脑小血管病国际影像标准2更新要点解读 Interpretation of the Updates on Standards for Reporting Vascular Changes on Neuroimaging 2

脑小血管病（cerebral small vessel disease,CSVD）是衰老过程中的常见疾病，可能会导致卒中、认知障碍、神经心理疾病或症状以及其他功能损害。CSVD常与神经退行性疾病并存，进一步加重认知损害及其他症状的发生，从而影响患者的日常生活能力。脑小血管病国际影像标准 1（standards for reporting vascular changes on neuroimaging-1，STRIVE-1）对结构MRI上所见的CSVD不同影像特征进行了分类和标准化。2023年发布的STRIVE-2进一步更新了CSVD血管变化的神经影像学指南。本文将对STRIVE-2更新要点进行解读。 Abstract: Cerebral small vessel disease (CSVD) is a common disease in the aging process that would result in stroke, cognitive disorder, neuropsychological disorders or symptoms, and other functional impairments. CSVD often co-exists with neurodegenerative diseases, further exacerbating cognitive impairment or other symptoms that affect the patient's ability to live independently. Standards for reporting vascular changes on neuroimaging 1 (STRIVE-1) classifies and standardizes the different features of CSVD seen on structural MRI. The STRIVE-2, published in 2023, further updates the neuroimaging guidelines for vascular changes in CSVD. This paper will explain the update points of STRIVE-2.
