Imaging Studies VII: Vascular Imaging

54
DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

¹H NMR Signal Integration: Overview

1.7K
The intensity of a signal, which can be represented by the area under the peak, depends on the number of protons contributing to that signal. The area under each peak is shown as a vertical line called an integral, with the integral value listed under it, as seen in the proton NMR spectrum of benzyl acetate. Each integral value is divided by the smallest integral value to obtain the ratio of the number of protons producing each signal. The ratio reveals the relative number of protons and not...

Magnetic Resonance Imaging

6.7K
Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

科学领域:

  • 数字病理学
  • 生物医学图像分析
  • 计算机成像

背景情况:

  • 血素和欧 (H&E) 染色是组织学的基石,但提供有限的分子和结构信息.
  • 多模式成像技术可以提供补充数据,有可能改善组织病理学解释.
  • 需要量化方法来客观地比较不同成像模式的信息内容.

研究的目的:

  • 开发和应用一个量化框架来比较H&E,多式成像和组合数据集的信息内容.
  • 评估多式成像中的单个通道的信息获取,包括连贯抗斯托克斯拉曼散射 (CARS) 显微镜的光谱通道.
  • 建立一个可复制的方法来评估数字病理学的成像方法.

主要方法:

  • 使用深度学习和放射学来提取特征.
  • 实施的信息标记包括香农,曲线下的反面积 (1-AUC) 和主要成分分析 (PC95).
  • 使用Python 3.12对H&E,多式成像及其组合的信息内容进行比较.

主要成果:

  • 与单独的H&E或多式成像相比,综合数据集在所有指标中始终显示出更高的信息含量.
  • 例如,使用MobileNetV2功能,组合数据实现了较高的Shannon (0.5740),而不是H&E (0.5310) 和多模式 (0.5385).
  • 综合数据集需要更多的主要组件 (62) 来解释95%的差异,而不是H&E (33) 和多式联运 (47).

结论:

  • 将多式成像与H&E相结合,大大增加了可用于分析的整体信息内容.
  • 这种定量方法为比较和选择数字病理学的最佳成像策略提供了可重现的框架.
  • 多模式成像组合具有在生物医学研究中增强基于图像的分析的巨大潜力.
