概括
顺序获取双能CT (SADE) 显示低灵敏度,但在机械血栓切除术 (MT) 后检测内出血 (ICH) 的特异性高. 它可靠地区分了对比性染色 (CS) 和ICH,尽管可能会出现错误的注册工件.
科学领域:
- 放射学 放射学是一门学科.
- 神经学 神经学
- 医疗成像医学成像
背景情况:
- 在机械血栓切除术 (MT) 后,区分对比染色 (CS) 和内出血 (ICH) 是至关重要的.
- 双源双能计算断层扫描 (DECT) 已经显示出区分这些条件的潜力.
研究的目的:
- 评估顺序采集DECT (SADE) 的诊断准确性,用于在MT之后识别ICH.
- 评估SADE在区分CS和ICH方面的可靠性.
主要方法:
- 追溯分析56名为急性缺血性中风接受MT治疗的患者.
- 使用DECT获取虚拟非对比 (VNC) 和地图图像.
- 高衰减 (HA) 区域被归类为ICH或CS,通过后续成像验证准确性.
主要成果:
- 总共确定了129个HA区域,109个仅为CS地区,20个是ICH和CS地区.
- 检测出血的灵敏度,特异性和准确性分别为20.9%,91.9%和65.8%.
- 在3.6%的VNC图像中出现了错误的注册文物.
结论:
- 由于延迟的出血变化,SADE在MT后检测ICH的灵敏度较低.
- 然而,SADE在区分CS和ICH方面表现出高度的特异性和可靠性.
- 应该考虑SADE的错误注册文物的可能性.

9.6K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

04:10What is Energy?
58.9K
The universe is composed of matter in different forms, and all forms of matter contain energy. The different forms of energy on Earth originate from the Sun — the ultimate energy source. Plants capture light energy from the Sun, and, via the process of photosynthesis, convert it into chemical energy. This stored energy from plants can be harnessed in many ways. For example, eating plant products as food provides energy for our body to function, and burning wood or coal (fossilized...

Free energy—abbreviated as G for the scientist Gibbs who discovered it—is a measurement of useful energy that can be extracted from a reaction to do work. It is the energy in a chemical reaction that is available after entropy is accounted for. Reactions that take in energy are considered endergonic and reactions that release energy are exergonic. Plants carry out endergonic reactions by taking in sunlight and carbon dioxide to produce glucose and oxygen. Animals, in turn, break...

03:25Free Energy Changes for Nonstandard States
13.6K
The free energy change for a process taking place with reactants and products present under nonstandard conditions (pressures other than 1 bar; concentrations other than 1 M) is related to the standard free energy change according to this equation:

02:00Internal Energy
36.7K
The total of all possible kinds of energy present in a substance is called the internal energy (U), sometimes symbolized as E. Suppose a system with initial internal energy, Uinitial, undergoes a change in energy (transfer of work or heat), and the final internal energy of the system is Ufinal. Change in internal energy equals the difference between Ufinal and Uinitial.
