摘要

目的：评估胸部CT平扫对贫血的诊断价值及其准确性。方法：采用GE LightSpeed 64层螺旋CT，回顾性分析111例胸部CT平扫图像，分析左、右心室腔、室间隔及主动脉腔CT值与血红蛋白浓度间的相关性，明确主动脉环征、室间隔高密度征与贫血的关系。结果：在整个人群中，左、右室及主动脉腔内血液CT值与血红蛋白浓度呈直线正相关（P＜0.05）。贫血组室间隔高密度征出现率为50%（22/44 例），主动脉环征出现率36.4%（16/44 例），正常组室间隔高密度征及主动脉环征出现率皆为6.0%（4/67 例），其差异有统计学意义（P＜0.05）。结论：利用多层螺旋CT胸部平扫判断贫血是可行的，心室及主动脉密度减低，主动脉环征、室间隔高密度征均可确定是否贫血，并可判断血红蛋白含量的大体范围。

Abstract

Objective: To determine whether CT Scan can be applied in diagnosing the presence or severity of anemia.Methods:Totally 111 patients were underwent GE LightSpeed 64 layer spiral CT.The correlation between the CT value in the left ventricular(LV) cavity

right ventricular(RV) cavity

interventricular septum and arotic lumens and the blood hemoglobin level was analyzed. The relationship among aortic ring sign

interventricular septum high

intensity sign and anemia was identified.Results：Positive correlation was observed between the aortic CT attenuation values and the hemoglobin levels in the whole study population(P＜0.05).The ratio of the interventricular septum high density sign in the anemia group was much higher than that in the control group(50%vs.6%

P＜0.05). The ratio of the aortic ring sign in the anemia group was much higher than that in the control group(36.4%vs.6%

P<0.05).Conclusion:Using unenhanced thoracic CT scans to evaluate the anemia is available.The sign of decreased ventricle and aortic lumens density

aortic ring sign and interventricular septum high density are helpful in roughly judging the presence or absence of anemia and determining the hemoglobin level.
