| 摘 要： | 目的探讨18F-FDP PET-CT对结直肠癌术前TNM分期的价值。方法回顾总结术前行PET-CT的30例(33例次)结直肠癌患者,将PET-CT结果与术后手术病理分期结果对比分析。结果检测直肠癌原发灶灵敏度为96.97%;SUVmax为12.26±5.85(5.3128.32)。N分期的灵敏度为88.23%;特异度为69.23%,共提示转移性淋巴结69枚,SUVmax为2.526±2.074(0.2728.32)。N分期的灵敏度为88.23%;特异度为69.23%,共提示转移性淋巴结69枚,SUVmax为2.526±2.074(0.2711.70),淋巴结总检出率为75%,一致率为80%。PET-CT诊断远处转移灶的灵敏度100%、特异度100%、准确性为100%,SUVmax值6.15±3.63(1.8311.70),淋巴结总检出率为75%,一致率为80%。PET-CT诊断远处转移灶的灵敏度100%、特异度100%、准确性为100%,SUVmax值6.15±3.63(1.8315.84)。结论 18F-FDP PET-CT与术后病理比较对结直肠癌进行T分期较为困难,但对于N、M分期有较好的一致性。

| Abstract: | Objective To explore the value of clinical staging of colorectal carcinoma with 18F-FDG PET-CT.Methods Clinical data of 30 cases of colorectal carcinoma collected, including PET-CT and pathology, were analyzed retrospectively.Results In 30 patients, the sensitivity of the diagnosis of the primary lesion detection was 96.97%; The maximum standardized uptake value（SUVmax） within the lesion were 12.26±5.85; While the accuracy in diagnosis in distant metastasis was 100%; The SUVmax within the lesion were 6.15±3.63; As to diagnosis in N staging,the accuracy was 80%, with 88.23% sensitivity and 69.23% specificity.Conclusion 18F-FDG PET-CT imaging is useful in the clinical N staging and M staging of colorectal carcinoma. |
