确定最可靠的MRI衍生测量来评估与分娩进展相关的骨盆尺寸.
为了确定特定的骨盆测量参数的预测值,单独和与体重指数 (BMI) 相结合.

主要方法:

一项前性观察性研究,涉及154名怀疑有狭窄骨盆或胎儿过度生长的患者.
在怀孕大约34.7周时使用1.5TMRI系统进行MRI骨盆测量.
测量关键的骨盆尺寸,包括出口直径 (SOD),产科结合体和各种角度;排除胎儿异常和不令人放心的胎儿状态.

主要成果:

在78个分娩试验中,15个导致了因分娩受阻而出现的剖腹产.
交叉出口直径 (SOD) 截止值为10.7厘米,表明曲线下的面积 (AUC) 为0.69,用于预测受阻分娩.
体重指数 (BMI) >22.2 的AUC也为0.69;BMI和SOD组合的特异性提高到90%.

结论:

核磁共振骨盆测量是选择患有阻塞分娩风险较高的患者的一个有价值的工具.
交叉口径 (SOD) 是阻碍分娩的重要预测指标,特别是在BMI较低 (<22.2) 的女性中.

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 IV: Magnetic Resonance Imaging

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,...

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,...
