Purpose

The purpose of this study was to develop a machine learning-based algorithm based on a combination of magnetic resonance imaging (magnetic resonance imaging) and color-Doppler ultrasound (color-Doppler ultrasound) to characterize lacrimal gland lesions.

Methods

All patients with a lacrimal gland lesion who underwent magnetic resonance imaging examination and color-Doppler ultrasound between 2014 and 2025 were retrospectively included.

n = 130 lesions
Results

correctly told cancer from non-cancer lesions far above chance, though small study, wide confidence range

AUC 0.88 (95% CI 0.69 to 1)
null = 00.691
CI excludes the null - significant
More results

In multiclass analysis (benign non-epithelial, benign epithelial, malignant non-epithelial and malignant epithelial), the random forest yielded a macro-averaged AUC of 0.857 (95% CI: 0.722-0.972) for the all-features model.

More results

A 5-top features signature comprising apparent diffusion coefficient and resistance index values, echogenicity, age and lesion type (infiltrative vs. well-delineated mass), yielded an AUC of 0.785 (95% CI: 0.641-0.941) to distinguish between the four classes.

“
Conclusion · 1 of 2

A combination of magnetic resonance imaging and color-Doppler ultrasound features demonstrated high diagnostic performance for characterizing lacrimal gland lesions.

Conclusion · 2 of 2

A simplified 5-feature signature showed similar diagnostic performance compared to the all-features model and warrants prospective multicenter validation for clinical application.
