摘要
目的探讨^(18)氟-氟代脱氧葡萄糖正电子发射计算机断层显像/电子计算机X射线扫描技术(^(18)F-FDG PET/CT)显像在结直肠癌术后随访中的应用价值。方法回顾性分析2010年4月至2012年5月在我院行结直肠癌术的50例患者的临床资料,收集并分析患者的MRI、CT或超声等影像学资料及^(18)F-FDG PET/CT显像结果。结果随访过程中,41例患者伴肿瘤复发、转移症状,9例无复发、无转移,经PET/CT检测确诊阳性30例,阴性20例,其灵敏度为93.54%,特异度为94.73%,准确度94.00%;增强CT诊断阳性24例,阴性26例,其灵敏度为58.06%,特异度为47.37%,准确度为56.00%;^(18)F-FDG PET/CT检查的灵敏度、特异度、准确度均显著高于增强CT检查,差异有统计学意义(P<0.05)。结论 ^(18)F-FDG PET/CT显像在结直肠癌术后随访中有较高的应用价值,能够反映术后肿瘤复发、转移情况,灵敏度、特异度、准确度均较高。
Objective To explore the application value of 18F-deoxyglucose positron emission tomography / computer tomography （18F-FDG PET/CT） imaging in postoperative follow-up of colorectal cancer. Methods The clinical data of 50 cases of patients with colorectal cancer undergoing operation in our hospital from April 2010 to May 2012 were analyzed retrospectively. The imaging data of MRI, CT or ultrasound and imaging findings of 18F-FDG PET/CT were collected and analyzed. Results During the follow-up, 41 cases of patients had tumor recurrence and metastasis, and other 9 cases did not. PET/CT confirmed that there were 30 positive cases and 20 negative cases, and its sensitivity, specificity and accuracy were respectively 93.54%, 94.73% and 94.00%. Enhanced CT confirmed that there were 24 positive cases and 26 negative cases, and its sensitivity, specificity and accuracy were respectively 58.06%, 47.37% and 56.00%. The sensitivity, specificity and accuracy of 18F-FDG PET/CT were significantly higher than those of enhanced CT （P〈0.05）. Conclusions 18F-FDG PET/CT imaging has higher application value in postoperative follow-up of colorectal cancer, can reflect the recurrence and metastasis of turnors after operation, and has higher sensitivity, specificity and accuracy.
