目的:探讨18F-FDG显像联合CEA检测诊断结直肠癌术后复发的鉴别诊断价值。方法:采用18F-FDG双探头符合线路显像,同机图像融合,并检测CEA。结果:CEA阳性组18F-FDG PET/CT显像的灵敏度为93.3%(28/30),阳性预测值为96.6%(28/29),特异度为85.7%(6/7),阴性预测值为75.0%(6/8),准确性91.9%(34/37)。CEA阴性组18F-FDG PET/CT显像的灵敏度84.6%(11/13),阳性预测值57.9%(11/19),特异性为20%(2/10),阴性预测值50%(2/4),准确性97.3%(13/23)。结论:18F-FDG显像联合血肿瘤标志物检测能明显提高结直肠癌复发的检出率。
Objective: To investigate the differential diagnosis value of 18F-FDG imaging combined with CEA in the diagnosis of postoperative recurrence of colorectal cancer. Methods: 18F-FDG dual-head coincidence line imaging, the same machine image fusion, and detection of CEA. Results: The positive predictive value of 18F-FDG PET / CT in CEA positive group was 93.3% (28/30), the positive predictive value was 96.6% (28/29) and the specificity was 85.7% (6/7). The negative predictive value 75.0% (6/8), accuracy 91.9% (34/37). The sensitivity and specificity of 18F-FDG PET / CT imaging in CEA negative group were 84.6% (11/13), 57.9% (11/19), 20% (2/10), and 50% / 4), accuracy of 97.3% (13/23). Conclusion: The detection of 18F-FDG combined with hematological tumor markers can significantly improve the detection rate of recurrence of colorectal cancer.
