The aim of this retrospective study was to assess the significance of incidental focal colonic lesions on fluoro-2-deoxy-d-glucose positron emission tomography/computed tomography (FDG PET/CT) scans in patients undergoing staging for noncolorectal cancer.
Of the 110 patients in our PET/CT database, 10 were found to have abnormally high uptake of tracer in their large bowel.
Seven patients who underwent further endoscopic evaluation of these abnormalities had intermediate to high-risk adenomatous polyps.
Benign colonic polyps produce high-intensity focal FDG uptake in large bowel. Endoscopic evaluation is recommended before curative resectional surgery of the presenting cancer where appropriate.
这项回顾性研究的目的是评估在接受非结直肠癌分期检查的患者中，氟代脱氧葡萄糖正电子发射断层扫描/计算机断层扫描（FDG PET/CT）检查时偶然发现的局灶性结肠病变的意义。
在我们的PET/CT数据库中的110例患者中，有10例被发现其大肠内示踪剂摄取异常增高。
对这些异常进行进一步内镜评估的7例患者患有中至高危腺瘤性息肉。
良性结肠息肉在大肠内产生高强度局灶性FDG摄取。在适当时，建议在对现存癌症进行根治性切除手术前进行内镜评估。
