| 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. |
