摘要
目的:探讨诊断性CT的扫描在18F-FDG PET/CT在肿瘤显像中的临床应用价值。方法:回顾性总结2005年10月~2007年7月的28例肿瘤患者(男性29例,女性19例,平均年龄56±10.5岁资料。所有患者均先行PET/CT显像后,根据PET/CT显像结果的不同,行诊断性CT(增强CT)检查。按PET显像后的不同结果分为3组,组1入选18例,PET/CT显像明确有肿瘤病灶,术前临床要求提供准确的肿瘤供血血管及与临近组织的关系。组2入选15例,为PET/CT显像阴性。组3入选15例患者,PET/CT显像阳性,但不能定性。结果:①组1的18例患者通过诊断性CT的CTA检查,全部明确了病灶的血供及其与周围组织的关系。②组2及组3的30例PET表现阴性或阳性患者的诊断问题通过CT的增强扫描均得到确定或更正。结论:诊断性CT扫描的应用可以弥补常规PET/CT检查中的某些不足,达到优势互补作用。
Objective： To investigate the clinical value of diagnostic CT in ^18F - FDG PET/CT Imaging. Methods：We analysis retrospectively the data of PET/CT scan and diagnostic CT in 48 patients （29 males, 19 females, average age of 56 ±10.5, accumulated from Oct. 2005 to July 2007） who underwent PET/CT and diagnostic CT（Enhance CT）, All patients was divided into 3 groups according to different image of PET/CT. 18 cases who were found tumor by PET/CT in groupl, diagnostic CT supplied precise blood-supply blood vessel and near tissue relationship about tumor for clinical require; 15 cases who PET/CT imaging were negative in group 2; 15 patients were PET/CT imaging positive, but can not decide nature were in group 3; SPN were found by PET/CT in 20 patients of group 4. Results： ①All of patients in group 1 dentified blood - supply blood vessel of tumor and relationship between tumor and near tissue by diagnostic CT. ②Diagnostic conclusion of fifteen patients who already finished ^18F - FDG PET/CT Imaging was make sure or correct by diagnostic CT scan in group 2 and 3, Conclusions ：Application of diagnostic CT can make up some shortage of routine PET/CT.
