目的探究核磁共振成像(MRI)与颅脑CT在老年多发性脑梗死诊断中的应用价值。方法 70例老年多发性脑梗死患者,随机分为观察组和对照组,各35例。对照组实施CT检查,观察组实施MRI检查。比较两组患者脑梗死指标检测情况和脑梗死病灶检出部位。结果观察组病灶大小、数量、发病至检查时间、检查时间分别为(8.34±1.63)mm2、(1.89±0.66)个、(0.92±0.23)d、(10.15±1.36)min,优于对照组的(11.41±2.78)mm2、(2.62±0.98)个、(2.01±0.43)d、(18.93±2.65)min,差异有统计学意义(P<0.05);观察组额叶、顶叶、颞叶、小脑检出率分别为48.57%、40.00%、62.86%、74.29%,均高于对照组的25.71%、17.14%、5.71%、37.14%,差异有统计学意义(P<0.05);两组脑室旁、基底节区、丘脑检出率相比差异无统计学意义(P>0.05)。结论与CT检查相比,MRI在检查老年多发性脑梗死中准确率更高,在早期、多发性梗死灶、后颅凹梗死灶、较小病灶等方面检验具有明显的优势。
Objective To explore the value of magnetic resonance imaging (MRI) and brain CT in the diagnosis of senile multiple cerebral infarction. Methods Seventy patients with senile multiple cerebral infarction were randomly divided into observation group and control group, with 35 cases in each group. The control group performed CT examination and observation group performed MRI examination. Comparison of two groups of patients with cerebral infarction detection and detection of cerebral infarction lesions. Results The size and number of lesions in the observation group were (8.34 ± 1.63) mm2, (1.89 ± 0.66), (0.92 ± 0.23) and (10.15 ± 1.36) min respectively, which were significantly higher than those in the control group (11.41 ± 2.78) mm2, (2.62 ± 0.98), (2.01 ± 0.43) d and (18.93 ± 2.65) min respectively, with significant difference (P <0.05). The frontal lobe, parietal lobe, temporal lobe, The detection rates of cerebellum were 48.57%, 40.00%, 62.86% and 74.29%, respectively, which were significantly higher than that of the control group (25.71%, 17.14%, 5.71% and 37.14%, P <0.05) Parathyroid, basal ganglia, thalamus detection rate was no significant difference (P> 0.05). Conclusion Compared with CT examination, MRI is more accurate in examining elderly patients with multiple cerebral infarction. It has obvious advantages in the examination of early stage, multiple infarction, posterior cranial infarction and small lesions.
