研究目的: |
本项目拟结合能谱CT成像理论,重构能谱CT成像网络模型,改善图像质量实现多模态能谱CT图像信息深度耦合,提取脑部血流异常区域特征,结合病理分析特征,进而构建更加合理的急性大血管闭塞血栓来源的人工智能综合预测模型为辅助筛选急性缺血性脑卒中治疗方案提供更客观、更精准、更具普适性的信息,以支持个体化与个性化的临床决策,也为缺血性卒中患者急性管理提供新方向。 |

Objectives of Study: |
This study aims to integrate spectral CT imaging theory to reconstruct a spectral CT imaging network model, improve image quality, and achieve deep coupling of multimodal spectral CT image information. It will extract features of abnormal cerebral blood flow regions and combine these features with pathological analysis. Subsequently, a more rational artificial intelligence-based comprehensive prediction model for thrombus origin in acute large vessel occlusion will be constructed. This model is intended to provide more objective, accurate, and universally applicable information for assisting in the selection of treatment strategies for acute ischemic stroke, thereby supporting individualized and personalized clinical decision-making. It also offers a new direction for the acute management of ischemic stroke patients. |
