Endoscopic applications of optical coherence tomography.

Area of Science:

• Medical Imaging
• Gastroenterology
• Ophthalmology

Background:

• Optical Coherence Tomography (OCT) is a non-invasive imaging modality.
• Endoscopic OCT (EOCT) adapts OCT for internal organ visualization.
• Clinical validation of EOCT for mucous membrane diagnosis is ongoing.

Purpose of the Study:

• To evaluate the clinical applications and diagnostic capabilities of EOCT.
• To assess EOCT's role in managing conditions of internal organs.
• To establish EOCT's utility in various medical specialties.

Main Methods:

• Application of a novel endoscopic optical coherence tomography (EOCT) system.
• Clinical experiments involving over 100 patients.
• Focused examination of larynx, bladder, and uterine cervix, plus laparoscopic abdominal imaging.

Main Results:

• EOCT demonstrated effectiveness in imaging human internal organs, particularly mucous membranes.
• The system proved useful for directed biopsy, functional state monitoring, treatment guidance, and post-operative recovery assessment.
• EOCT provided informative results for organs with distinct epithelial-stromal layers separated by a basal membrane.

Conclusions:

• EOCT is a valuable tool for diagnosing human mucous membranes and internal organs.
• EOCT offers diverse clinical applications, including biopsy guidance and treatment monitoring.
• Laparoscopic OCT represents a novel approach for abdominal organ examination.
