目的探讨CT、磁共振成像(MRI)两种方法哪种更适合对急性脑梗死患者进行早期诊断。方法 97例急性脑梗死患者均使用CT与MRI检查方法进行检测,以MRI诊断结果为研究组,以CT诊断结果为对照组,并与最终诊断结果进行对照,观察两组检测效果。结果最终检测出病灶数259个,其中,皮质梗死灶70个,放射冠梗死灶50个,基底节区梗死灶60个,小脑梗死灶65个,脑干梗死灶14个;研究组与最终结果相符病灶数为234个,其中,皮质梗死灶64个,放射冠梗死灶43个,基底节区梗死灶52个,小脑梗死灶61个,脑干梗死灶14个;对照组与最终结果相符病灶数为128个,其中,皮质梗死灶42个,放射冠梗死灶21个,基底节区梗死灶31个,小脑梗死灶24个,脑干梗死灶10个;两组不同部位梗死灶检出数量比较,差异具有统计学意义(P<0.05)。研究组脑梗死总检出率为81.44%,明显高于对照组的48.45%,差异具有统计学意义(P<0.05)。97例患者中发病12 h内65例,发病12~24 h15例,发病24 h以上17例;研究组发病12 h内检出62例,发病12~24 h检出10例,发病24 h以上检出7例;对照组发病12 h内检出31例,发病12~24 h检出14例,发病24 h以上检出2例;两组不同发病时间脑梗死检出情况比较,差异具有统计学意义(P<0.05)。分析发现使用MRI与CT对发病后12 h内的急性脑梗死患者进行检查效果最好,随着发病后时间的逐渐增加,其检测的效果也逐渐减弱。结论使用MRI的早期诊断结果更为准确,此技术对急性脑梗死的早期诊断有着极为重要的意义,并可联合CT对急性脑梗死患者进行早期诊断,值得推广。
Objective To investigate which CT and magnetic resonance imaging (MRI) methods are more suitable for early diagnosis of patients with acute cerebral infarction. Methods Ninety-seven patients with acute cerebral infarction were examined by CT and MRI. The results of MRI diagnosis were taken as the research group, the CT diagnosis was used as the control group, and the results were compared with the final diagnosis. The detection results of the two groups were observed. As a result, 259 lesions were detected, including 70 cortical infarcts, 50 irradiation crown infarcts, 60 basal ganglia infarcts, 65 cerebellar infarcts and 14 brainstem infarcts. The study group and the final results The number of matched lesions was 234, of which 64 were cortical infarcts, 43 were irradiated crown infarcts, 52 were basal ganglia infarcts, 61 were cerebellar infarcts and 14 were stem infarcts. The control group was consistent with the final result There were 128 cortical infarcts, including 21 cortical infarcts, 31 infarcted lesions, 31 basal ganglia infarcts, 24 cerebellar infarcts and 10 brainstem infarcts. The difference was statistically significant (P <0.05). The total detection rate of cerebral infarction in the study group was 81.44%, which was significantly higher than that in the control group (48.45%), the difference was statistically significant (P <0.05). Among the 97 patients, 65 cases were within 12 hours of onset, 15 cases were from 12 to 24 hours and 17 cases were more than 24 hours after onset. In the study group, 62 cases were detected within 12 hours of onset and 10 cases were detected within 12 to 24 hours of onset. In the control group, 31 cases were detected within 12 hours of onset, 14 cases were detected within 12-24 hours after onset and 2 cases were detected more than 24 hours after onset. The differences between the two groups were statistically significant Significance (P <0.05). Analysis found that the use of MRI and CT within 12 h after onset of acute cerebral infarction in patients with the best examination, with the onset of time gradually increased, the effect of its test has gradually weakened. Conclusion The results of early diagnosis using MRI are more accurate. This technique is very important for the early diagnosis of acute cerebral infarction. It can be used in the early diagnosis of patients with acute cerebral infarction with CT, which is worth to be popularized.
