1

The study assessed ultrasound-specific augmentation to enhance segmentation of ovarian tumors in B-mode and contrast-enhanced ultrasound images.
2

A lightweight Residual U-Net was used to compare performance with and without combined ultrasound-specific augmentation.
3

Combined augmentation improved segmentation metrics on contrast-enhanced ultrasound, including Dice and intersection over union.
4

Despite improvements, segmentation performance on contrast-enhanced ultrasound remained suboptimal, with over half of cases still below a Dice of 0.5.
5

The findings suggest that training-distribution design can enhance robustness against modality shifts without increasing inference-time complexity.

Coding for Ocular Tumors

Ocular tumor coding can be challenging because ocular oncology often involves evolving lesions, diagnostic uncertainty, and terminology that does not always translate cleanly into ICD-10-CM codes. Understanding how to distinguish benign, malignant, in situ, and uncertain histologic behavior neoplasms is essential for accurate coding, medical necessity, and audit defensibility.
