神经学神经学
放射学放射学是一门学科.
医疗成像医学成像

背景情况:

计算机断层扫描输液 (CTP) 对于在缺血性中风中延长再输液治疗窗口至关重要.
发表的CTP参数和值在研究中存在显著的变化.
精确识别缺血核心和半阴影对于治疗决策至关重要.

研究的目的:

系统地审查CTP参数的诊断准确性和识别成人中风患者缺血核心和半阴影的门.
调查CTP参数报告和值应用中的异质性.
为中风管理中CTP利用提供最佳实践信息.

主要方法:

按照PRISMA-DTA指南进行的系统审查.
在Medline,Embase,Cochrane图书馆搜索到2022年4月的关于中风中CTP的研究.
包括报告 perfusion 值和 CTP 与参考标准共同注册的研究;使用 QUADAS-2 和 STARD 评估质量.

主要成果:

包括24项研究;由于数据异质性,不能进行元分析.
相对脑血流 (rCBF) 是核心识别的常见参数,中位数值约为<30%,尽管早期再输血报告了较低的值.
15项研究使用了所有大脑区域的单一值,而不论血管性或组织类型.

结论:

一个单一的CTP值可能无法可靠地区分缺血半,核心和寡血症.
进一步细化CTP参数和值对于优化中风再注射治疗至关重要.
需要标准化的CTP分析来提高中风诊断和治疗的准确性.

Assessment of Diffusion and Perfusion

Assessment of Diffusion and Perfusion

Understanding and evaluating diffusion and perfusion is critical in assessing a patient's respiratory and circulatory health. These processes play key roles in maintaining the body's internal environment, ensuring that tissues receive adequate oxygen while waste products are efficiently removed.
The Role of Diffusion in Respiration
Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration. In the respiratory system, this...

Imaging Studies for Cardiovascular System V: CT

Imaging Studies for Cardiovascular System V: CT

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...
