摘要:

目的 研究阿爾茨海默病患者與對(duì)照組胼胝體和扣帶回部位紋理參數(shù)的特點(diǎn),并測(cè)試紋理參數(shù)和AD(Alzheimer,s diease,阿爾茨海默病)病程進(jìn)展的相關(guān)性。方法 采用灰度共生矩陣的紋理分析方法對(duì)患者和健康對(duì)照組MR圖像上胼胝體和扣帶回部位提取紋理參數(shù),并比較紋理參數(shù)與MMSE(minimental state examination,簡(jiǎn)易精神狀態(tài)檢查)評(píng)分的相關(guān)性。結(jié)果 AD患者和對(duì)照組胼胝體及扣帶回部位的紋理參數(shù)存在顯著性差異,扣帶回部位的紋理參數(shù)和MMSE評(píng)分顯著相關(guān)。結(jié)論 本研究表明紋理分析可以量化描述AD患者胼胝體和扣帶回的病理變化,可能為早期診斷提供幫助。

Objective  To study the characteristic of the texture features in corpus callosum and cingulate of Alzheimer’s disease(AD) and normal control group,and test the relationship between texture features and AD disease progression. Methods  Corpus callosum and cingulate were selected as regions of interests (ROIs). Texture features were extracted from gray level cooccurrence matrix in ROIs,and the correlation between texture features and MMSE scores were calculated. Results  Texture features in corpus callosum and cingulate were significantly different between AD and normal controls group and texture features in cingulate was significantly correlated with MMSE scores.  Conclusion  The study demonstrated that texture analysis was able to quantify the pathological changes of corpus callosum and cingulate in MR image of AD patients and may aid in early diagnosis of AD.
