概括
双参数MRI (bpMRI) 可能会改善前列腺癌检测,而不是捷克共和国的PSA查. 这种方法可以减少必要的活检,同时增加临床显著前列腺癌 (csPC) 的检测.
科学领域:
- 泌尿器科 泌尿器科 泌尿器科 泌尿器科
- 放射学 放射学是一门学科.
- 在瘤学瘤学.
背景情况:
- 捷克共和国的前列腺癌查机会性前列腺特异性抗原 (PSA) 检测率高 (45%).
- 将双参数磁共振成像 (bpMRI) 与PSA查进行比较,对于优化这种人群中PC检测策略至关重要.
研究的目的:
- 为了比较bpMRI和PSA查途径之间的临床显著前列腺癌 (csPC) 检测率.
- 评估bpmri的潜力,以减少PC诊断所需的活检数量.
主要方法:
- 在2022年5月至2023年5月期间,50-69岁的423名男性接受了PSA测试和bpMRI测试.
- 阳性查定义为PSA≥3μg/l或前列腺成像报告和数据系统 (PI-RADS) 得分为4-5.
- 所有阳性病例进行了MRI向和系统活检;csPC定义为国际泌尿病理学会 (ISUP) 级别组≥2.2.
主要成果:
- PSA 途径发现5.9%的男性有可疑结果,而MRI 途径发现3.8%,可能会减少36%的活检.
- 活检证实了1.7%的阳性PSA测试的男性和3.3%的阳性MRI发现的男性的PC.

Magnetic Resonance Imaging
4.8K
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
7.0K
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...
