摘要
背景:目前主要的神经成像方式,如磁共振成像、计算机断层扫描和高分辨率超声,均无法为医生提供术中实时定位图像。随着近红外荧光成像技术应用于临床,手术目标区域的直接可视化成为现实,这为神经的术中实时识别提供了新的方案。目的:归纳并总结近红外荧光成像技术实现术中神经成像的研究进展。方法:以“近红外荧光成像,光学成像,神经成像”为中文检索词,以“near-infrared fluorescence imaging,optical imaging,nerve imaging”为英文检索词,分别检索万方数据、中国知网及PubMed数据库。检索时间范围重点为2010年1月至2023年7月,同时纳入少数经典远期文献,通过阅读文题和摘要进行初步筛选,排除中英文文献重复性研究、低质量期刊及内容不相关的文献,最后纳入69篇文献进行综述。结果与结论:(1)吲哚菁绿引导下的近红外荧光成像在临床上已被用于术中血管、输尿管和胆管等管状器官以及各种肿瘤的识别与定位,是目前在精准外科手术中应用比较成熟的术中成像方法。(2)在近红外荧光成像技术实现术中神经荧光成像的研究中,吲哚菁绿是目前唯一的一种应用于临床研究的近红外荧光染料。(3)理想神经显影剂应该具有以下特点:在围术期容易给药,logD在pH=7.4时数值为0.5-3.0,分子质量<500 Da,有近红外窗口中的激发和发射波长,能够在神经组织中长时间保留,具有较高的SBR值以及较高的安全性。(4)未来近红外神经荧光显影剂的开发中,研究者们应该将重心放在合成吲哚菁绿与神经特异性靶点的复合物中。(5)在应用前景方面,该技术不仅能使术中神经荧光成像将成为现实,而且在原位监测神经再生以及诊断神经系统疾病方面也将取得巨大突破。
BACKGROUND:Existing neuroimaging techniques,including magnetic resonance imaging,computed tomography,and high-resolution ultrasound,lack the capability to provide real-time intraoperative positioning images to surgeons.However,the clinical implementation of near-infrared fluorescence imaging technology has made it possible to directly visualize surgical target areas,offering a novel solution for real-time nerve identification during surgery.OBJECTIVE:To provide a summary and overview of the research progress in near-infrared fluorescence imaging technology for intraoperative neuroimaging.METHODS:The first author used the computer to search for the documents published from January 2010 to July 2023 in WanFang,CNKI,and PubMed with the key words of“near-infrared fluorescence imaging,optical imaging,nerve imaging”in Chinese and English.A few classic old documents were also included.Initial screening was performed by reading the titles and abstracts;duplicate,low-quality,and irrelevant content documents were excluded.A total of 69 articles were finally included for review.RESULTS AND CONCLUSION:Near-infrared fluorescence imaging guided by indocyanine green has been clinically used to identify and locate tubular organs such as blood vessels,ureters,and bile ducts,as well as various tumors during surgery.This technique is currently considered a well-established imaging method in precision surgery.In the field of intraoperative neurofluorescence imaging,indocyanine green is currently the only near-infrared fluorescent dye used in clinical research.The ideal neuroimaging agent should possess certain characteristics,including easy administration in the perioperative period,logD between 0.5 and 3 at pH=7.4,molecular mass below 500 Da,excitation and emission wavelengths within the near-infrared window,long-term retention in nerve tissue,high signal-to-background ratio,and high safety.In the future,the development of near-infrared neurofluorescence imaging agents should focus on synthesizing complexes of indocyanine green and neural-specific targets.This technology not only enables intraoperative neurofluorescence imaging,but also holds promising prospects for in-situ monitoring of nerve regeneration and diagnosis of neurological diseases.
