|a Embolization has been an important minimally invasive therapy for occlusion of malfunctioned vasculature and tumor treatment via target delivering embolic agents. The limitation of conventional embolic agents, such as fabrication process, precipitation time, invisibility, and lack of integrated functions often leads to insufficient embolization efficacy. To overcome these drawbacks, a multifunctional bismuth (Bi)-based liquid embolic agent for simultaneous realization of embolotherapy, thermotherapy, as well as high-contrast biomedical imaging is proposed. Benefitting from the suitable melting point, flexible nature, metallic merit, and easygoing operation via injection, the versatile embolic agent can achieve rapid liquid-solid phase transition, magnetic hyperthermia, and multimodal imaging capability. The Bi-based materials are demonstrated with excellent arteriovenous embolization efficiency and favorable biocompatibility according to in vivo investigations. Introduction of the liquid embolic agent to tumor arteries achieves evident tumor regression and rather clear imaging under computed tomography (CT), magnetic resonance imaging (MRI), and thermographs for consistently tracking the implants over the biological body. Further, the combined therapy coupled with thermotherapy exhibits improved therapeutic efficiency with formation of necrosis and total tumor eradiation at day 15 after the treatment. The present innovative embolic agent and the surgical principle provide a promising modality for embolization and potential theranostic platform of tumors
