目的 探讨联合应用CT和正电子发射计算机断层成像术(PET-CT)对结直肠黏液腺癌与非黏液腺癌的鉴别诊断价值.方法 回顾性分析2010年1月至2012年12月间中山大学附属第一医院收治、且接受CT和PET-CT检查的37例结直肠黏液腺癌与50例结直肠非黏液腺癌患者的临床和影像学资料.比较两者在CT和PET-CT表现上的差异.结果 CT检查示,在肿瘤实质的平扫密度、增强后密度和强化程度上,黏液腺癌组明显低于非黏液腺癌组,差异具有统计学意义(均P＜0.01);肿瘤低密度区的强化程度、低密度区面积占总病灶面积的比例、淋巴结转移及远处转移比例,黏液腺癌组均明显高于非黏液腺癌组(均P＜0.05).PET-CT检查示,黏液腺癌组的最大SUV值明显小于非黏液性腺癌组[(8.64±4.34) Bq/L比(12.38±5.96) Bq/L,P=0.015].结论 联合PET-CT与传统CT两种检查手段,可对结直肠黏液腺癌与非黏液腺癌进行有效的鉴别诊断.
目的 探討聯閤應用CT和正電子髮射計算機斷層成像術(PET-CT)對結直腸黏液腺癌與非黏液腺癌的鑒彆診斷價值.方法 迴顧性分析2010年1月至2012年12月間中山大學附屬第一醫院收治、且接受CT和PET-CT檢查的37例結直腸黏液腺癌與50例結直腸非黏液腺癌患者的臨床和影像學資料.比較兩者在CT和PET-CT錶現上的差異.結果 CT檢查示,在腫瘤實質的平掃密度、增彊後密度和彊化程度上,黏液腺癌組明顯低于非黏液腺癌組,差異具有統計學意義(均P＜0.01);腫瘤低密度區的彊化程度、低密度區麵積佔總病竈麵積的比例、淋巴結轉移及遠處轉移比例,黏液腺癌組均明顯高于非黏液腺癌組(均P＜0.05).PET-CT檢查示,黏液腺癌組的最大SUV值明顯小于非黏液性腺癌組[(8.64±4.34) Bq/L比(12.38±5.96) Bq/L,P=0.015].結論 聯閤PET-CT與傳統CT兩種檢查手段,可對結直腸黏液腺癌與非黏液腺癌進行有效的鑒彆診斷.

Objective To explore the value of comprehensive application of CT and PET/CT in differential diagnosing mucinous and non-mucinous colorectal adenocarcinoma.Methods CT and PET/CT image data of 37 patients with mucinous adenocarcinoma and 50 patients with non-mucinous adenocarcinoma confirmed by pathology in our hospital from January 2010 to December 2012 were analyzed retrospectively.Differences of image were compared between two methods.Results On CT,lesion density of pre-contrast,pro-contrast phase and enhancement degree were significantly lower in mucinous adenocarcinoma than those in non-mucinous adenocarcinoma (all P＜0.01).Enhancement degree of hypointense area,hypointense area proportion of total lesion,and lymphatic or distant metastasis ratio were significantly higher in mucinous adenocarcinoma than those in non-mucinous adenocarcinoma (all P＜0.05).On PET/CT,maximal SUV value of mucinous adenocarcinoma was significantly lower as compared to non-mucinous adenocarcinoma [(8.64±4.34) Bq/L vs.(12.38±5.96) Bq/L,P=0.015].Conclusions CT combined with PET/CT provides better valuable information in differential diagnosing between mucinous and non-mucinous colorectal adenocarcinoma and clinical practice.
