背景与目的 已有的研究证明:CT肺结节容积测量能够敏感反映结节容积的微小变化,在未定性肺结节的随访观察及良恶性鉴别方面具有重要应用前景。本研究旨在评估不同重建算法和层厚对CT肺结节容积测量的影响。方法 对2009年12月-2011年8月在天津医科大学总医院行未定性肺结节CT随访研究的30例患者的CT图像进行后处理分析。共获取52个肺结节,应用3种不同的算法(骨密度算法、标准算法及肺算法)及层厚(0.625 mm、1.25 mm、2.5 mm)进行9次重建。由一位放射科医师应用肺结节容积分析软件进行容积测量。应用重复测量多元方差分析、相关分析及Bland-Altman法评价结节直径、算法、层厚对容积测量的影响。结果 不同重建算法(F=13.6,P<0.001)、层厚(F=4.4, P=0.02...
