血管钙化与透析患者的不良预后相关。它可以评估与计算机断层扫描，但简单的inoffice技术可以提供有用的信息。我们比较了一种简单的非侵入性技术与多探测器计算机断层扫描获得的慢性血液透析（HD）患者主动脉弓钙化体积（AoACV）的结果。入组的研究受试者为63例（32例男性和31例女性）维持性HD患者。在胸部平片上用AoAC评分（AoACS）半定量评估主动脉弓钙化。AoACV增加，平均值为6.6，范围为0%-36.5%。观察者内变异系数小于2.5%。主动脉弓钙化积分与AoACV高度相关（r=0.635，P < 0.001）。多元回归分析显示年龄（F值=12.62，P < 0.001）和脉压（F值=4.54，P=0.037）是AoACS的独立影响因素。总之，一个简单的测量AoACS可能是有用的inoffice成像选择治疗方案的HD患者。
Vascular calcification is associated with a poor prognosis in dialysis patients. It can be assessed with computed tomography but simple inoffice techniques may provide useful information. We compared the results obtained with a simple noninvasive technique with those obtained using multidetector computed tomography for aortic arch calcification volume (AoACV) in chronic hemodialysis (HD) patients. The enrolled study subjects were 63 (32 men and 31 women) maintenance HD patients. Calcification of the aortic arch was semiquantitatively estimated with a AoAC score (AoACS) on plain chest radiology. The AoACV was increased, with a mean value of 6.6 ranging from 0% to 36.5%. The coefficient of intraobserver variation was less than 2.5%. Aortic arch calcification score was highly correlated with AoACV (r=0.635, P < 0.001). Multiple regression analysis showed age (F value=12.62, P < 0.001) and pulse pressure (F value=4.54, P=0.037) to be significant independent determinants of AoACS. In conclusion, a simple measurement of AoACS may be useful for inoffice imaging to choose a therapeutic regimen in HD patients.
