概括

磁共振弹性图 (MRE) 在检测前列腺癌 (PCa) 方面表现有前途. 这种成像技术可以将PCa与正常组织和良性疾病区分开来,从而有可能改善诊断.

科学领域:

医疗成像医学成像
在瘤学瘤学.
生物物理学的生物物理.

背景情况:

前列腺癌 (PCa) 诊断依赖于各种成像和活检方法.
多参数MRI (mpMRI) 是一个关键的工具,但需要进一步的非侵入性表征.
磁共振弹性成像 (MRE) 测量组织刚度,提供了一个潜在的新诊断参数.

研究的目的:

研究使用盆腔MRE用于检测和分类前列腺癌 (PCa) 的可行性.
为了比较PCa,良性前列腺增生 (BPH) 和正常前列腺组织的刚度值.
评估MRE在区分PCa与其他前列腺疾病方面的诊断性能.

主要方法:

在手术切除之前,75名疑似PCa的患者接受了mpMRI,包括MRE.
硬度值测量在癌症,BPH和正常膜的区域.
组织病理学作为参考标准;统计分析包括t测试和ROC曲线分析.

主要成果:

与正常腹膜 (3.6 ± 0.3 kPa,p < 0.0001) 和BPH (4.5 ± 1.4 kPa,p = 0.0454) 相比,PCa组织表现出明显更高的硬度 (4.9 ± 1.1 kPa).
在区分PCa与正常组织方面,MRE获得了87%的准确性,73%的灵敏度和99%的特异性 (AUC在4.2kPa的截止值为0.839).
刚度值与ISUP等级的增加相关,这表明与癌症攻击性有联系.

结论:

盆腔MRE是一种可行的检测和分类前列腺癌的技术.
MRE可以区分PCa与正常的前列腺组织和BPH.
MRE可以作为传统的mpMRI的宝贵补充,用于增强PCa诊断.

关键词:

Magnetic Resonance Imaging

Magnetic Resonance Imaging

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...

Proteomics

Proteomics

A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term...
