Summary
Near-infrared imaging enhances cancer surgery by providing real-time visualization of tumors. This optical imaging technique improves tumor margin assessment, crucial for patient prognosis and guiding surgical decisions.
Area of Science:
- Oncology
- Medical Imaging
- Surgical Technology
Background:
- Accurate intra-operative assessment of tumor margins is vital for cancer patient prognosis.
- Current methods rely on visual appearance and palpation, which can be subjective.
- Optical imaging offers real-time visualization to guide surgeons during procedures.
Purpose of the Study:
- To review current optical imaging techniques for image-guided cancer surgery.
- To discuss near-infrared (NIR) light advantages in surgical visualization.
- To explore molecular contrast agents and future perspectives in cancer surgery.
Main Methods:
- Review of existing literature on optical imaging techniques in cancer surgery.
- Analysis of near-infrared (NIR) imaging principles and benefits.
- Overview of various contrast agents and camera systems used in image-guided surgery.
Main Results:
- Near-infrared (NIR) imaging offers enhanced tissue penetration and signal-to-background ratio for contrast agents.
- A wide range of molecular contrast agents targeting cancer hallmarks are available.
- Current techniques, contrast agents, and camera systems are detailed.
Conclusions:
- Optical imaging, particularly NIR, is a promising tool for intra-operative image-guided cancer surgery.
- Molecular contrast agents offer targeted visualization of cancer.
- Future advancements hold potential for improved surgical outcomes in oncology.
