Fig. 4: ONCOPILOT Integration Into Radiologist’s Workflow.
From: A promptable CT foundation model for solid tumor evaluation
A Diagram and results comparing ONCOPILOT in point, point-edit, and bbox modes against three radiologists for the long-axis measurement of diverse oncological lesions. Median absolute error (mm) and median relative error (% of lesion size) are shown. p values from t-tests compare ONCOPILOT models to radiologists for long-axis measurement error, without statistical significance p ≥ 0.05. The long axis is the longest line in the axial plane across the predicted 3D mask. B Boxplot (bottom) of ONCOPILOT's tumors long-axis measurement performance against radiologists. Left: median absolute error (mm) vs. ground truth. Right: median relative error (% of lesion size). Median and interquartile ranges are shown. C Diagram of an experiment evaluating radiologists' inter-operator variability and measurement time while measuring tumors' long-axis using a digital viewer for manual vs. ONCOPILOT-assisted (bbox mode) long-axis assessments. D Boxplots show radiologists' inter-operator variability in measurement error (left) and measurement time (right) using manual vs. ONCOPILOT-assisted annotations across diverse tumors, with t-test p values; n = 3.
