概括

脑静脉形 (CVM),如洞穴形,可以随着时间的推移而变化,并成为症状. 发育性静脉异常 (DVA) 很少引起症状,而毛细血管疏通异常则保持稳定. 黑色素沉积物在CVM中很常见.

科学领域:

神经辐射学神经辐射学
血管神经学血管神经学
医疗成像医学成像

背景情况:

大脑静脉形 (CVMs) 涵盖了大脑中的各种血管异常.
了解它们的发病率,演变和成像特征对于诊断和管理至关重要.

研究的目的:

为了确定CVM的发生率和位置.
为了评估CVM随时间变化的变化.
分析MRI发现,包括不同CVM类型之间的关系,使用磁敏度加权成像 (SWI) 和对比增强MRI.

主要方法:

追溯分析了8,957名来自7,826名患者的SWI和对比度增强的大脑MRI.
详细检查发育性静脉异常 (DVA),包括排水模式,收集静脉,血栓,信号异常和血红蛋白.
洞穴瘤随时间变化的评估 (类型和大小).

主要成果:

在520名患者中发现了643例CVM.
最常见的是DVA (5.26%),其次是洞穴病 (1.28%) 和毛细血管疏通症 (0.62%).
在7.8%的随访病例中,洞穴动物的类型和大小发生了变化,有可能出现症状.

结论:

洞穴瘤可以改变并成为症状,而DVA通常保持无症状.
毛细管疏通症通常是稳定的,通常在额叶中发现的 supratentorial 类型.
在SWI的CVM中经常观察到色素沉积物,通常以结节形式.

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...

Imaging Studies for Cardiovascular System IV: CMRI

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,...
