我们评估了观察者内和观察者间的变异性WA测量动脉粥样硬化BA使用HRMRI。连续10例患者接受了HRMRI，由2名独立阅片员测量三叉神经节水平BA的WA，1个月后由1名阅片员重复测量。在ICC和Bland-Altman方法中，观察者内和观察者间测量结果非常一致。通过HRMRI测量动脉粥样硬化BA中的WA具有重现性。
We evaluated the intraobserver and interobserver variability for WA measurement of an atherosclerotic BA by using HRMRI. Ten consecutive patients underwent HRMRI, and the WA of the BA at the level of the trigeminal ganglion was measured by 2 independent readers and repeated by 1 reader 1 month later. There was strong agreement for intraobserver and interobserver measurements in the ICC and by the Bland-Altman method. Measurement of the WA in an atherosclerotic BA by HRMRI was reproducible.
