与现有的颅内药物递送方法相比,具有微泡的聚焦超声在破坏血脑屏障方面具有前所未有的优势,以及影响其安全性和有效性的大量可调参数。这篇综述提供了一个工程的角度对国家的最先进的技术,考虑的作用机制,影响微泡性能,超声参数和生理变量,以及安全性和潜在的治疗应用。重点是使用统一的参数,如微泡体积剂量(MVD)和超声机械指数,以优化程序和建立安全限值。它的结论是,虽然疗效已被证明在几个动物模型与广泛的有效载荷,可接受的安全措施,应采取加速合作,提高理解和临床相关性。
Focused ultrasound with microbubbles promises unprecedented advantages for blood-brain barrier disruption over existing intracranial drug delivery methods, as well as a significant number of tunable parameters that affect its safety and efficacy. This review provides an engineering perspective on the state-of-the-art of the technology, considering the mechanism of action, effects of microbubble properties, ultrasound parameters and physiological variables, as well as safety and potential therapeutic applications. Emphasis is placed on the use of unified parameters, such as microbubble volume dose (MVD) and ultrasound mechanical index, to optimize the procedure and establish safety limits. It is concluded that, while efficacy has been demonstrated in several animal models with a wide range of payloads, acceptable measures of safety should be adopted to accelerate collaboration and improve understanding and clinical relevance.
