Automatic Abdominal Aortic Aneurysm Diameter Measurement

Completed

• Conditions: AAA - Abdominal Aortic Aneurysm
• Interventions: Device: Philips EPIQ-7, Philips Healthcare, Bothell, WA, USA

• Registration Number: NCT05983016
• Lead Sponsor: Natasha Monzon Svendsen

Brief Summary

Managing abdominal aortic aneurysms currently relies on diameter assessment with ultrasound. Diameter reproducibility with two-dimensional ultrasound is challenging, and requires experienced operators. A novel automatic three-dimensional ultrasound system has the potential to facilitate more precise diameter measurements than two-dimensional ultrasound. This study aimed to assess the variance of abdominal aortic aneurysm diameter measurements among ultrasound novices and experts by comparing two-dimensional ultrasound with the three-dimensional ultrasound system in a clinical setting.

Ten patients under abdominal aortic aneurysm surveillance were examined by 29 ultrasound-operators: 13 experts and 16 novices. The experts were sonographers and physicians highly experienced in abdominal aortic aneurysm ultrasound, and the novices were medical students and junior residents with sparse ultrasound experience.
