摘 要 目的:探究阿尔茨海默病患者海马代谢的磁共振波谱的分布规律以及特点,为临床诊断提供重要的参考依据。方法:采用对比实验方法,以20例阿尔茨海默病患者作为实验组患者,选取同期年龄性别等基本相似的20例健康人作为对照组,对两组研究对象的智力状况、认知能力等进行简单的评定,同时采用核磁共振波普成像检查技术和方法对两组研究对象的核磁波谱分布状况和规律进行对比和分析。结果:两组智力状况、认知能力、海马区核磁共振谱的各项指标存在显著差异(P<0.05)。结论:阿尔茨海默病患者海马区的图谱明显与健康研究对象有明显的差别,这临床诊断提供了有效的证据,具有重要的价值和意义。

ABSTRACT Objective: To explore the distribution and characteristics of magnetic resonance spectrum (MRS) of hippocampal metabolism in the patients with Alzheimers disease, and provide the important reference basis for the clinical diagnosis. Methods: A simple assessment of the intelligence and cognitive abilities in both of the experimental group (20 cases) and the control group (20 cases) was performed by a comparative experimental method. Meanwhile the distribution and regularity of MRS were compared and analyzed between the two groups by MRI. Results: There exited significant differences between the two groups in intelligence status, cognitive ability and hippocampal MRS (P<0.05). Conclusion: The atlas of the hippocampus in the patients with Alzheimers disease are obviously different from those of the healthy subjects, which can provide effective evidence for clinical diagnosis and is of great value and significance.

阿尔茨海默病是临床上常见的一种脑部病变性疾病,痴呆患者中约有60%~70%的患者会患有该种疾病,目前还没有一种有效的临床治疗方法对该疾病进行治疗[1-2]。因此,临床上对于该类疾病的有效控制方法是早期诊断和早期干预,以便及时采取措施控制病情的快速发展。已有的临床数据资料分析,患者出现各种临床症状的主要原因是大脑海马区相应的生化物质分布发生了很大的变化,由于物质分布的异常,致使患者表现出各種病态的临床症状。本研究选取健康人员和阿尔茨海默病患者作为研究对象,对比分析阿尔茨海默病患者海马区磁共振谱的特征与健康人员的差别,为临床诊断阿尔茨海默病提供重要的参考依据。……
