Introduction: Although the Artlab® echotracking device (Artlab, Esaote) determines common carotid artery (CCA) far wall thickness (FW-IMT) with high resolution, the near wall thickness (NW-IMT) is still challenging. New ultrasound software (CAAS-US, Pie medical Imaging) was developed for NW-FW-IMT measurement from radiofrequency signal.

Objectives: To compare CCA IMT between CAAS-US and standard Artlab, and to assess CAAS-US determination of NW-IMT and both near and far wall IMT variations during the cardiac cycle, in 38 treated hypertensive (HT) and 18 normotensive (NT) patients.

Methods: Diastolic outer diameter (Dd) and FW-IMT were determined with CAAS-US and Artlab. Bland-Altman test and Pearson’s correlation coefficient (R) were used to compare methodologies. With CAAS-US, NW-IMT and FW-IMT were compared. Systolo(s)-diastolic(d) variations of IMT and outer D were calculated: ΔIMT ((IMTs - IMTd)/IMTd) of NW and FW were compared to ΔD ((Ds - Dd)/Dd).

Results: No significant differences in CCA Dd and FW-IMTd were observed between two methods (R=0.97, RMSE=0.124 mm and R=0.91, RMSE=0.065 mm, respectively p<0.0001). IMTd between near and far wall are significantly correlated (R=0.73, RMSE=0.117 mm, p<0.0001). FW ΔIMT is significantly correlated to ΔD (R=0.57, RMSE=0.036 mm, p=0.0002) whereas NW ΔIMT is not (R=0.30, RMSE=0.073 mm, p=0.065).

Conclusion: CAAS-US allows determination of both near and far wall CCA IMT. Whereas FW-IMT variation during the cardiac cycle is measurable, NW-IMT is less precise and remains a challenging. These findings added to CAAS-US plaque contours ability may be useful to estimate more completely the real state of the carotid artery atherosclerotic process.
