Transcranial focused ultrasound (FUS) is a versatile, MR-guided, incisionless intervention with diagnostic and therapeutic applications for neurologic and psychiatric diseases. It is currently FDA-approved as a thermoablative treatment of essential tremor and Parkinson disease. However, other applications of FUS including BBB opening for diagnostic and therapeutic applications, sonodynamic therapy, histotripsy, and low-intensity focused ultrasound neuromodulation are all in clinical trials. While FUS targeting for essential tremor and Parkinson disease has classically relied on an indirect, landmark-based approach, development of novel, advanced MR imaging techniques such as DTI tractography and fast gray matter acquisition T1 inversion recovery has the potential to improve individualized targeting and thus potentially enhance treatment response, decrease treatment times, and avoid adverse effects. As the technology advances and the number of clinical applications increases, the role of the neuroradiologist on a multidisciplinary team will be essential in pairing advanced structural and functional imaging to further this image-guided procedure via a precision medicine approach. This multi-institutional report, written by an experienced team of neuroradiologists, neurosurgeons, and neurologists, summarizes current practices, the use of advanced imaging techniques for transcranial MR-guided high-intensity FUS, recommendations for clinical implementation, and emerging clinical indications.
经颅聚焦超声(FUS)是一种多功能的、磁共振引导的无创干预技术,在神经和精神疾病的诊断及治疗中均有应用。它目前已获得美国食品药品监督管理局(FDA)批准,可用于原发性震颤和帕金森病的热消融治疗。然而,FUS的其他应用,包括用于诊断和治疗的血脑屏障开放、声动力疗法、组织粉碎术以及低强度聚焦超声神经调节,均处于临床试验阶段。虽然针对原发性震颤和帕金森病的FUS传统上依赖于间接的、基于标志物的方法,但诸如扩散张量成像(DTI)纤维束成像和快速灰质采集T1反转恢复等新型先进磁共振成像技术的发展,有可能改善个体化靶向,从而潜在地提高治疗反应、缩短治疗时间并避免不良反应。随着技术的进步和临床应用数量的增加,神经放射科医生在多学科团队中的作用对于通过精准医学方法将先进的结构和功能成像与这种影像引导程序相结合至关重要。这份多机构报告由经验丰富的神经放射科医生、神经外科医生和神经科医生团队撰写,总结了当前的实践、经颅磁共振引导高强度FUS的先进成像技术应用、临床实施建议以及新出现的临床适应症。
