多参数磁共振成像(MPMRI)。但是,按要求的深入分析
由于疾病的复杂性和异质性,pi-rads仍然受到挑战,这是临床上的
负担重大的任务均受到显着的内部和读取器变异性的约束。基于机器的辅助工具
诸如深度学习之类的学习方法可以减少诊断可变性,并通过
自动执行任务并将结果呈现给无线电主义者,以实现决策支持的目的。在
可以使用成像数据对病变候选物进行特殊的自动识别和分类
关于Pi-Rads得分。在该项目的第一阶段,我们开发了两种自动化方法来减少
使用PI-RADS协议解释MPMRI图像时观察者内和观察者的可变性:(i)一种方法
共同注册mPMRI数据,(ii)几何将前列腺分割到Pi-Rads中的方法
协议扇区图。该第二阶段项目的总体目标是开发机器学习算法
将共同注册的多模式成像生物标志物和Pi-Rads扇区映射信息纳入一个
自动临床诊断辅助工具。该项目的创新在于使用深度学习自动
预测Pi-Rads分类。该项目显着,因为它有可能提高临床效率
并减少前列腺癌诊断的诊断变化。在该项目的目标1中,我们将发展一个深刻的
在mpMRI中局部和分类病变的学习方法。在AIM 2中,我们将将此诊断工具集成到
PROFUSECAD系统并执行严格的多站点验证,以量化Pi-Rads分类性能。
这两个目标都将利用来自多个临床站点的1,000多个现有MPMRI图像的数据库来开发和
验证算法。最终,该项目的增强功能将为eigen创造一个新颖的功能(
