“…In our study, the prevalence of mild to moderate symptomatic carotid stenosis tend to be higher in IPH positive than negative group, although the difference was not significant when analyzing except occlusion cases. One previous study showed that the overall carotid stenosis evaluated by TOF MRA was similar between the IPH positive and negative groups (41.0% vs 44.6%, p = 0.649) [11]. This study enrolled patients with both symptomatic and asymptomatic carotid diseases.…”

Objective Carotid intraplaque hemorrhage (IPH) is a well-known risk indicator of thromboembolism, but it is not easy to rapidly detect IPH in acute symptomatic carotid disease. The aim of this study was to assess the utility of time-of-flight (TOF) magnetic resonance angiography (MRA) in the detection of IPH and evaluate the degree of stenosis and stroke patterns in patients with acute symptomatic carotid disease. Methods We retrospectively identified consecutive patients with acute symptomatic carotid disease who were admitted within 12 h after stroke onset. Fifty-nine patients underwent TOF MRA at admission and were categorized according to the presence or absence of intraplaque high signal intensity (HSI). The severity of carotid stenosis and diffusion-weighted magnetic resonance imaging lesion patterns were evaluated. Results Intraplaque HSI was detected in 28.8% of the enrolled patients (17/59). Mild-to-moderate symptomatic carotid stenosis was more frequent in the intraplaque HSI-positive group (70.6%) than in the intraplaque HSI-negative group (42.8%) (p = 0.015). The patients with intraplaque HSI more frequently exhibited a disseminated small infarction pattern (76.5% in the intraplaque HSI-positive group, 47.6% in the-negative group), and did not exhibit a border-zone infarction pattern (0% in the positive group, 16.7% in the negative group).
