1动态^(18)F-FDG PET定量分析用于骨病变鉴别诊断显示文摘目的 评价18F 脱氧葡萄糖 (FDG)PET在骨骼病变中的诊断价值。方法 研究对象为40例原发性骨骼病变患者。所有患者在注射示踪剂后立即开始动态PET采集 ,持续 6 0min。对动态PET图像进行半定量分析 ,分别计算平均和最大标准摄取值 (SUVaver和SUVmax) ,病灶SUV/肌肉SUV比值 (T/M) ,病灶 6 0minSUV/ 30minSUV比值 (SUVaver 60 /3 0min和SUVmax 60 /3 0min)等。采用Patlak作图分析法对动态图像数据进行拟合计算 ,得出摄入常数 (Ki) ,计算FDG代谢率 (MRFDG)。根据接受器工作特性曲线 (ROC)确定各定量指标的诊断阈值 ,并比较其鉴别良恶性病变的灵敏度和特异性。结果 经病理检查证实恶性病变 2 1例 ,良性病变 19例。恶性病变的MRFDG和SUV值高于良性病变 ,但各种指标的数值分布均存在交叉重叠。SUVaver与MRFDG呈正相关 (r=0 6 7)。以SUV值≥ 1 8作为阈值时 ,鉴别良恶性病变的灵敏度和特异性分别为 85 0 %和 82 4% ,以MRFDG(1 1)为阈值时的灵敏度 (82 4% )与SUV相近 ,而特异性 (92 9% )较高。同时采用SUV(1 8)和SUVaver 60 /3 0min(1 1)作为鉴别标准时 ,较之单独采用SUV特异性可改善为 93 3% ,灵敏度略有降低 (81 3% )。结论 骨骼良恶性病变之间存在葡萄糖代谢率差异。单用静态FDGPET获取SUV值不能很好鉴?吴华 Antonia Dimitrakopoulou-Strauss Thomas O-Heichel Burkhard Lehner Ludger Bernd Volker Ewerbeck Cyrill Burger Ludwig G Strauss 2002中华核医学杂志2002,22,2:3
