Multi-Spectral Imaging of Circumscribed Choroidal Hemangioma Introduction
Bibliographic record
Abstract
BACKGROUND AND OBJECTIVE: To illustrate the features of a circumscribed choroidal hemangioma (CCH) using Annidis RHA multi-spectral imaging (MSI) technology (Annidis Corporation, Ottawa, Canada). This novel imaging technique uses non-overlapping, narrow-band LED light sources ranging from 520 nm to 940 nm to create a monochromatic series of en face fundus images and oxy/deoxyhemoglobin contrasted maps of the retina and choroid. PATIENTS AND METHODS: Annidis RHA MSI images were taken of a 67-year-old Chinese male with CCH. These en face fundus images are presented alongside the traditional fundus photograph, optical coherence tomography, and fluorescein and indocyanine green angiograms. RESULTS: Multi-spectral en face images of the outer retina and choroid demonstrated a clearly delineated lesion with a disorganized choroidal vascular network and increased reflectance/ oxyhemoglobin levels within. CONCLUSION: MSI technology is a noninvasive imaging technique that can depict the vascular features and choroidal oxygenation of CCH lesions and has a potential role in monitoring its growth complications.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
