[MRI for etiological diagnosis of ED: Advances in studies].

ED is a common male sexual dysfunction clinically. An insight into its etiology and accurate diagnosis play a valuable role in its prevention and treatment. MRI has the advantages of high-resolution imaging of the pelvic structure, penis and brain tissue, no radiation damage, three-dimensional imaging, and functional imaging, which make more accurate the etiological diagnosis of ED. This paper presents an overview of the advances in the studies of MRI in the etiological diagnosis of ED.
