糖尿病患者颈动脉内中膜厚度及其背向散射积分的研究

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

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。

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 eorrelatd 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.
