Results
Of the 119 carotids analysed,
in 9 cases the image quality was insufficient,
due to dental hardware which made the semiautomatic plaque quantification measurement impossible.
In 3 cases the stenosis was total and there was an occlusion of the vessel; this patients have been exluded as well from the calculations.
In 21 cases the stenosis was significative according to the NASCET criteria (stenosis > 50%). There is almost no correlation between the angle value and the fatty plaque percentage (r -0.005784,
significance level p= 0.9533).
The correlation coefficient between the angle value and the calcified plaque percentage is 0.1456.
The biggest correlation is between CCA-ICA angle values and a plaque composed mainly of fibrous HU voxels (r= 0.2130,
significance level p= 0.0375).
