摘要 目的:探讨18F-FDGPET联合CT增强扫描在肝脏原发性肿瘤诊断中的临床价值。方法:选取经穿刺活检组织检查或手术病理检查证实的肝脏原发性肿瘤16例,先行全身18F-FDGPET显像后再行肝脏CT三期增强扫描,将所得结论与病理结果进行对比评价。结果:18F-FDGPET联合CT增强扫描诊断肝脏原发性肿瘤的阳性率为93.7%,单PET显像阳性率为62.5%,单CT增强扫描阳性率为81.2%。结论:PET显像联合CT增强扫描较单独PET显像或CT增强扫描对肝脏原发性肿瘤诊断的敏感性及准确性均有明显的提高,因此PET显像联合CT增强扫描在肝脏原发性肿瘤的诊断中有较高的临床价值。 Objective: To evaluate the clinical value of ^18F-FDG PET combined with eontrast-enhanced CT scan in the diagnosis of the primary tumors of the liver. Methods: 16 eases proved surgically and pathologically were examined with PET and then subjacted to CT with third-phase contrast-enhanced scan, and retrospectively analyzed. Results:The positive rate of ^18F-FDG PET combined with eontrast-enhanced CT scan in diagnosis of the primary tumors of the liver was 93.7%, whereas as the positive rate of FDG scan was 62.5% andCT with third-phase enhanced-contrast scan was 81.2%. Conclusion: PET combined with contrast-enhanced CT scan has more sensitivity and accuracy, than PET or CT contrast-enhanced scan. So, the combination of PET with CT has higher clinical value in the diagnosis of the primary tumors of the liver.
