Comparison of the diagnostic performance in terms of detecting liver metastasis among T2-weighted imaging, diffusion-weighted imaging, and CT.

PPV, positive predictive value;NPV, negative predictive value;AUC, area under the curve.Comparison of the diagnostic performance in terms of detecting liver metastasis among T2-weighted imaging, diffusion-weighted imaging, and CT.

PPV即阳性预测值（positive predictive value）；NPV即阴性预测值（negative predictive value）；AUC即曲线下面积（area under the curve）。本研究对比了T2加权成像（T2-weighted imaging）、弥散加权成像（diffusion-weighted imaging）与电子计算机断层扫描（CT）在检测肝转移方面的诊断性能。
