概括

本系统性审查确定了关键的成像特征,以区分高等级 (HG) 和低等级 (LG) 脑膜瘤. 这些诊断成像特征提供了一个非侵入性的替代病理分级,当活检是不可行的.

科学领域:

神经学神经学
放射学放射学是一门学科.
在瘤学瘤学.

背景情况:

脑膜瘤是最常见的初级内瘤.
使用世卫组织标准进行病理分类是预测瘤行为的标准.
检查病理学分级的活检可能是具有挑战性的,因为瘤的位置和手术访问.

研究的目的:

系统地审查和评估诊断成像特征,以区分高等级 (HG) 和低等级 (LG) 脑膜瘤.
建立成像作为潜在的替代方案,以病理分类为脑膜瘤.
为了识别特定的MRI和CT特征,表明脑膜瘤等级.

主要方法:

系统审查使用常规MRI或CT的初级研究.
包含评估病理性WHO分级脑膜瘤的研究.
由两名调查人员进行独立选和数据提取.

主要成果:

确定了12个显著的CT和MRI特征来区分HG和LG脑膜瘤.
囊性变化显示高特异性 (93.4%);不规则的瘤-大脑接口具有最高的积极预测值 (65.0%).
质量效应显示出高灵敏度 (81.0%) 和负预测值 (90.7%). 不规则的瘤-大脑接口实现了最高的精度 (79.7%).

结论:

诊断成像特征可以有效地区分高等级和低等级的脑膜瘤.
特定的成像特征,如不规则的瘤-大脑接口和异质增强,是有价值的指标.
本综述强调了非侵入性成像在脑膜瘤分级中的潜力.

Cranial and Spinal Meninges

Cranial and Spinal Meninges

The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
