ObjectivesThis study aims to assess the distribution and interrelation of the presence of calcifications along the course of the internal carotid artery (ICA), by cone beam CT (CBCT), and to associate the severity of their depiction with the allocation within the segments of ICA, gender and age.Study Design161 CBCTs with intracranial calcifications were evaluated on their allocation and severity within the segments of ICA using a documented visual scale.ResultsCalcifications were detected along the petrous (C2-11.8%), lacerum (C3-23.6%), cavernous (C4-92.5%), and ophthalmic-clinoid (C5/C6-65.8%) segments. Friedman test showed significant difference in the severity distribution among these segments; the highest degree was found in the C4 segment (P<0.05). Wilcoxon signed-rank test showed no significant difference between calcifications on the right or left side or, between severities within C1 (extracranial) and C5/C6 segments. Chi-square test showed that the severity and allocation of calcifications are not influenced by gender; it also showed that their severity increases with age (P<0.05).ConclusionsIn the cohort studied the incidence of calcifications increases throughout the C1, C5/C6, and C4 segments. More severe calcifications were found at the C4, C1, and C5/C6 segments in decreasing order, yet increasing with age, regardless of gender.
