To estimate the capabilities of magnetic resonance imaging (MRI) to identify penile anatomic structures and their topographic relationships. Penile MRI results were analyzed in 52 men of different ages who had no history, clinical, laboratory, and radiological data in favor of diseases of this organ. Penile imaging technology and its algorithm, including patient preparation and posi-tioning and a list of impulse sequences and their parameters, are proposed. Penile MRI and anatomy are described in detail; magnetic resonance signal characteristics of the main structural elements of the organ and its adjacent tissues on T1- and T2-weighted images are specified. The MRI morphometry results of the cavernous and spongy bodies, urethra, and penis as a whole, which agree well with the similar known literature data, are given. The investigation has provided evidence for the high informative value of the technique in recognizing the relatively small anatomic structures of the penis, which is comparable with that of the morphological study of a gross specimen of this organ, which in turn predetermines a further investigation of the capabilities of MRI to diagnose penile diseases and to estimate the quality of their treatment.
