Research advances in visualized microspheres / 介入放射学杂志

ABSTRACT

Microspheres are commonly used as embolic materials in vascular interventional operations.However,due to the limitation of materials,almost all microspheres cannot be detected by imaging equipment in vivo.The visualization of microspheres refers to the addition of various materials to the microspheres that enable the microspheres to be displayed on the images of imaging equipment.In order to optimize the embolization process and facilitate postoperative follow-up,a lot of visualized microspheres have been reported so far,such as X-ray visualized microspheres,MRI visualized microspheres,ultrasonic visualized microspheres,etc.Clinical experience has shown that these microspheres can provide true spatial distribution and real-time intraoperative feedback,which contributes to the optimization,personalization,and improvement of vascular embolization technology.This paper aims to make a comprehensive review about the recent advances in researches about the above mentioned visualized microspheres.
