title: [The three-dimensional reconstruction of penile suspensory ligament and adjacent structures based on the MRI image].
abstract: OBJECTIVE
  To establish a three-dimensional image of the penile suspensory ligament, and explore a stereoscopic and multi angle observation method of patient' s penile suspensory ligament.
  
  
  METHODS
  This study selected the patients with small penis from our hospital as subjects. The participants were conducted on magnetic resonance imaging (MRI) examination before operation. Afterwards, the results of MRI were imported into 3D reconstruction software (MIMICS 10.0), and the suspensory ligament of penis, the pubic symphysis and other related structures were reconstructed for observation.
  
  
  RESULTS
  The pubic symphysis, penis and corpus spongiosum can be quite clearly displayed in the thin-section MRI images. In addition, penile suspensory with patchy distribution can be visible between lower part of ligament pubic symphysis and corpus cavernosum. Finally, we can reconstruct the three-dimensional structures through MIMICS 10.0, and then precisely describe the suspensory ligament's start-stop point, the angle with cavernous body of penis and the attached area in the corpus cavernosum penis.
  
  
  CONCLUSIONS
  Based on the MRI 3D reconstruction of deep penile suspensory ligament and adjacent structures, we can carry out dynamic, three-dimensional multi angle observation of patients deep penile suspensory ligament, and can use the reconstructed image to provide certain theory basis for the judgement of the corpus cavernosum penis extension length and penile suspensory ligament depth before penis extension operation.
