BackgroundMRI and fluorine 18–labeled sodium fluoride (18F-NaF) PET can be used to identify features of plaque instability, rupture, and disease activity, but large studies have not been performed.PurposeTo evaluate the association between18F-NaF activity and culprit carotid plaque in acute neurovascular syndrome.Materials and MethodsIn this prospective observational cohort study (October 2017 to January 2020), participants underwent18F-NaF PET/MRI. An experienced clinician determined the culprit carotid artery based on symptoms and record review.18F-NaF uptake was quantified using standardized uptake values and tissue-to-background ratios. Statistical significance was assessed with the Welch, χ2, Wilcoxon, or Fisher test. Multivariable models were used to evaluate the relationship between the imaging markers and the culprit versus nonculprit vessel.ResultsA total of 110 participants were evaluated (mean age, 68 years ± 10 [SD]; 70 men and 40 women). Of the 110, 34 (32%) had prior cerebrovascular disease, and 26 (24%) presented with amaurosis fugax, 54 (49%) with transient ischemic attack, and 30 (27%) with stroke. Compared with nonculprit carotids, culprit carotids had greater stenoses (≥50% stenosis: 30% vs 15% [P= .02]; ≥70% stenosis: 25% vs 4.5% [P< .001]) and had increased prevalence of MRI-derived adverse plaque features, including intraplaque hemorrhage (42% vs 23%;P= .004), necrotic core (36% vs 18%;P= .004), thrombus (7.3% vs 0%;P= .01), ulceration (18% vs 3.6%;P= .001), and higher18F-NaF uptake (maximum tissue-to-background ratio, 1.38 [IQR, 1.12–1.82] vs 1.26 [IQR, 0.99–1.66], respectively;P= .04). Higher18F-NaF uptake was positively associated with necrosis, intraplaque hemorrhage, ulceration, and calcification and inversely associated with fibrosis (P= .04 toP< .001). In multivariable analysis, carotid stenosis at or over 70% (odds ratio, 5.72 [95% CI: 2.2, 18]) and MRI-derived adverse plaque characteristics (odds ratio, 2.16 [95% CI: 1.2, 3.9]) were both associated with the culprit versus nonculprit carotid vessel.ConclusionFluorine 18–labeled sodium fluoride PET/MRI characteristics were associated with the culprit carotid vessel in study participants with acute neurovascular syndrome.Clinical trial registration no.
