P8. 04 Carotid Intima-Media Thickness: Comparisons Between Semiautomatic Edge Detection Method Versus a New Automatic Echo Tracking System

摘要: RationaleThe intima-media thickness (IMT) of the common carotid artery is a widely used clinical marker of cardiovascular diseases. To date, IMT is measured from longitudinal B-mode ultrasound images using manual or imaging analysis methods. Real-time automatic tracking of the lumen-intima and media-adventitia echoes using multi-echotracking technology could overcome some limits of manual and imaging analysis methods.Material and methodsCommon carotid intima-media thickness measured with a new multi-echotracking system (QIMT – Esaote - Italy) was compared to a semi-automatic edge detection imaging analysis method (IMT@televasc, www.televasc.fr, France) from B-mode ultrasound images.Results93 scans were analyzed with both techniques on the same scans and from both carotids in 57 patients (age 55 +/− 17, 34 males). Mean QIMT was higher than IMT@televasc (690+/−173 vs 662 …
