In 21 patients with clinically suspected recurrent rectal cancer showing a mass in the pelvic CT scan, Positron Emission Tomography (PET) was performed to measure metabolic rate of the mass. In 13 of the 21 patients an increased F-18-Fluorodeoxyglucose (FDG) uptake in the suspect tissue could be found. All of these patients were proven to suffer recurrent cancer by biopsy. 8 of the 21 patients showed normal uptake and 7 of them revealed scar tissue by histology. Therefore PET could distinguish clearly between cancer and scar tissue.
在21例临床怀疑为复发性直肠癌且盆腔CT扫描显示有肿块的患者中,进行了正电子发射断层扫描(PET)以测量肿块的代谢率。在这21例患者中,有13例在可疑组织中发现F-18-氟脱氧葡萄糖(FDG)摄取增加。所有这些患者经活检均被证实患有复发性癌症。21例患者中有8例摄取正常,其中7例经组织学检查显示为瘢痕组织。因此,PET能够清晰地区分癌症和瘢痕组织。
