概括
在MRI上显示的下或下血瘤 (SAH/SCH) 含有小水和出血的羊水,表明产科和新生儿不良后果的风险更高. 这些发现支持怀孕期间SAH/SCH风险分层.
科学领域:
- 产科和妇科 产科和妇科
- 放射学 放射学是一门学科.
- 新生儿医学 新生儿医学
背景情况:
- 腹膜下或腹膜下血瘤 (SAH/SCH) 与不同的妊娠结果有关.
- 在SAH/SCH怀孕中,液和出血羊水对MRI的影响还不清楚.
研究的目的:
- 评估通过胎盘MRI检测到的液和出血羊水在SAH/SCH怀孕风险分层中的重要性.
- 为了将MRI发现与产科和新生儿结局相关联.
主要方法:
- 追溯研究71个单独怀孕的SAH/SCH在MRI (第二或第三季度) 上确定.
- 怀孕是根据MRI发现进行分类的:小卵液和/或出血的羊水.
- 分析的结果包括堕胎,早产 (<34周),新生儿重症监护室 (NICU) 停留时间.
主要成果:
- 与B组 (35.3%) 和C组 (21.4%) 相比,A组 (寡氧水和出血的羊水) 的不良产科结果 (91.7%) 显着更高.

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

459
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
