Higher Model Agreement
Dataset-2, acquired with a single scanner (UltraCOV) and standardized protocol, showed consistently higher agreement for both CM (Kqwc 0.66) and SM (Kqwc 0.79). This indicates that consistent acquisition reduces image variability, improving model performance.
Evaluating AI's ability to predict patient outcomes and inform clinical decisions.
0.66 Kqwc
Substantial prognostic-level agreement for the Classification Model on Dataset-1, indicating strong potential for predicting patient outcomes. (Source: Table 4, CM method, Dataset-1)
0.87 Kqwc
Substantial prognostic-level agreement for the Segmentation Model on Dataset-2, demonstrating its strong capability in predicting patient outcomes. (Source: Table 4, SM method, Dataset-2)
Segmentation Model's Adaptability for Prognosis
Challenge: Develop an AI model capable of predicting patient outcomes from LUS, comparable to expert clinicians, even if initially designed for a different task.
Solution: The Segmentation Model (SM), originally designed for artifact segmentation, was effectively repurposed for severity scoring. Its pre-processing pipeline standardizes input geometry, making it robust to scanner variations.
Impact: SM achieved prognostic-level agreement (Kqwc 0.51 on Dataset-1, 0.87 on Dataset-2) comparable to the Classification Model, demonstrating its ability to capture clinically relevant information for patient prognosis despite its initial design purpose. This indicates a flexible and generalizable approach for AI-assisted LUS.
