Abstract Funding Acknowledgements Type of funding sources: Other. Main source(s): Self Introduction An abdominal aortic aneurysm is a life-threatening condition and the risk rupture higher with increased maximum diameter (Dmax) expansion rate. Therefore, AAAs require regular monitoring Dmax. The most commonly used imaging technique for measuring AAA size two-dimensional ultrasonography (2-D US), closely followed by computed tomography (CT). Purpose : This study sought to evaluate accuracy novel semi-automated 3-D (3-D US) system its comparison CT as reference. Methods A total 66 patients were prospectively recruited in an outpatient setting. Two-dimensional US images attained single-sweep volumetric transducer. Dmax vessel area slice measured 2-D US, CT. vessel, lumen, thrombus areas also using Results It was found that values from demonstrate better agreement (R2 = 0.971) than 0.929). Overall, underestimated compared (30.8 ± 13.1mm vs. 34.4 11.6 mm). all demonstrated 0.988 0.961 R2 0.879 0.829 0.963 0.849 thrombus). Conclusion Our concludes our analysis provides more accurate data US. application aorta assessment easy accurate. Figure. Comparison on three modalities
