Abstract

fetched live from OpenAlex

Objective: The non-specific abdominal aortic aneurysm (AAA) is a local manifestation of a systemic disease, in which inflammation may play a role. This cardiovascular magnetic resonance (CMR) study utilizes a water-sensitive, T2- weighted, short tau inversion recovery sequence (T2-STIR) to identify vessel wall edema as a marker for inflammation. Methods: Twenty-two patients were included: 10 AAA patients, 10 healthy subjects, and two patients with known inflammation. MR T2-STIR images of aorta vessel wall and intraluminal thrombi were analyzed using OSIRIX software. Signal intensity values were normalized, and values from blinded and independent viewers were then averaged and analyzed using SPSS statistical software. The Kruskal-Wallis H test was used with post hoc analysis for differences of significance. Results: Average AAA anterior-posterior diameter was 5.9 ± 0.6cm (range, 5.3-7.0cm). The Kruskal-Wallis H test revealed a significant difference between independent samples (H(3) = 20.36, P < .001). There was no significant difference in average intensities between AAA and healthy subjects ( P = .766). Conclusion: This is the first study to examine edema in walls and thrombi of AAAs using T2-STIR imaging. No evidence of edema was identified in the aortic aneurysm wall, suggesting a lack of inflammatory activity.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
