Why the study?
Is increased pulsatility index associated with intracranial arterial calcification in patients with acute ischemic stroke or transient ischemic attack?
Is increased pulsatility index associated with intracranial arterial calcification in patients with acute ischemic stroke or transient ischemic attack?
Increased pulsatility index is independently associated with the severity of intracranial arterial calcification, suggesting that calcification-related vascular resistance contributes to PI elevation.
No takes yet. Share an insight, caveat, or question.
PI may mark calcification-related resistance in stroke/TIA; extends cross-sectional links but leaves causality and practice change open.
Park et al. (2012) studied this question.
