Terahertz Spectroscopy and Imaging: A Cutting-Edge Method for Diagnosing Digestive Cancers

Area of Science:

• Biomedical Optics
• Electromagnetic Wave Applications
• Cancer Diagnostics

Background:

• Digestive cancers are a significant global health concern with increasing incidence.
• Current diagnostic methods can be invasive or lack sensitivity for early detection.
• Terahertz (THz) waves, situated between microwave and infrared frequencies, offer non-ionizing and non-invasive imaging potential.

Purpose of the Study:

• To provide a comprehensive overview of Terahertz (THz)-based detection for digestive cancers.
• To summarize THz wave characteristics and their interaction with biological tissues.
• To review current research and potential clinical applications of THz technologies in digestive oncology.

Main Methods:

• Review of existing literature on THz wave applications in cancer detection.
• Analysis of THz spectroscopy, THz-tomography, and THz-endoscopy principles.
• Summarization of in vitro and in vivo studies for various digestive cancers.

Main Results:

• THz waves can differentiate molecules based on water content, aiding in tumor identification.
• THz-based technologies show promise for early detection and patient monitoring.
• Research has progressed in applying THz methods to oral, esophageal, gastric, colonic, hepatic, and pancreatic cancers.

Conclusions:

• Terahertz (THz) technology presents a valuable, non-invasive tool for the early detection and management of digestive cancers.
• Further development and clinical validation of THz-based systems are crucial for widespread adoption.
• THz imaging holds significant potential to improve patient outcomes in digestive oncology.
