摘要
超声造影(CEUS)可有效地评价正常脑微循环灌注、缺血状态下的脑组织灌注,并可评估脑血管内支架植入术后血管的通畅情况。应用CEUS不仅能更加精确地测定脑出血容积,而且能够发现肿瘤术后的残留。CEUS除可应用于脑血栓溶栓治疗中,也有望应用于脑外伤中。本文对CEUS在脑灌注成像中的应用作一综述。
Ultrasound brain perfusion imaging can evaluate brain perfusion in normal and pathological conditions. After basilar stent implantation, contrast-enhanced ultrasound （CEUS） can show normal visualization of color flow within the stent and provide essential functional information by evaluation of blood flow velocities. Furthermore, CEUS can estimate the volume of brain hemorrhage and readily identify residual tumor. CEUS can be used in thrombotysis, and will be applied in cerebral trauma. The value of CEUS in brain perfusion imaging was reviewed in this article.
