概括
微血管成像 (MI) 有效地评估新生儿脑微血流,血管指数 (VI) 与妊娠年龄和出生体重有正相关性. 这项技术有助于评估新生儿早期的大脑发育.
科学领域:
- 新生儿神经学
- 医学成像
- 脑血管生理学
背景情况:
- 评估新生儿的大脑微型血流对于理解大脑发育至关重要.
- 微血管成像 (MI) 为此评估提供了一个潜在的非侵入性方法.
研究的目的:
- 评估微血管成像 (MI) 在评估新生儿脑微血流的有效性.
- 确定影响大脑微型血流的因素,并评估MI的可靠性.
主要方法:
- 120名新生儿的回顾性分析 (2022年8月至2023年10月).
- 使用微血管成像 (MI) 计算额叶皮质,白质和基底的血管指数 (VI).

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,...

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...
