【摘要】 【目的】评估三种影像学检查方法对诊断缩窄性心包炎的诊断价值。【方法】对比分析59例X线胸片、CT、B超检查缩窄性心包炎的心脏增大、房室增大、心包增厚、心包钙化、肺淤血、心包积液、上下腔静脉增宽、房室功能受限、室间隔变形和矛盾运动方面的差异,其中40例与手术结果进行了比较。【结果】心脏增大、心包增厚、心包钙化、心包积液的CT检查结果优于X线胸片和B超;观察肺淤血以X线胸片最佳;而心脏房室增大、房室功能受限、室间隔变形和矛盾运动的观察B超具有明显优势;上下腔静脉增宽B超也稍优于CT。与手术结果比较:CT阳性率为95.0%,B超阳性率为85.0%,X线胸片阳性率为67.5%。【结论】缩窄性心包炎的影像诊断应以CT为主,如辅以B超和X线检查,则诊断准确率可以到98.31%。更多还原

【Abstract】 【Objective】To evaluate three kinds of imagings in the diagnosis of constrictive pericarditis.【Method】The cardiac、atrioventricular enlargement、pericardial thickening、 calcification、lung congestion、pericardial hydrops、widened superior and inferior vena cava,limited atrioventricular function、ventricular septal deformity and paradoxical motion in 59 chest X-ray films、CT、B-ultrasonic imagings were examined and compared with the result of 40 cases with surgery.【Result】The manifestations of CT in cardiac enlargement、pericardial thickening、calcification、cardial hydrops were superior to X-ray film and B-ultrasound,but X-ray film was best in observing lung congestion,nevertheless ultrasound showed more advantage in observation of atrioventricular enlargement,atrioventricular function limitation、intraventricular septum deformity and paradoxical motion as well as superior and inferior vena cava widening.To compare with operation result:CT positive rate was 95.0%,ultrasound 85.0%,X-ray film 67.5%.【Conclusion】CT examination is the main method in diagnosing constrictive pericarditis,if associated with ultrasound and X-ray film,the accurate diagnosis rate can reach 98.31%.更多还原
