脑微出血及其磁共振成像检查的研究进展

Research Progress on Cerebral Microbleeds and Its Magnetic Resonance Imaging Examination

脑微出血(cerebral microbleeds, CMBs)是一种由于各种危险因素破坏血脑屏障或损伤血管内皮导致的微小出血灶。CMBs的危险因素包括年龄、高血压、脑淀粉样血管病、糖尿病、高同型半胱氨酸血症、炎症反应、药物及手术等。随着磁共振成像技术持续发展,不断提高了对微小出血灶的检测和定位准确性。总之,脑微出血是一个值得关注和研究的话题,需要进一步深入研究其发生机制和危险因素,同时也需要继续发展和优化磁共振成像技术,以提高对脑微出血的检测和定位准确性,为临床诊断和治疗提供更准确的依据。

Cerebral microbleeds (CMBs) are tiny hemorrhagic foci resulting from various risk factors that disrupt the blood-brain barrier or damage vascular endothelium. These risk factors encompass age, hypertension, cerebral amyloid angiopathy, diabetes, hyperhomocysteinemia, inflammatory reactions, medications, and surgical procedures. The continuous advancement of magnetic resonance imaging (MRI) technology has progressively improved the accuracy of detecting and locating these minute hemorrhagic foci. In conclusion, CMBs is a noteworthy topic for research, requiring further investigation into its pathogenesis and risk factors. Additionally, there is a need to continue developing and optimizing MRI technology to enhance the detection and localization accuracy of CMBs, thereby providing a more precise basis for clinical diagnosis and treatment.
