Background Positron emission tomography/computed tomography (PET/CT) has made a contribution to cancer diagnosis in clinical practice extensively despite a series of inevitable defects.Diffusion-weighted magnetic resonance imaging (DW MRI), characterized by radiation-flee, no anaphylaxis to contrast media, high spatial resolution of images, high efficiency and low consumption, is gradually applied in cancer staging.However, there has been no adequate evidence of studies with large sample size and high statistical power in spite of a certain number of investigations indicating better diagnostic performance of DW MRI when compared with PET/CT.We assessed whether DW MRI is equivalent to PET/CT.
