Objective Lower extremity blood vascular lesion is the main reason of mutilation caused by diabetes.We discuss the risk factors of lower extremity arteries of diabetes and try to find the morphologic characteristics of diabetic peripheral blood vascular lesions,thus to find the early diagnosis method.Methods Totally 172 cases of diabetic patients who were hospitalized in our hospital were given lower extremity ultrasonic examination,while 60 cases of meantime in patients were as control.IMT(internal membrane thickening),incidence of plaque,stenosis occlusion and hemodynamic index were compared between the two groups.Results The incidence of lower extremity atherosclerotic plaque,arterial stenosis and obliteration of diabetes is apparently higher than that of control group.The incidence of atherosclerotic plaque was mainly involved in femoral artery.While the incidence of stenosis and obliteration were mainly involved in the distal arteries below popliteal artery,especially,anterior tibial artery.Conclusion Color Doppler flow imaging is an important clinical examination wethod for the early diagnosis,prevention and treatment.

腹膜后肿物的来源和种类繁多,且为恶性较多,早发现、早诊断、早治疗对其预后起着重要的作用.二维超声显像及彩色多普勒可显示腹膜后肌肉、实质脏器及血管,将这些器官及间隙的占位征象加以显示,观察其囊性、实性及混合性肿物的形态特点与周围组织器官的关系,所以超声显像可增高腹膜后肿物检出率,现对72例腹膜后肿物患者超声图像进行分析.

输尿管结石是急腹症中的常见疾病之一,结石的部位50%～60%以上位于输尿管下段[1].输尿管下段结石因肠道气体和腹壁脂肪后方衰减的干扰,以及膀胱过度充盈所引起的后方增强伪像,容易误诊;腔内超声使探头更贴近病灶可近距离扫查,获得高清晰度的声像图,避免了各种因素的干扰,经临床应用,提高了诊断准确率.
