What does this research mean for the field?

AI-based vessel-suppressed imaging demonstrates high sensitivity (92%) for detecting malignant pulmonary nodules across various sizes and morphologies, whereas computer-aided detection (CADe) annotation sensitivity (72%) is significantly limited by nodule type and location. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To assess the real-world diagnostic sensitivity of an AI-based vessel suppression and computer-aided detection system for identifying malignant lung nodules and determine features linked to detection failure.

Implication

Retrospective study reveals vessel-suppressed imaging outperforms automated detection for malignant nodules in lung cancer screening, highlighting sensitivity drops for non-solid lesions.

Key Points

To assess the real-world diagnostic sensitivity of an AI-based vessel suppression and computer-aided detection system for identifying malignant lung nodules and determine features linked to detection failure.
Retrospective review of N=129 patients diagnosed with lung cancer within a lung cancer screening program after deployment of the ClearRead VIS/CADe platform (August 2023 to June 2025).
A fellowship-trained cardiothoracic radiologist evaluated nodule size, morphology, anatomical location, and presence on clinical reports, CADe marks, and vessel-suppressed CT images.
Multivariable logistic regression was performed on nodules <30 mm to identify independent predictors of automated CADe annotation.
Overall sensitivity on diagnosis CT was 72% (93/129) for CADe automated annotation compared with 92% (119/129) for vessel-suppressed imaging.
CADe sensitivity varied significantly by nodule size (P<0.001) and morphology (P<0.001), detecting 80% of solid, 75% of part-solid, 38% of ground-glass, and 13% of cystic nodules.
For nodules <30 mm, subpleural and paramediastinal locations were independently associated with significantly reduced CADe sensitivity (P<0.05).
