Abstract：Objective To explore the correlation between the measurement of brain area volume in patients with cerebral in-farction using magnetic resonance artificial intelligence brain segmentation software and the National Institutes of Health Stroke Scale(NIHSS)score.Methods 83 patients with cerebral infarction diagnosed in our hospital from August 2022 to August 2023 were randomly selected as the study subjects.According to the admission NIHSS score,they were divided into mild group of 18 cases(0～4 points),moderate group of 45 cases(5～15 points),and severe group of 20 cases(6～42 points).After ad-mission,1.43T MRI scanning of the head and artificial intelligence brain segmentation software were used to measure the volume of various brain regions,including the whole brain,temporal lobe,occipital lobe,frontal lobe,parietal lobe,cerebellum,and ventricles.The total infarct volume was calculated based on T2WI sequence.Results There were no differences of gender,age,body mass index,systolic and diastolic blood pressure,fasting blood glucose,and total cholesterol levels among the three groups of patients(P>0.05).There were no differences in the volume of the whole brain,occipital lobe,parietal lobe,cerebel-lum,and ventricles among the three groups(P>0.05).However,the volume of the temporal and frontal lobes in the moderate to severe group was significantly smaller than that in the mild group,and the total volume of infarction was significantly larger than that in the mild group(P<0.05).There was no significant difference between the moderate and severe groups(P>0.05).Spear-man test showed negative correlation between temporal,frontal lobe volume and NIHSS score,total infarct volume(P<0.05),while there was no correlation between total infarct volume and NIHSS score(P>0.05).Conclusion Magnetic resonance artifi-cial intelligence brain segmentation software can accurately locate and measure the volume of each brain area.The reduction of temporal and frontal lobe volume may be related to increase of NIHSS scores for admitted cerebral infarction patients,which is helpful for assessing the severity of the condition.
