“…We did not take into consideration the varying carotid size in our image database, since this issue is not extremely pertinent with the goal of this specific paper. However, we are currently validating the fact that the automatic IMT measurements remain accurate despite various carotid diameters, and in [35] we show that there is no dependency of our methodology with the diameter size of the carotid artery.…”

Automated and high performance carotid intima-media thickness (IMT) measurement is gaining increasing importance in clinical practice to assess the cardiovascular risk of patients. In this paper, we compare four fully automated IMT measurement techniques (CALEX, CAMES, CARES and CAUDLES) and one semi-automated technique (FOAM). We present our experience using these algorithms, whose lumen-intima and media-adventitia border estimation use different methods that can be: (a) edge-based; (b) training-based; (c) feature-based; or (d) directional Edge-Flow based. Our database (DB) consisted of 665 images that represented a multi-ethnic group and was acquired using four OEM scanners. The performance evaluation protocol adopted error measures, reproducibility measures, and Figure of Merit (FoM). FOAM showed the best performance, with an IMT bias equal to 0.025±0.225mm, and a FoM equal to 96.6%. Among the four automated methods, CARES showed the best results with a bias of 0.032±0.279mm, and a FoM to 95.6%, which was statistically comparable to that of FOAM performance in terms of accuracy and reproducibility. This is the first time that completely automated and user-driven techniques have been compared on a multi-ethnic dataset, acquired using multiple original equipment manufacturer (OEM) machines with different gain settings, representing normal and pathologic cases.

“…However, new minimally invasive procedures for aortic valve surgery are being developed and used, including ministernotomy and catheter-based approaches [130,131]. During the X-ray guided procedure in the catheterization laboratory, a compressed tissue heart valve is inserted through the femoral artery, positioned through the diseased aortic valve and then unfolded and fixed by inflating a balloon [132] or releasing a self-expanding stent support [133]. As in the case of radiofrequency ablation for the treatment of atrial fibrillation, the procedure is complicated by the fact that the heart and valve anatomy itself is hardly visible in the X-ray images.…”
