概括
这项研究建立了特定于年龄和性别的MRI规范,用于大脑小血管疾病 (SVD) 的表现. 这些发现有助于临床医生更好地评估个体SVD负担并检测异常.
科学领域:
- 神经成像是一种神经成像.
- 放射学 放射学是一门学科.
- 老年学是一门学科.
背景情况:
- 脑小血管疾病 (SVD) 在MRI上包括白质超强度,缺口,微型血液和缩.
- 虽然有些SVD是正常的衰老,但高负担与认知衰退和血管事件相关.
- 从临床上讲,区分正常和异常的SVD负担是具有挑战性的.
研究的目的:
- 创建MRI SVD表现的特定年龄和性别规范数据.
- 帮助临床评估个体SVD负担.
- 为了支持检测异常的SVD模式.
主要方法:
- 利用了来自5402名参与者的11465张MRI扫描 (罗德丹研究).
- 开发了白质超强度和大脑辅酶体部分的百分位曲线.
- 创建了缺口和微型血液流行率的概率曲线,并在45-100岁之间计数,按性别分层.
主要成果:
- 随着年龄的增长,SVD负担加快,白质超强度分数每10年翻一番.
- 在男性 (从45岁开始) 中,大脑辅酶分数比女性 (从60岁开始) 早期和更显著地下降.
- 女性的白质超强度分数较高;男性的缺口和微型血液较多.
结论:
- 为SVD表现提供了全面的规范性MRI数据.
- 数据呈现为年龄和性别分层百分位和概率曲线.
- 有助于量化个体SVD负担和识别异常.

4.9K
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...

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...
