Abstract：Objective: To analyze the value of carotid magnetic resonance angiography (MRA) in predicting short-term acute cerebral infarction in patients with transient ischemic attack (TIA). Methods: A total of 150 TIA patients admitted to our hospital from January 2021 to June 2022 were selected and divided into a concurrent group (n=32) and a non-concurrent group (n=118) based on the incidence of acute cerebral infarction. The results of carotid MRA examinations were observed, the independent predictive indicators for concurrent ACI were screened through multivariate logistic regression analysis, and their individual and combined predictive value was assessed. Results: The proportion of severe stenosis, plaque hemorrhage, necrotic fat nuclei, fibrous cap rupture and other values in patients with atherosclerosis was higher than that in non-concurrent patients (P<0.05), the minimum lumen area was smaller than that in non-concurrent patients (P<0.05), and the maximum wall thickness was larger than that in non-concurrent patients (P<0.05). Multivariate analysis showed that plaque bleeding (OR=8.72, 95% CI: 2.34~32.48), fibrous cap rupture (OR=6.95, 95% CI: 1.89~25.61), and maximum wall thickness (OR=1.42, 95% CI: 1.05~1.92) were independent predictive factors for concurrent ACI. The sensitivity of the joint prediction model is 90.6%, and the specificity is 88.1%, higher than that of single indicator detection. Conclusion: In the detection of carotid MRA, plaque bleeding, fibrous cap rupture, and maximum wall thickness are independent predictive indicators for TIA complicated with ACI. The combined application can significantly improve the predictive efficiency and has important clinical significance.
