Robust Diagnostic Capabilities
The AI application achieved an impressive per-case sensitivity of 90.3% and specificity of 91.9% for acute cervical spine fracture (CSFx) diagnosis. The overall accuracy stood at 91.2%, with an Area Under the Receiver Operating Characteristic curve (AUC) of 0.91. A Matthews Correlation Coefficient (MCC) of 0.82 further indicates strong predictive performance, making this AI a reliable tool for initial screening and detection.
Precise Fracture Localization and Spinal Level Labeling
Beyond classification, the AI demonstrated high precision in identifying and localizing fractures with bounding boxes. Out of 192 bounding boxes generated for positive cases, 84.4% were true positives. Furthermore, for the 186 bounding boxes that included cervical spinal level labels, an impressive 97.3% were correctly labeled. This granular accuracy is critical for guiding clinicians to the exact location of injury.
Broad Generalizability Across Diverse Data
A key strength of this study is the validation of the AI application on a diverse dataset encompassing multiple centers, countries (U.S., France), and CT scanner vendors (GE, Philips, Siemens, Canon/Toshiba, Fujifilm). The diagnostic performance remained consistent across all subgroups (data sources, patient age, CT manufacturer), indicating high generalizability and robustness in varied real-world diagnostic settings.

Case Studies: AI in Action
Case 1: Precise Multi-Fracture Localization
In a 73-year-old female patient presenting with cervical trauma, the AI application accurately identified and localized four distinct acute fractures across C3, C4, and C5 vertebrae. Crucially, it provided precise spinal level labeling, even differentiating between multiple fractures on the same vertebra (e.g., C4-1, C4-2). This capability ensures comprehensive and accurate reporting for complex cases, significantly aiding clinical decision-making.
Case 2: Resolving Diagnostic Discrepancies
A challenging case involving a 69-year-old male with an acute fracture of the left transverse process of C7 initially resulted in disagreement between the first two radiologists. The AI application successfully identified and localized the fracture, demonstrating its potential to act as a valuable "second reader." This significantly reduces interpretation errors in nuanced or easily missed cases, improving diagnostic confidence and workflow efficiency.
