摘要
目的通过对比分析经济型PET/CT与双源CT异机融合的图像质量,探讨异机融合的临床应用价值。方法对29例可疑肿瘤或肿瘤复发转移患者行经济型PET/CT的PET与双源CT图像融合,并与同机融合图像质量进行对比分析。结果两种方法均检出原发灶和转移灶共46个,异机融合图像质量优于同机融合(χ2=14.743,P<0.001)。结论双源CT与经济型PET/CT异机融合,方便实用,优势互补,可提高图像质量,对临床诊断和治疗肿瘤有重要价值。
Objective To explore the value of fusion of coincidence PET/CT image and dual source CT image in comparison of fused imaging quality.Methods Integration of coincidence PET/CT PET images with dual source CT images was performed in 29 cases with suspected tumor or tumor recurrence or metastasis,and the image quality was compared with that of PET/CT in fused images.Results Forty-six primary or metastic tumors were detected by both methods.The image quality in fused imaging of stand-alone coincidence PET/CT with dual source CT was better than that of coincidence PET/CT in fused images（χ2=14.743,P〈0.001）.Conclusion The integration of stand-alone coincidence PET/CT and dual source CT is convenient and practical,having complementary advantages,which may improve image quality and help clinical diagnosis and treatment of tumors.
