    The study benchmarks MedSigLIP against ImageNet-pretrained models for thyroid cytology using the ThyroidEffi 1.0 dataset.

  • 2

    EfficientNet achieved the highest macro-F1 score, followed closely by MedSigLIP, indicating competitive performance among models.

  • 3

    MedSigLIP demonstrated superior recall for the Suspicious class and the best calibration score compared to general-purpose encoders.

  • 4

    The findings suggest that model selection should prioritize calibration and sensitivity for borderline cases over aggregate accuracy.

  • 5

    Well-calibrated models like MedSigLIP may reduce misclassification in Bethesda V cases, highlighting the need for prospective validation.
