Second-harmonic imaging microscopy visualizes precancerous colorectal lesion changes. This label-free technique distinguishes normal from diseased tissues, aiding early diagnosis and treatment of colorectal diseases.
Area of Science:
- Biomedical Optics
- Gastroenterology
- Pathology
Background:
- Colorectal diseases, including precancerous lesions, require early detection for effective treatment.
- Current diagnostic methods may have limitations in real-time tissue analysis.
Purpose of the Study:
- To evaluate the potential of second-harmonic imaging microscopy for monitoring precancerous colorectal lesions.
- To identify morphologic changes associated with colorectal disease progression.
Main Methods:
- Second-harmonic imaging microscopy was employed to visualize colorectal tissues at various stages of disease.
- Morphologic variables of glands and lamina propria collagen were quantified.
Main Results:
- Significant changes in gland and lamina propria morphology were observed with disease progression.
- The microscopy enabled direct visualization of warning symptoms in precancerous lesions.
- Quantification of morphologic variables correlated with disease development.
Conclusions:
- Second-harmonic imaging microscopy offers a label-free method for distinguishing normal from precancerous colorectal tissues.
- This technique shows promise for the early diagnosis and treatment of colorectal diseases.

Harmonic Mean
Take the example of the speed of a car, which is the measure of the rate of distance traveled. If the vehicle traverses the same distance back-and-forth, its average speed equals the total distance traveled divided by the total time taken. However, if the car moves with varying speeds, then the arithmetic mean is more skewed...
