Use of high-resolution 3.0-T magnetic resonance imaging to characterize atherosclerotic plaques in patients with cerebral infarction

Objective: To analyze the relationship between TOAST classification of cerebral infarction after cerebral ischemia and traditional risk factors by high-resolution NMR. Methods: A total of 942 patients with cerebral infarction who were hospitalized in our hospital from January 2012 to October 2019 were enrolled. After performing brain magnetic resonance examination, they were classified according to magnetic resonance imaging, and the patient’s age was recorded. Clinical data such as gender and disease history, and routine examination of diabetes, blood lipids, etc., according to the results of the test, TOAST classification, comparison with magnetic resonance imaging classification results, and correlation analysis of risk factors affecting cerebral infarction. Results: The results of the study showed that 942 patients with posterior circulation ischemic cerebral infarction had aortic atherosclerosis (49.04%), small artery occlusion (39.49%), cardiogenic embolism (6.16%), and unexplained type. (5.20%), other reasons (0.11%). There was a significant correlation between DWI imaging characteristics and TOAST classification (χ = 397.785, P = 0.000). Cortical.cortical infarction, unilateral anterior circulation infarction, large perforating infarction, and anterior.posterior circulation infarction were associated with LAA type, and the difference was statistically significant (P < 0.05). Conclusion: The results of the study fully demonstrate that the characteristics of high-resolution NMR imaging are related to the TOAST classification of patients with cerebral infarction caused by posterior circulation ischemia. Traditional risk factors such as age, NIHSS score, coronary heart disease and atrial fibrillation have certain characteristics on DWI imaging. Impact. Therefore, patients with posterior circulation ischemic cerebral infarction need early high-resolution MRI and combined with traditional risk factors to choose treatment options to reduce the disability and mortality of patients.

Purpose: We analyzed and compared the imaging characteristics of the vessel wall of the middle cerebral artery (MCA) in symptomatic and asymptomatic patients using a 3.0-T high-resolution magnetic resonance imaging (HR-MRI) protocol, including a 3-dimensional T1-sampling perfection with application-optimized contrasts using different flip angle evolutions sequence. Methods: Fifty-three patients with atherosclerotic stenosis of the MCA underwent 3.0-T HR-MRI examinations. The characteristics of atherosclerotic plaques in 53 patients (28 symptomatic, 25 asymptomatic) were analyzed, including plaque distribution and signal intensity. Plaque burden (PB), stenosis degree, and the remodeling index were measured and compared between symptomatic and asymptomatic patients. Results: The PB of the symptomatic group was significantly higher than that of the asymptomatic group ( P = .006), and moderate−severe stenosis was more common ( P = .01). The remodeling index of the symptomatic group was also lower ( P = .015) and negative remodeling (NR) was more common ( P = .043). Binary logistic regression analysis showed that stenosis degree was a risk factor in symptomatic patients (odds ratio = 135, P = .023). Conclusion: There is a trend that some characteristics of plaques and vessels, including the moderate-severe stenosis, larger PB, and NR, were observed more frequently among patients with symptomatic atherosclerotic stenosis of the MCA than among asymptomatic patients.
