目的测试市售的不同灌注分析法在mr动态对比增强(DCE)成像中基于模型得出的定量、半定量药代动力学参数的可重复性。材料与方法该研究通过机构审查委员会批准并符合HIPAA标准,免去知情同意。在2010年10月1日—2010年12月27日期间共15例(年龄28～69岁,平均44岁)连续的病人在子宫肌瘤栓塞术前行1.5Tmr动态增强扫描。扫描采用可变翻转角T1成像和交错随机轨迹四维时间分辨mr血管成像。mr动态增强所采集的数据基于Tofts-Kermode模型范例用4种不同灌注分析法进行后处理。5名观察者在2011年3月13日—2011年9月8日间分别用两种不同的感兴趣区测量法测量药代动力学参数[容量转移常数(Ktrans),细胞外血管外容积分数(ve),Kep=Ktrans/ve和初始钆曲线下面积(iAUGC)],每次检查分别用不同的灌注分析法测量3次,共得出1800个数据点。结果数据标准化输出后显示大多数灌注分析法得出的平均值之间均存在显著性差异。不同灌注分析法的受试者内变异系数分别为Ktrans48.3%～68.8%,Kep37.2%～60.3%,ve27.7%～74.1%,iAUGC25.1%～61.2%。同类相关系数显示不同灌注分析法在配对比较中只有轻~中度一致性(Ktrans,0.33～0.65;Kep,0.02～0.81;ve,-0.03～0.72;iAUGC,0.47～0.78)。结论 mr动态增强扫描利用不同灌注分析法得出的药代动力学参数(Ktrans,Kep,ve,iAUGC)存在相当大的变异。目前各种灌注分析法之间没有临床可比性。因此,在将mr动态增强扫描作为一个广泛整合生物标记之前,建立一个高度统一的后处理标准是至关重要的。
