Prospective detection of cervical dysplasia with scanning angle-resolved low coherence interferometry

Area of Science:

• Biomedical Optics
• Gynecologic Oncology
• Medical Imaging

Background:

• Cervical dysplasia detection relies on histopathology.
• Optical methods offer non-invasive diagnostic potential.
• Angle-resolved low-coherence interferometry (a/LCI) measures nuclear morphology for disease detection.

Purpose of the Study:

• To evaluate a novel 2D scanning a/LCI instrument for cervical dysplasia detection.
• To compare the performance of the scanning a/LCI probe with a previous point-probe instrument.
• To assess the diagnostic accuracy of a/LCI using established criteria for cervical tissue classification.

Main Methods:

• Prospective clinical study involving 20 women at Jacobi Medical Center.
• Collected 80 a/LCI optical biopsies and co-registered physical biopsies.
• Utilized a novel 2D scanning a/LCI instrument for non-invasive optical biopsies.
• Classified tissue as non-dysplastic vs. dysplastic and low-risk vs. high-risk.

Main Results:

• High sensitivity for detecting cervical dysplasia (0.903 for non-dysplastic vs. dysplastic).
• Perfect sensitivity (1.000) for low-risk vs. high-risk classification.
• High negative predictive value (NPV) of 0.930 and 1.000 respectively.
• Demonstrated successful performance of the scanning a/LCI instrument.

Conclusions:

• The 2D scanning a/LCI instrument is effective for detecting cervical dysplasia.
• a/LCI shows significant clinical viability for non-invasive cervical disease detection.
• Established diagnostic criteria are applicable to the scanning a/LCI system.
