Intracoronary near-infrared spectroscopy (NIRS) has been developed and validated for the detection of lipid-rich plaque in the coronary arteries. A combined NIRS and intravascular ultrasound catheter is currently in clinical use and has an emerging role in evaluating plaques both before and after percutaneous coronary intervention. NIRS has recently been shown to positively identify both vulnerable patients and vulnerable plaques. This review focuses on the principles and image interpretation of intracoronary NIRS, as well as its clinical applications, limitations, and future directions.
冠状动脉近红外光谱技术(NIRS)已被开发并验证可用于检测冠状动脉内富含脂质的斑块。一种结合了NIRS和血管内超声的导管目前正在临床应用中,并且在评估经皮冠状动脉介入治疗前后的斑块方面正发挥着越来越重要的作用。最近研究表明,NIRS能够可靠地识别出易损患者和易损斑块。本文综述聚焦于冠状动脉NIRS的原理、图像解读,以及其临床应用、局限性和未来发展方向。
