概括
在基底动脉封闭 (BAO) 中识别缺血核心对于中风治疗至关重要. 10毫升/100克/分钟以下的大脑血流 (CBF) 门准确地识别了 BAO 患者中血栓切除术后缺血核心.
科学领域:
- 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:
- 在计算机断层扫描 (CT) perfusion 中准确识别缺血核心对于基底动脉封闭 (BAO) 的预后预测和治疗决策至关重要.
- 目前用于确定BAO中缺血核心的方法在精确识别方面存在挑战.
研究的目的:
- 通过CT输液定义在BAO患者中识别缺血核心的最佳值.
- 通过使用Syngo.via软件,评估病变范围和缺血核心的空间分布的协议.
主要方法:
- 对91名BAO患者进行了回顾性分析,这些患者经历了成功的内血管血栓切除术.
- 使用大脑血流 (CBF) <10或15毫升/100克/分钟,大脑血体积 (CBV) <1.2毫升/100毫升和最大时间 (Tmax) >10秒的门估计缺血核心.
- 使用后循环阿尔伯塔中风计划早期CT得分和统计分析 (包括课内相关系数 (ICC) 和接收器操作特征 (ROC) 分析) 来评估心脏病发作的程度.
主要成果:
- CBF<10毫升/100克/分钟的值与随访心脏病发作程度 (ICC:0.81) 有很好的一致性,估计过高或低估值最小.
- 这一CBF值在检测中脑,关节和小脑梗塞方面表现最好,曲线下的面积 (AUC) 从0.79到0.90.
- 在CBF<15mL/100g/min和CBV<1.2mL/100mL的值显示不太理想的协议和性能.
结论:
- 10毫升/100克/分钟以下的CBF值是成功重新道化后在BAO患者中识别缺血核心的最佳标准.
- 该CBF值作为可靠的成像生物标志物,用于预测组织结果和指导BAO的治疗决策.
- 进一步验证这一值可以改善急性基底动脉中风患者的治疗.

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...
