Light and sound - emerging imaging techniques for inflammatory bowel disease

Area of Science:

• Gastroenterology and Medical Imaging

Background:

• Inflammatory bowel disease (IBD) requires frequent monitoring for disease activity and cancer risk.
• Conventional endoscopy with biopsy is the gold standard but is invasive.

Purpose of the Study:

• To review novel, non-radiant, quantitative imaging methods for IBD assessment.
• To highlight the potential of these techniques for diagnosis, activity assessment, and cancer surveillance.

Main Methods:

• Review of established and advanced imaging techniques including light-based (e.g., wide-view full-spectrum endoscopy, chromoendoscopy, autofluorescence endoscopy, endocytoscopy, confocal laser endoscopy, multiphoton endoscopy, molecular imaging endoscopy) and sound-based modalities (e.g., B-mode and Doppler ultrasound, contrast-enhanced ultrasound, ultrasound molecular imaging, elastography).

Main Results:

• New imaging modalities offer functional and molecular insights beyond conventional methods.
• These techniques show promise in predicting personalized therapeutic responses.
• Potential to reduce the frequency of invasive procedures.

Conclusions:

• Advanced imaging techniques are emerging as powerful tools for IBD management.
• These methods can aid in initial diagnosis, disease activity assessment, and cancer surveillance.
• Future applications may lead to more personalized and less invasive patient care.
