概括
一个新的计算管道准确地使用非对比CT (NCCT) 扫描来分类异常性正常压力头症 (NPH). 这种工具将NPH与头痛控制,阿尔茨海默氏症痴呆症和创伤后脑膜炎区分开来,有助于诊断.
科学领域:
- 神经成像是一种神经成像.
- 计算医学是一种计算医学.
- 放射学 放射学是一门学科.
背景情况:
- 异常性正常压力脑症 (NPH) 是一种神经疾病,常常被误诊.
- 精确区分NPH与其他神经系统疾病,如阿尔茨海默氏症痴呆症 (AD) 和创伤后脑膜炎 (PTE),对于有效治疗至关重要.
- 当前的诊断方法可能并不总是提供最终的分类,需要先进的分析工具.
研究的目的:
- 开发一个计算管道,从非对比CT (NCCT) 扫描中提取客观腹腔大病特征.
- 通过将其与头痛控制 (HCs),阿尔茨海默氏症痴呆症 (AD) 和创伤后脑膜炎 (PTE) 区分开来,准确地分类异常性正常压力脑膜炎 (NPH).
- 为了引入新的成像功能,用于心室隆骨病的评估.
主要方法:
- 对可能NPH (n=79),确定的NPH (DefNPH; n=29),AD (n=62),PTE (n=53) 和HC (n=59) 的患者的NCCT扫描进行了回顾性分析.
- 开发图像处理管道来提取特征,包括最大侧腔室偏心率 (MaxEccLV),代理角 (p-SA),埃文斯指数,角和CSF与大脑体积的比率.
- 应用t测试进行特征比较和多变量逻辑回归进行分类,并对NPH与HC分类器进行外部验证.
主要成果:
- 在NPH和对照组 (HC,AD,PTE) 之间观察到大多数提取特征的显著差异,除了p-SA.
- 获得了高分类性能:NPH与HC (AUC0.98),NPH与HC (AUC0.98) 相比. AD (AUC 0.94),NPH与PTE (AUC 0.96) 相比. 在这种情况下,
- 对NPH与HC分类器的外部验证给出了0.84的AUC,证明了强大的性能.
结论:
- 开发的计算框架,结合了像MaxEccLV这样的新功能,有效地量化了NCCT上的腹腔大脑病.
- 该管道成功地将NPH与HC,AD和PTE区分开来,表明其作为诊断辅助工具的潜力.
- 这种客观和易于使用的工具显示了NPH查的前景,并将其与类似的条件区分开来.

Computed Tomography
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Increased Intracranial Pressure l: Introduction
Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...
