四种影像学检查在消化系统肿瘤术后复发转移中的临床应用及评价

Study and evaluation of clinical application of four imaging devices in the recurrent or metastatic tumor of digestive system

目的:探讨符合线路显像、B超、CT和MRI在消化系统肿瘤术后复发转移中的临床应用价值并给以评价。方法:对35例临床怀疑复发转移的消化系统肿瘤术后患者行18F-脱氧葡萄糖符合线路显像、B超、CT和MRI检查,计算其诊断准确性、灵敏度、特异性,并与再次手术的病理诊断或综合各项检查结果和(或)随访证实结果分别做比较,经一致性检验,计算Kappa值。结果:符合线路显像、B超、CT和MRI检查与最后诊断间的Kappa值分别为0.785,0.40,0.449,0.80。结论:18F-脱氧葡萄糖符合线路显像对消化系统肿瘤术后复发转移的诊断与最后诊断间有较高的一致性,其诊断准确性明显高于B超、CT,灵敏度明显高于B超,有较高的临床应用价值,但应合理掌握。

Objective To discuss the clinical value of ^18F-FDG SPECT/PET, UB, CT and MRI in the diagnosis of recurrent or metastatic tumor of digestive system. Methods Thirty-five cases of postoperative patients with tumor of digestive system were checked with^18F-FDG SPECT/PET, UB, CT and MRI respectively. The results were analyzed by calculating its accuracy, sensitivity, specificity and also analyzed by SPSS 12.0 software compared with the ultimate diagnosis. Results The value of Kappa of ^18F-FDG SPECT/PET, UB, CT and MRI were 0. 785, 0. 40, 0. 449, 0. 80, respectively. Conclusion There is a good agreement with the ultimate diagnosis and ^18F-FDG SPECT/ PET. ^18F-FDG SPECT/PET has a high clinical value in the diagnosis of recurrent or metastatic tumor of digestive system, but it should be used rationally.
