Object: Correlation between some indices on pyramidal tract magnetic resonance in predicting motor function recovery in patients with supratentorial cerebral infarction. Method: Cross-sectional description with longitudinal follow-up includes 31 patients with supratentorial cerebral infarction within seven days and had an MRI at Bach Mai Hospital from January 2023 to December 2023. Result: The proportion of male patients with ischemic stroke predominated (61,3%). Hemiplegia was the most common symptom of ischemic stroke which damaged the path of the corticospinal tract. At three months after the stroke, no patient had severe NIHSS score ; the percentage of patients with mild and moderate NIHSS score was 61,3% and 38,7%, respectively. According to mRS, 25 patients (80,6%) recovered well after three months. The patient group, who had the axons did not go through the infarct lesion, had higher at rate of better motor function recovery after three months than the other groups who had the axons go through partly or completely inside the infarction lesion (respective rates were 64,5% and 16,1%); p<0,05. FA index of the axons in the infarct side of the poor recovery group was smaller than the good recovery group, p<0.05. Conclusion: The axonal signal, location versus the infarct lesion, and FA index of the axons in the infarct side are the factors that significantly predictive of motor recovery after three months in ischemic stroke patients.
