Intraoperative near-infrared imaging using indocyanine green has been increasingly used in procedural medical fields in recent years. The purpose of our work is to provide a general overview of the use of indocyanine green (ICG) in procedural medical fields. We reviewed publications posted in PubMed, whose authors used ICG in their research, but also daily surgical practice. Many large studies have demonstrated the usefulness of this method. Currently, new directions for the use of this dye are being sought. In the future, the use of ICG in near-infrared (NIR) imaging may become a standard used in daily medical practice.

Material and methods:
A review of the available literature was conducted using the PubMed. The search terms ''ICG'', ''indocyanine green'', ''indocyanine green fluorescence'', and ''NIR'' were used.

We analyzed several dozen articles from the large database available in PubMed. ICG is currently used in many different fields of medicine. Below we list the applications found in this review.

Indocyanine green (ICG) has demonstrated utility across various surgical disciplines within the medical field. A growing body of research has elucidated the multiple advantages conferred by this dye, thereby propelling its increased adoption by researchers and practitioners. Despite these advances, there remains a need for extensive research before ICG can be integrated into routine clinical applications.
