概括
计算机断层扫描输液 (CTP) 估计了中风患者进行内血管血栓切除术 (EVT) 的缺血核心体积. 与MRI心脏病发作体积的一致性在体积上是中等到良好的,但在空间上是差的,特别是在成功的再输注的情况下.
科学领域:
- 神经成像是一种神经成像.
- 放射学 放射学是一门学科.
- 脑卒中成像 脑卒中成像
背景情况:
- 计算机断层扫描输液 (CTP) 对于选择缺血性中风患者进行内血管血栓切除术 (EVT) 至关重要.
- 准确估计缺血核心对于治疗决策至关重要.
研究的目的:
- 为了评估CTP衍生的缺血核心体积的体积和空间一致性,使用不同的值与随访MRI扩散权重成像 (DWI) 心脏病发作体积相比.
- 为了评估接受EVT的患者的同意.
主要方法:
- 在2017年11月至2020年9月期间,对55名患者进行了回顾性分析,这些患者接受了EVT治疗,具有可用的基线CTP和后续DWI.
- 使用飞利浦IntelliSpace门户网站处理的CTP数据具有四个不同的值.
- 随访心脏病发作量按酒后驾驶情况划分.
主要成果:
- 中位数DWI心脏病发作体积为10毫升;中位数CTP估计核心体积在10-42毫升之间.
- 在完全再输血的患者中观察到中度至良好的体积一致性 (ICC 0.55-0.76).
- 在成功再输血的患者中发现体积一致性差 (ICC 0.36-0.45) 和空间一致性低 (Dice 0.17-0.19).
- 严重的核心高估发生在27%的病例中,特别是在第3方法和带T封闭的情况下.
结论:
- 在完全再注血的EVT治疗患者中,CTP提供了与DWI心脏病发作体积的中等到良好的体积一致.
- 空间协议仍然是经过测试的方法的一个限制.
- 结果表明,在EVT之前,需要仔细考虑CTP值,以准确评估中风.

Assessment of Diffusion and Perfusion
1.0K
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
45
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...

Radiological Investigation II: MRI and Ventilation Perfusion Scan
156
Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT
42
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...
