There was no interobserver difference between the two observers in either the CTA or the MRI interpretation.
For further analysis the second CTA segmentation data was used.
The segmented lesions were located in the bifurcation in 73.3%.
Positive remodeling was found in 60%.
There was no calcification in 20% of patients.
28.3% had severe,
51.6% had minor calcifications.
There was significant correlation (p=0.047) between the higher volume of necrotic components and the higher incidence of relevant side ischemic lesions according to the univariate linear regression analysis.

According to our ROC analysis the volume of necrotic components could moderately predict the performace on Fazekas scale (AUC=0.62).
