目的：评价阅砸双能量减影技术检测维持性血液透析(MHD)患者主动脉钙化的敏感性。方法抽取我院47例主动脉MSCT扫描钙化呈阳性且MSCT结果钙化严重程度为1~3级的MHD患者，再行阅砸双能量减影技术侧位胸片、侧位腹平检查。然后把图像分为两组院A组仅有阅砸标准图像，B组为阅砸标准图像和软组织影像院两组诊断医师分别对两组图像盲法阅片。分析两组结果有无差异。结果 A组94幅图像中57幅为阳性，阳性率为60.6%；B组94幅图像中76幅为阳性，阳性率为76.8%。结论在检测维持性血液透析(MHD)患者主动脉钙化的敏感性上阅砸双能量减影技术所得图像优于普通阅砸标准图像。

Objective To evaluate the sensitivity DR dual-energy subtraction (DES) in the diagnosis of aorta calcification in maintenance hemodialysis (MHD)patients. Methods 48 patients with the severity of aorta calcification by MSCT was graded from score 1 to 3 underwent DR dual-energy subtraction of lateral chest and lateral abdomen in our hospital. And then the results wil be divided into two groups:group A is DR images;group A is DR images and DES soft tissue images. Two grounps radiologists independent analyzed the results . Results The calcification rate of aorta was 60.6%in grounp A; The calcification rate of aorta was 76.8% in grounp B. Conclusion DR dual-energy subtraction technifque is superior to regular DR images in show aorta calcification in maintenance hemodialysis(MHD)patients.
