“…The vertebral artery is the second most common artery affected by calcification. 12 13 Calcification was identified in one or both intracranial vertebral arteries in 3.4% of 3,648 CT scans, 31 and was more frequent in the higher age groups. Another study that involved 490 Chinese hospital patients found a higher incidence of intracranial vertebral artery calcification (20%).…”

Intracranial arterial calcification (IAC) is an easily identifiable entity on plain head computed tomography scans. Recent studies have found high prevalence rates for IAC worldwide, and this may be associated with ischemic stroke and cognitive decline. Aging, traditional cardiovascular risk factors, and chronic kidney disease have been found to be associated with IAC. The severity of IAC can be assessed using different visual grading scales or various quantitative methods (by measuring volume or intensity). An objective method for assessing IAC using consistent criteria is urgently required to facilitate comparisons between multiple studies involving diverse populations. There is accumulating evidence from clinical studies that IAC could be utilized as an indicator of intracranial atherosclerosis. However, the pathophysiology underlying the potential correlation between IAC and ischemic stroke—through direct arterial stenosis or plaque stability—remains to be determined. More well-designed clinical studies are needed to explore the predictive values of IAC in vascular events and the underlying pathophysiological mechanisms.

“…Complementary to HR-VWI, computed tomographic angiography (CTA) could provide incremental value in the assessment of plaque vulnerability 11 and enable the quantification of vascular calcification. In contrast to the intracranial internal carotid artery, calcification of the vertebrobasilar artery was mainly found in the elderly 12 and highly correlated with luminal stenosis, 13 indicating its atherosclerotic origin. The amount and pattern of calcification have been reported to predict different risks of cardiovascular events.…”

Objectives Diabetes mellitus is significantly associated with posterior circulation ischemic stroke. We aimed to compare the characteristics of vertebrobasilar plaques in symptomatic patients with and without diabetes using high-resolution vessel wall magnetic resonance imaging and computed tomographic angiography. Methods From April 2017 to May 2021, cases from patients with transient ischemic attack or stroke in the posterior circulation territory who underwent high-resolution vessel wall magnetic resonance imaging and computed tomographic angiography were reviewed. Characteristics of culprit vertebrobasilar plaques were compared between patients with and without diabetes. Multivariate regression analysis was performed to assess the correlation between culprit plaque characteristics and diabetes. Results A total of 148 patients were included and 75 patients were diagnosed with diabetes mellitus. Patients with diabetes had more intraplaque hemorrhage, calcification, spotty calcification presence, and higher calcification volume (all p < 0.05) compared with those without diabetes. Multivariate analysis demonstrated differences in the presence of intraplaque hemorrhage ( p = 0.045) and number of spotty calcifications ( p = 0.047) were statistically significant after adjusting for baseline characteristics. Conclusions Symptomatic patients with diabetes have a higher incidence of intraplaque hemorrhage and larger calcification burden than those without diabetes, indicating the association of diabetes with more advanced plaque features in the posterior circulation.

“…In a previous study, a high correlation was observed between vertebral artery calcification on CT and vertebral artery stenosis on cerebral angiography. [3] Similarly, "dense basilar artery" is thought to represent basilar artery thrombosis or embolism and an early sign suggestive of basilar territory infarction. [4] Accepted on 01.11.2004.…”
