糖尿病患者颈动脉内中膜厚度及其背向散射积分的研究

目的研究糖尿病患者颈动脉内中膜厚度（IMT）及其背向散射积分（C-IBS）的变化。方法糖尿病患者和正常对照组各50人，分别测量颈动脉内中膜厚度及校正的背向散射积分（C—IBS）值，比较两者在各组中的变化及两者的关系。结果糖尿病患者颈动脉内中膜C—IBS和IMT均较正常对照组显著增高，糖尿病患者颈动脉内中膜C—IBS值属于纤维组织范围，正常对照组颈动脉内中膜C-IBS和IMT呈显著的正相关，糖尿病患者颈动脉内中膜C-IBS和IMT无明显相关。结论运用IBS技术能够早期发现糖尿病患者颈动脉病变的性质。

The study on IBS of carotid intima-media in diabetes patients

Objective To investigate the changes of intima-media thickness and IBS of carotid in diabetes patients.Methods IMT measurement and calibrated IBS(C-IBS)analysis were performed on fifty diabetes patients and fifty normal controls,the changes of IMT and C-IBS and the relation between them were analyzed in the two groups.Results Carotid intima-media C-IBS was significantly higher and IMT was significantly thicker in those with diabetes than in the controls.The carotid intima-media C-IBS in those with diabetes was in the range of fibrous tissue.C-IBS was positively correlatd to IMT in the controls,but no correlation between C-IBS and IMT was found in diabetes patients.Conclusion C-IBS can be a useful tool to detect a vascular change related to diabetes.
