Fig. 1: Qualitative performance of fine-tuned SAM on representative cases against ground truth on the EchoNet-dynamic test dataset.
From: Foundation versus domain-specific models for left ventricular segmentation on cardiac ultrasound
From top to bottom: 97.5th to 2.5th percentile of DSC. Panels a, b, and c are end-diastolic frames, and Panels d, e, and f are end-systolic frames. We observed that many of the poor-performance cases had suboptimal image qualities, such as weak LV endocardial borders or off-axis views (Panels c and f, suggesting the importance of good input image quality on model performance. Additionally, end-diastolic frames usually have a better delineation of borders than end-systolic frames, which is consistent with the model performance (end-diastolic slightly better than end-systolic).
