| 摘 要： | 背景与目的:结直肠迁延迂曲且位置不固定,肠管自身蠕动造成肠壁厚度变化。结直肠自身葡萄糖代谢不稳定,平滑肌蠕动、腺体分泌活动、痉挛、炎症等均可造成代谢异常。这些解剖和生理代谢方面的因素均会给18F-FDGPET/CT的正确诊断带来一定困难。本研究探讨18F-FDGPET/CT结直肠代谢活跃灶的影像特点及对于临床诊断的价值。方法:将74例患者共118个18F-FDGPET/CT发现的结直肠代谢活跃灶依据代谢及形态特点分为6型,局灶/CT+型、局灶/CT-型、节段/CT+型、节段/CT-型、弥漫/CT+型、弥漫/CT-型。将各分型情况与定性资料进行对比分析,采用R×C列联表χ2检验进行统计学分析。结果:118个结直肠代谢活跃灶定性为恶性共50个、非恶性68个,其中局灶/CT+型共30个(恶性23个、非恶性7个)、局灶/CT-型35个(恶性22个、非恶性13个)、节段/CT+型4个(恶性4个、非恶性0个)、节段/CT-型35个(恶性1个、非恶性34个)、弥漫/CT+型0个、弥漫/CT-型14个(恶性0个、非恶性14个)。节段/CT-型、弥漫/CT-型的非恶性病变发生率(97.1%、100%)和节段/CT+型的恶性病变...

| Abstract: | Background and Objective:The colorectum is long and its position is not fixed. The thickness of the colorectal wall is unfixed because it changes following wall contractions. The metabolism of the colorectum is not stable and abnormal metabolism results from smooth muscle movement,gland action,spasm,inflammation,and so on. These anatomic and physiologic factors can bring a few difficulties in correctly judging colorectal information on 18F-FDG positron emission tomography/computed tomography (PET/CT) scans.... |
