Pre-surgical and Post-surgical Aortic Aneurysm Maximum Diameter Measurement: Full Automation by Artificial Intelligence

The aim of this study was to evaluate an automatic, deep learning based method (Augmented Radiology for Vascular Aneurysm [ARVA]), detect and assess maximum aortic diameter, providing cross sectional outer wall measurements. Accurate external diameter measurement is performed along the entire aorta, from ascending aorta iliac bifurcations, on both pre- post-operative contrast enhanced computed tomography angiography (CTA) scans. A training database 489 CTAs used train a pipeline neural networks automatic Another 62 CTAs, including controls, aneurysmal aortas, dissections scanned before and/or after endovascular or open repair, validation. measurements made by ARVA were compared with those seven clinicians validation dataset. median absolute difference respect expert’s ranged 1 mm 2 among all annotators, while reported 1.2 mm. performance falls within interannotator variability, making it potentially reliable solution assisting clinical practice.
