老年糖尿病临床与脑CT、MRI检查对比分析

A comparative analysis between clinical and brain CT,MRI examination in elderly diabetes

目的探讨脑ＭＲＩ、ＣＴ在老年糖尿病并发脑血管病早期诊断中的价值。方法本文对５２例老年２型糖尿病患者同时进行脑ＭＲＩ与ＣＴ的对比检查。结果（１）老年糖尿病患者的脑ＭＲＩ阳性检出者为４５例（８６５％），而脑ＣＴ阳性检出者为２９例（５５８％）（Ｐ＜００１）；（２）糖尿病病程在１０年以内患者中脑ＭＲＩ阳性率（８０８％）明显高于ＣＴ阳性率（３４６％）（Ｐ＜００１），但当糖尿病病程在１０年和１０年以上患者中脑ＭＲＩ阳性率（９２３％）与ＣＴ阳性率（７６９％）相比（Ｐ＞００５），无统计学显著差异；（３）糖尿病脑ＭＲＩ阳性组并发高血压和高脂血症者均高于糖尿病ＭＲＩ阴性组（Ｐ＜００５～００１）。结论脑ＭＲＩ是老年糖尿病脑血管病的一种早期敏感的诊断方法。

Objective To study the value of CT and MRI as early diagnostic methods in cerebrovascular disease of elderly diabetes. Methods Brain CT and MRI in 52 elderly cases type 2 diabetes were performed. Results (1)The positive findings of brain MRI in elderly diabetes were found in 45 cases(86 5%),while the positive findings of brain CT found in 29 cases(55 8%), P <0 01;(2)The positive rate of brain MRI in diabetes with duration less than 10 years was 80 8%.It is significantly higher than that in CT scan(34 6%), P <0 01.But there is no statistical difference in the comparison between the positive rate of brain MRI(92 3%)and CT(76 8%)in diabetes with duration over 10 years( P >0 05);(3)The positive group of brain MRI in diabetes with hypertension and hyperlipidemia was higher than those in the negative group( P <0 05～0 01). Conclusions The brain MRI is a sensitive early diagnostic method in cerebrovascular disease of elderly diabetes.
