摘要
目的分析宝石能谱CT对先天性血管病患者的诊断价值。方法选取我院收治的30例先天性心血管病患者,均行宝石能谱CT个体化扫描,与病理结果对照,观察其检查灵敏度、特异度与准确性,记录图像质量主观评分与客观评分、图像噪声、信躁比(SNR)、对比剂噪声比(CNR)。结果宝石能谱CT个体化扫描图像质量主观评分(4.78±0.14)分与客观评分(4.17±0.26)分、图像噪声(7.65±0.78)Hu、SNR(41.12±4.69)及CNR(36.04±2.95);宝石能谱CT个体化扫描诊断房缺动脉导管未闭灵敏度83.33%(5/6),特异度95.83%(23/24),准确性93.33%(28/30),Kappa值为0.79;室缺房缺灵敏度50.00%(1/2),特异度96.43%(27/28),准确性93.33%(28/30),Kappa值为0.46;房缺与室缺诊断准确性均为100%。结论宝石能谱CT个体化扫描图像质量较好,图像噪声小,具有较高准确性,为诊断先天性心血管病良好影像学方式。
Objective To analyze the diagnostic value of gemstone spectral CT in patients with congenital cardiovascular disease.Methods 30 patients with congenital cardiovascular disease admitted to the hospital underwent individualized scanning of gemstone spectral CT.The results were compared with pathological results.The sensitivity,specificity and accuracy of the examination were observed.Subjective scores and objective scores of image quality,image noise,ratio of signal to noise ratio (SNR),ratio of contrast agent to noise (CNR) were recorded.Results The individualized scanning of gemstone spectral CT showed the subjective scores [(4.78±0.14) points] and objective scores [(4.17±0.26) points] of the image quality,image noise [(7.65±0.78) Hu],SNR (41.12±4.69) and CNR (36.04±2.95).The sensitivity,specificity,accuracy and Kappa value for the diagnosis of atrial septal defect and arterial duct occlusion by individualized scanning of gemstone spectral CT were 83.33%(5/6),95.83%(23/24),93.33%(28/30) and 0.79,respectively.The above indexes for the diagnosis of ventricular septal defect combined with atrial septal defect were 50.00%(1/2),96.43%(27/28),93.33%(28/30) and 0.46.The diagnostic accuracy rates for ventricular septal defect and atrial septal defect are all 100%.Conclusion The individualized scanning of gemstone spectral CT has good image quality and low image noise,which has high accuracy.It is a good imaging method for diagnosing congenital cardiovascular disease.
