- W1567006800 abstract "目的：评价乳腺癌灶的大小，乳腺组织密度、年龄、绝经状态对18F-脱氧葡萄糖（FDG）PET／CT标准摄取值的影响。方法：对27例临床疑单侧原发性乳腺癌患者（13例绝经前期和14例绝经后期）行^18F—FDGPET／CT显像。应用ROI技术行半定量方法测得癌灶的SUVmax，并应用图像处理软件镜像技术勾画对侧正常组织的SUVmax。与乳腺病变的大小、组织密度、患者年龄、绝经状态行相关性分析。所有患者均行手术治疗。结果：27例患者共32个病灶。病理证实，乳腺癌25个，良性病变7个。乳腺癌病灶SUVmax为5．08±3．55，良性病变SUVmax为1．17~-0．31，对侧正常腺体组织SUVmax为0．76±0．52。乳腺病灶SUVmax与病灶的最长径呈显著性正相关（r=0．546，P〈0．05）。病灶SUVmax与患者年龄呈显著性负相关（r=-0．45，P〈0．05）。正常乳腺组织的SUVmax与患者年龄无显著性相关（P〉0．05）。病灶与正常乳腺组织SUVmax与CT值、绝经状态无显著性相关（P〉0．05）。结论：乳腺病变患者年龄及病灶大小影响^18F—FDGSUVmax，在疾病的良恶性鉴别时应引起关注。当病变组织密度发生较大变化时^18F-FDG PET可对乳腺肿物的良、恶性鉴别提供较可靠依据。" @default.
