title: Sequential contrast-enhanced MR imaging of the penis.
abstract: OBJECTIVE
  To determine the enhancement patterns of the penis at magnetic resonance (MR) imaging.
  
  
  METHODS
  Sequential contrast material-enhanced MR images of the penis in a flaccid state were obtained in 16 volunteers (12 with normal penile function and four with erectile dysfunction).
  
  
  RESULTS
  Subjects with normal erectile function showed gradual and centrifugal enhancement of the corpora cavernosa, while those with erectile dysfunction showed poor enhancement with abnormal progression.
  
  
  CONCLUSIONS
  Sequential contrast-enhanced MR imaging provides additional morphologic information for the evaluation of erectile dysfunction.
